    Design and Construction of a Supervisory Control and Data Acquisition System for full scale combustion test facility2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    One of major concerns in gas turbine industry is to reduce emissions.  Tow kind of approaches could be identified in the industry to reduce emissions, namely Primary Emission Reduction approach and Secondary Emission Reduction approach. The primary approach concerns emission prevention in combustion, while secondary approach is all about emission cleanup before releasing to the atmosphere.

    Combustion flame temperature highly influences on emissions specially NOx formation.  NOx emission is lower when the combustor operates close to lean flammability limit. Incorporating catalyst to combustor is one of methods to extend flammability limit.  Heat and Power Division at KTH-Royal Institute of Technology in Sweden has developed a test facility to test performances of catalyst in combustion.

    The combustion test facility available at Heat & Power Davison at KTH, consists of high pressure air compressor and air flow control system, air preheating unit and control system, fuel flow control system, combustor unit, and exhaust gas analyzer system. But lack of proper user interface to control and monitor the operation of the test facility through a computer work station was a major concern from experimenters.

    The purpose of the thesis work is to design and construction of supervisory control and data acquisition system for the full scale catalytic combustion test facility.  Labview 2012 is used as the main platform for implementing data acquisition and control system for the test facility. Thermocouples, pressure transducer signals, air flow meter signal are connected to Keithley 2701 data acquisition system and then connected to the computer. Fuel flow controllers are directly connected to the computer via serial port. Air flow control actuator signal is given through ADAM digital to analogue converter.

    Developed GUI is more convenient for users in terms of easy control of air flow, fuel flow and gas sampling probe systems, and monitoring of temperature, pressure measurements and exhaust gas species systems. And also GUI provides web interface to select correct conversion factor, and also to view live data recording. The developed GUI can be accessed through online to monitor the operation.

    Pappersfria informationsflöden: En fallstudie om implementeringsprocessen2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Although computers have been around for a long time and are used more and more, the use of paper inoffices remains. One of the reasons is that there are not good enough digital tools to get rid of paper from work. In this qualitative case study, the office department of ABB Components is investigating on how the implementation processes for a paperless information flows can be introduced in ways that generate benefits of working digitally.

    The result of this study will be based on data collected from interviews and observations carriedout in the office. By identifying which processes using paper in the office, different tools have been developed to facilitate the implementation. The result of this study suggests that the implementation of a paperless information flows must be a well-planned change process where tools are developed to compensate for the earlier use of paper.

    With the introduction of paperless information flows, the use of consumables will decrease and the location it takes to store these papers will disappear. This leads to more cost-effective work and less waste paper. In order for this concept to lead to a more beneficial routine it needs to be redesigned for the implementation.

    Finansiell riskperception: En studie om mäns och kvinnors riskperception vid finansiella investeringar2022Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Risk perception can be defined as people’s interpretation and subjective assessment of risk. The perception of risk is a crucial factor that is believed to impact people when taking financial decisions. Previous research shows clear differences between men’s and women’s risk taking in financial decision. Men are in general portrayed as more risk taking and not viewing risk as something problematic, whilst women are not as positive towards risk. The purpose with this study is to gain understanding of how risk perception differs between men and women when taking financial decisions, and to examine if there are any differences in men’s and women’s perception of risk throughout five dimensions of financial risk perception. To answer the study’s formulated research questions, a quantitative study in the form of questionnaire has been carried out. Collected data have been analyzed through a descriptive data analysis and t-tests. The results of this study are in line with previous research and indicate that women perceive financial risk as significantly higher than what men do. On the other hand, the study did not provide a clear result regarding differences between the genders’ risk perception in the five dimensions of financial risk perception. However, the study showed that women perceived the significant negative consequences for financial investments as significantly larger than men. This result can also be considered to be in line with previous research. Due to this, the result of the study can be seen as having contributed with further empirical support to previous scientific research regarding the differences between men and women’s risk perception when making investment decisions.

    Förändrad lagerlayout för ökad leveranssäkerhet: En fallstudie med hänsyn till den faktiska efterfrågan på Smurfit Kappa2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The purpose of the safety stock is to compensate customers uncertain forecasts. The task of operations is to be able to cover up customers fluctuations in demand. By being able to maintain a stable and competition strong delivery performance results in a safety stock to be used, however, it entails tied-up capital. The case the company has an ambition to produce larger quantities and then store it on an external warehouse that the authors have chosen to call the safety stock.  

    Purpose: The problem of actual demand is that research questions usually take into account normal demand. By trying to fill the knowledge gap, we arrive at this purpose. The purpose is to investigate how actual demand influences the design of stock layout in order to achieve the desired delivery reliability.

    Method: To be able to answer the purpose and our questions, an abductive approach has been used where theory collection has taken place from literature and articles while empirical data is collected from the case company Smurfit Kappa. During the collection of empiricism, interviews and observations have been carried out. The collected findings have been discussed with the theory to answer the purpose and questions and lead to our conclusions.

    Findings: In the current situation, the case produces the company only against client orders and that there are no products in stock. This will result in delivery times of between 8 – 9 weeks and delivery security. An existing surface is available today to create a safety layer, there is also the possibility of a larger space if desired.

    Conclusion: With a safety stock, the case company will be able to deliver the actual demand while reducing its delivery times and increasing delivery reliability.

     

    Keywords: safety stock, demand, external inventory.

    Aggregering av indikatorer och aspekter inom BRP+2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    BRP+ is a framework created to measure Swedish regional development from a quality of life and sustainability perspective. BRP + is compiled of several thematic areas which respectively include numerous aspects and indicators. To study how the regions have developed over time BRP+ uses an index year five years back in time as reference point. The first BRP+ composite index was released in 2018. This thesis is a decision-analytic review of the aggregation of aspects and indicators in BRP+. Focus lies on how the increase or decrease within one indicator corresponds to the increase or decrease within another indicator and the consequences of changing the reference year used when assessing development over time. This review has been limited to study the thematic area of Civic Engagement and Democratic Participation. The results show that the construction of BRP+ in conjunction with a change of reference year for assessing development over time has an impact on how the increase or decrease within one indicator is valued in relation to the increase or decrease within another indicator and leads to a rank reversal issue. Therefore, decision-makers may find a somewhat limited support from BRP+.

    Importance of precise gravity field modeling in direct georeferencing and aerial photogrammetry: a case study for Sweden2022In: The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLIII-B2-2022XXIV ISPRS Congress (2022 edition), ISPRS , 2022Conference paper (Refereed)
    Abstract [en]

    Direct georeferencing of airborne mobile mapping systems is developing with unprecedented speed using GNSS/INSintegration. Removal of systematic errors is required for achieving a high accurate georeferenced product in mobile mappingplatforms with integrated GNSS/INS sensors. It is crucial to consider the deflection of verticals (DOV) in direct georeferencing dueto the recently improved INS sensor accuracy. This study determines the DOV using Sweden’s EGM2008 model and gravity data.The influence of the DOVs on horizontal and vertical coordinates and considering different flight heights is assessed. The resultsconfirm that the calculated DOV components using the EGM2008 model are sufficiently accurate for aerial photogrammetrypurposes except for the mountainous areas because the topographic signal is not modeled correctly.

    Time transfer and significance of vertical land motion in relativistic geodesy applications: a review paper2023In: Frontiers in Earth Science, E-ISSN 2296-6463, Vol. 11, article id 1139211Article, review/survey (Refereed)
    Abstract [en]

    Determination of the Earth’s gravity field and geopotential value is one of the fundamental topics in physical geodesy. Traditional terrestrial gravity and precise leveling measurements can be used to determine the geopotential values at a local or regional scale. However, recent developments in optical atomic clocks have not only rapidly improved fundamental science but also contributed to applied research. The latest generation of optical clocks is approaching the accuracy level of 10−18 when facilitating atomic clock networks. These systems allow examining fundamental theories and many research applications, such as atomic clocks applications in relativistic geodesy, to precisely determine the Earth’s gravity field parameters (e.g., geopotential values). According to the theory of relativistic geodesy, the frequency difference measured by an optical clock network is related to the gravity potential anomaly, provided that the effects of disturbing signals (i.e., tidal and non-tidal contributions) are filtered out. The relativistic geodesy principle could be used for a practical realization of global geodetic infrastructure, most importantly, a vertical datum unification or realization of height systems. This paper aims to review the background of relativistic (clock-based) geodesy and study the variations of optical atomic clock measurements (e.g., due to hydrology loading and land motion).

    Open innovation - Comparing global and local approaches2014In: The 25th annual POMS conference, Atlanta, 9-12 May, 2014: Celebrating 25th Anniversary Conference : Online proceedings, 2014Conference paper (Refereed)
    Abstract [en]

    In spite of the growing interest in open innovation, one of the core questions that remain unanswered is how different kinds of openness affect innovation performance. Moreover, the impact of the geographical dispersion of partners also needs further investigation, while there is a tension between the motives for global search and the needs for proximity in innovation processes. In this paper we will research the relationship between openness and performance outcome in manufacturing companies when taking the localisation of partners into account. The study is based on survey data from 415 companies. The openness is defined by three dimensions: partner breadth, partner depth and phase depth. Performance is measured in terms of cost, risk and time-to-market, innovativeness and economic performance. The results of this study confirm and illustrate the localisation dilemma. For manufacturing companies using a global approach, it seems advisable to collaborate more intensively with a reduced number of partners. In contrast, the companies applying a more spatially balanced approach could collaborate with an increased number of partners and still be innovative and cost efficient. This implies that different localisation strategies for external partner collaborations require different integration approaches in order to be successful.

    Värdefokuserat tänkande som grund till förändringsteori för kommunal samverkan2022Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    When managing cooperation between municipalities, it is crucial to agree on the objectives of the cooperation and to have a common understanding of how the goals are to be achieved. This is important not least in order to be able to take rational joint decisions. Municipal executive directors from six collaborating municipalities have participated in the study, which examines how two methods, taken from value-focused thinking and from theory of change, can be used to develop different partners' individual goals for collaboration, merge these into a common goal structure and then use the common goal structure to create theories of change that describe how collaborative goals can be assumed to be achieved. One purpose of the study is to carry out the process and produce this material, for the benefit of the municipal executive directors and the municipalities' collaboration going forward. The scientific purpose is to see if the methods under these conditions are usable together, above all by analyzing the work process itself and the results produced in form of theories of change. The study is a case study conducted through action research, where the municipal executive directors' natural roles and forms of meeting are the arena where the joint activities and the academic study are developed together. The study describes how six individual goal structures are united in a common goal structure for collaboration. Two theories of change are then created regarding certain parts of the common goal structure. The analysis of the implementation and the material produced suggests that there is potential in combining the two methods that have been used. In value-focused thinking there is a big focus on formulating and structuring goals, in theory of change a focus is on identifying groups' common perceptions and assumptions regarding the mechanisms and processes that need to take place for change to occur and goals to be realized. Even though this is a single and limited study, it is still clear that value-focused thinking and theory of change have elements that complement and strengthen each other.

    Evaluation of ventilation for an office building: Situated in Gävle, Sweden2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Since the CO

    2-emissions and electricity prices are ever increasing many companies have tried to reduce their energy consumption in order to reduce both CO2-emissions and the cost of using energy. Therefore, in this article an office building situated in Sweden have been investigated with its current ventilation flow and what saving poten-tials can be made from heat recovery and a different ventilation flow in regards to health, energy and cost. Empirical data have been collected to be able to calculate ener-gy savings made by heat recovery and new ventilation flow. A ventilation flow of 25 l/s per office were chosen and that the conference room should have at least 3 l/s per m² the dining room and locker was not investigated thoroughly and therefore a ventilation flow from the recommendations of Sweden was followed. The total flows became, 530 l/s respectively 630 l/s for the top and bottom floor. A rotating heat exchanger with an es-timated efficiency of 80% was used for heat recovery and through the two methods combined an energy reduction up to 96,4 % for heating and 83,4 % from the electricity could be reduced.

    Tjänstekvalitet som mellanbegrepp: Om bedömning av tjänstekvalitet vid Vux Västerås2022Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att tillhandahålla vuxenutbildning är en skyldighet som Sveriges kommuner åläggs enligt Skollagen. I samma lag anges att inriktningen på det systematiska kvalitetsarbete ska vara att de nationella målen (som uttrycks i Läroplan för Vuxenutbildningen) uppfylls. Denna översiktliga formulering gör att det i stor utsträckning blir upp till varje enskild kommun att utveckla egna rutiner för arbetet med kvalitet inom vuxenutbildningen. I Västerås genomförs varje år en kvalitetsgranskning av de skolor som verkar inom den kommunala vuxenutbildningen. Granskningen omfattar bland annat strukturella förutsättningar, uppnådda resultat och efterlevnad till lag- och förordningskrav. Västerås kommun skapar och skickar ut en kvalitetsmall som fylls i av respektive skola. Detta material utgör sedan en grund (av flera) för den granskning av tjänstekvalitet som varje skola årligen genomgår. Syftet med denna uppsats är att undersöka hur tjänstekvalitet inom vuxenutbildningen i Västerås har operationaliserats till mätbara indikatorer inför kvalitetsgranskningen 2021.Utifrån teorin om mellanbegrepp analyseras vilka aspekter kommunen har bestämt ska ligga till grund för tjänstekvalitet inom Vux Västerås och också vilka följder det får om en skola inte lever upp till det kommunen betraktar som tillräcklig kvalitet.

    Arbetsmetodik för effektivisering av intern materialförsörjning2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Handling of materials sets different requirements depending on its characteristics. In order to meet internal demands of high delivery service at a low cost, it is important to design an effective supply of materials. New technology and the application of IT-systems can provide opportunities to streamline materials supply by increasing service levels and reducing costs.

    Purpose: The purpose of this study is to design and evaluate a working methodology in order to achieve effective internal supply of materials from goods receipt to production.

    Methods: A theoretical framework formed the basis to identify significant areas to achieve effective internal materials supply. In parallel, a case study was conducted at a company operating in the elevator industry. Data collection was primarily based on different types of interviews and observations to create an understanding of the company´s materials supply. The data obtained were mainly compared with the theoretical framework in the analysis phase of the developed working methodology. Conclusions was drawn, based on the analysis phase. Ethical aspects were taken into account throughout the work of this study.

    The developed working methodology: Based on significant identified areas, from the theoretical framework, a working methodology was developed to achieve effective internal materials supply, consisting of six phases: Prerequisites, Description of the current situation, Analysis of the current situation, Design of improvement proposals, Implementation and Follow-up. Four of these phases were applied on a company with the aim of designing improvements proposals with the potential to achieve effective internal materials supply. Finally, the applied phases of the working methodology were evaluated to highlight its strengths, challenges and possibilities of development as well as the further application.

    Conclusion: The significant areas and other supportive digital solutions were not considered sufficient enough to generate effective internal materials supply and thereby there was a necessity for an organized approach to utilize these areas. In order to support this, complements were required in form of a working methodology with a number of structured phases, including important considerations, which must be followed methodically in order to design improvement proposals which can achieve a more effective internal materials supply. The improvement proposals that were designed included, for instance, a new procedure for materials call-off, new principles for buffers, reduction of internal transports and automatic suggestion of place of storage.

    Effektivitetsförbättringar i interna serviceprocesser: En fallstudie inom massa- och pappersindustrin2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Effective and reliable delivery of services provides long-term performance to an organization. Inorder to create effective and reliable deliveries, activities that do not create value for the customer,namely the wastes, need to be reduced or eliminated. Value Stream mapping is a Leanmanagement tool that aims to clean processes from the wastes. With this as a starting point, studieshave previously been conducted to customize the tool for use on service processes. The studyresulted in Service value stream management, a model implemented in six steps. When the modelis applied in service processes, there is a wide variety of problems that may occur, it is therefore considered not possible to collect all problems in order to provide suggestions for improvements.

    This study aims to investigate whether the tool can be modified to better suit an internal serviceprocess in the pulp and paper industry. The literature review that has been conducted, revealedthat the existing model does not contain certain, according to the theory, important elementsadapted for Lean service. Beside the waste and tools that the model already consists of, fourrelevant wastes and twelve tools were found during the literature review. Other interestingcomponents that emerged through the literature review, were the views of what an organizationshould learn about and how successes should be measured. In order to fulfill the purpose of ourstudy, the Lean tool Service value stream management, was tested with the additions found duringthe literature review. The test was conducted at an internal service process at a case company tosee if there is evidence to add or remove some of the new wastes, tools or components to themodel. At the case company, data was collected through interviews and observations as well asthrough a survey. The study resulted in the 5K-model which consists five steps to eliminate andreduce wastes. With this model, organizations in the pulp and paper industry should be able tocreate higher efficiency in their internal service processes. To visualize and measure efficiency, amathematical formula was developed that could be considered useful even outside the 5K model.

    Towards the integration of sustainability in Higher Education Institutions: a review of drivers of and barriers to organisational change and their comparison against those found of companies2017In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 166, p. 563-578Article, review/survey (Refereed)
    Abstract [en]

    In recent years, there have been a considerable number of efforts to integrate sustainability into Higher Education Institutions (HEIs); however, there are still challenges that need to be overcome. A process that has received an increasing attention has been the Organisational Change Management for Sustainability. This article is aimed at reviewing the main drivers of the integration of sustainable practices and the barriers to change slowing or stopping it. A systematic literature review was carried out using Web of Science de Thomson Reuters and in Scopus databases focusing on retrieving all papers on sustainability in HEIs published between 2000 and 2016. The drivers of and barriers found for the integration of sustainability in HEIs were compared to those previously described for companies. The similarities on drivers to change found in HEIs and companies were greater for external ones. A lower number of barriers to change were reported in the literature for HEIs than those reported for corporations, nonetheless, it was found that HEIs and companies have several common barriers to change. The article proposes a list of main drivers of and barriers to change, some general and others context specific. The findings on the drivers of the integration of sustainable practices in HEIs can serve to identify additional good practices at companies and vice versa. The barriers to change detected for the process of integration can help into anticipating, preventing and overcoming them. This knowledge can help institutions better plan and use their resources in working to becoming more sustainable.

    An Analysis of a Sustainability Index2021In: Sustainable Consumption and Production, Volume 1: Challenges and Development / [ed] Ranjula Bali Swain; Susanne Sweet, Cham, Switzerland: Palgrave Macmillan, 2021, p. 39-63Chapter in book (Refereed)
    Abstract [en]

    In this chapter, we perform a conceptual analysis of a household sustainable consumption index, whose construction is based on guidelines in a handbook issued by OECD. We conclude in our analysis that the designers of the index treat the concept 'sustainable consumption' as a descriptive concept, and argue that this interpretation is a conceptual mistake.  A consequence of this mistake is that the construction of the index is treated as a kind of statistical and empirical problem only. Instead, we argue that sustainable consumption is a specific kind of value concept named intermediate concept, whose function is to link descriptive grounds with normative consequences, and thus that the construction of the index is a normative problem. That is, the construction of a sustainable consumption index should be regarded as a normative multi-attribute decision process. A policy implication of our study is that when measuring sustainability, a decision analytic approach based on an adequate interpretation of the concept sustainability as an intermediate concept should be employed. In order to avoid low validity of sustainability indices as a result of making a conceptual mistake, it is possible to explicitly treat the construction of a sustainability index as a normative multi-attribute decision process that can be aided by decision support tools. The relevance of our analysis to policy makers and other stakeholders is that it contributes to a deeper understanding of what kind of concept sustainability is and what it means to measure such concepts. Without a proper understanding of the nature of this concept, there is an obvious risk of low validity of its measurement.

    Utvecklad value stream mapping för en varierande produktion mot kundorder: En fallstudie vid Karl Hedin Emballage AB2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: Today’s high demand on customer specific products has led to an upstream of organizations that are adapting an make-to-order production strategy. Seeing that these organizations compete by obtaining low lead-times and the ability to present unique and affordable products, a need has been created to use lean-based methods in attempt to reduce waste, create an efficient production, thus to gain competitive advantage. The issue is that lean-methods are not developed for these types of organizations. 

    Purpose: The purpose of this study is to compile a model that describes how an organization that is characterized by make-to-order strategy and with a high variety in products manufactured in low volumes can implement value stream mapping to create an efficient production and thus gain competitive advantage.

    Methodology: The study is carried out through a case-study on a company that manufacture based on the specification of customer-orders. To perform a value stream mapping, relevant literature was collected and studied. Consequently, interviews and observations were conducted and constitute the empirical data. Subsequently the literature review along with the empirical data constitutes the conclusions and findings.   

    Results: The case company is characterized by a complex manufacturing of unique products with crossing information- and material flows which complicates value stream mapping. The processes consist of manual cutting, semi-manual cutting, plywood cutting, component manufacturing, and assembling. Processes with similar operations were spread throughout the manufacturing plant and the assembly points were identified as bottle-necks.  

    Conclusion: A model that describes how an organization that is characterized by make-to-order strategy and with a high variety in products manufactured in low volumes can implement value stream mapping has been compiled. Furthermore, additional aspects have been identified that are significant in the implementation of value stream mapping within this form of production.

    Processkartläggning av servicesystem: För första återkoppling till kund och utformning av en förbättringsmodell2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Strukturering och planering har länge varit känt som viktiga faktorer som påverkar hur en verksamhet ska fungera. Förståelsen för detta har inte alltid varit densamma. Längre tillbaka fanns inte kunskap om vad detta gav. Forskning har under åren genomförts angående planering och strukturering och olika resultat har framkommit. Efter dessa resultat har principer vuxit fram som har haft påverkan på arbetssätten. Längre tillbaka låg fokus på produktivitet medan det idag har flyttats till människan och dess välbefinnande.

     

    Framgångsrika företag har genom åren studerats för att kartlägga deras framgång. Utifrån dessa data har sedan företag försökt att kopiera rakt av till sin egen verksamhet, något som sällan har lyckats. Eftersom det inte finns någon optimal lösning för alla utan varje företag eller organisation behöver se till sina behov och anpassa arbetssätten efter dessa.

    Syftet med detta arbete är att undersöka vilka delar som är viktiga i ett servicesystem för att få en välfungerande verksamhet.

    Vid kontakt med det valda företaget hade de problem med att uppnå en kundåterkoppling inom rimligt antal dagar. Därför är det av intresse att se över vilka delar som är viktiga i ett servicesystem för att genom en förbättring av systemet uppnå en bättre kundåterkoppling.

    Med detta menas att se över processen från det att en motor inkommer eller en kund lägger en beställning till dess att kunden har fått ett svar, en återkoppling, med kostnad och tidsplan. Förbättringsmodellen som tas fram teoretiskt över ett system ska avgränsas till serviceinriktade och bortse från producerande.

    För att göra det möjligt att besvara syftet har observationer, intervjuer och litteraturstudier genomförts. Dessa metoder har på olika sätt bidragit till att framställa en förbättringsmodell för servicessystem, som svarar på syftet. Den slutgiltiga förbättringsmodellen innehåller fyra hörnstenar vilka är: information, logistik, Lean och kvalité. Information och logistik framkom från fallstudien och Lean och kvalité framkom under litteraturstudierna. Alla fyra hörnstenar uppmärksammades i både fallstudien och litteraturstudien, de belystes dock lite olika.  

    Då förbättringsmodellen var framtagen jämfördes den mot ABB i Storvik för att se om den fungerar mot ett verkligt företag och inte bara är teoretisk tillämpbar. Efter denna jämförelse drogs slutsatsen att den är användbar som modell för servicesystem

    Effektivisering av materialförsörjning inom tillverkande industri: En fallstudie på Företaget2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    How companies choose to design their supply chain is important for their competitiveness. Supplier relationships are becoming increasingly important to maintain a market position. A key factor for success is to deliver material in the right quantity, at the right time and to the right place. Other factors that play an important role are quality standards, leadership and above all, customer first. The customer should be placed at the top of the value chain, and be treated with respect. Markets are driven by short lead time and companies cannot rely on brand loyalty.

    The purpose of this study is to develop a general model for analysis and improvement of the supply chain for manufacturing companies, with focus on components from external suppliers. The model is created based on a literature review and to examine this, the model was tested at Företaget. The empirical data is mainly conducted by interviews, complemented by one observation. The analysis model consists of seven areas based on Supply Chain Management, Logistics and Lean. A key factor to analyze these seven areas is to map the current situation. The results have been filtered through the analysis model and have led to suggestions for improvement. These suggestions are only recommendations and the companies choose what to take further into action.

    Företaget is one of Sweden’s leading window manufacturers with two strong brands, Produkt 1 and Produkt 2. Most of the production process is carried out in Edsbyn and the size of the factory is as big as ten football pitches at 65,000 squares meters. Wooden-aluminum windows are an increasing trend and stands for two thirds of the sales. The study is focusing on one selected component which is the flow for aluminum profiles.

    The conclusion shows that supply chain management, logistics and Lean play an important role while building an efficient supply chain. Relationship, communication and information sharing with suppliers are of great importance and needs to be constant developed and improved. Leadership is a key element to get all the areas to work and it is the leaders that characterize the culture of the company. The study has resulted in a number of improvement suggestions for Företaget. One suggestion for improvement is to develop a routine for documentation when a deviation occurs in the final assembly. This will enable the follow-up and help to find the main cause for appearance.

    Managing the bi-directional flow of materials to increase customer satisfaction and reduce cost: A case study at Sandvik Mining and Rock Technology2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: This thesis explores the bi-directional flows of material perceived by manufacturing firms in the supply chain and accordingly derive suggestions to properly manage these flows to increase customer satisfaction and reduce cost.

    Methods: A literature review was summarized in a conceptual framework. This framework was then illustrated in a case. In this case, 11 semi-structured interviews, 3 participant observations and 3 types of archival records were collected. Analysis and discussion of the preliminary conceptual framework compared to the case was the basis for the modified conceptual framework that was designed.

    Main findings: In general material flows downstream the supply chain, but because of quality issues, recycling or returns material need to flow upstream the supply chain. This thesis provides a holistic view of how to manage these flows with a modified conceptual framework.

    Academic contributions: Previously, almost no academic research has been conducted on decision variables when it comes to managing material flows upstream the supply chain. This thesis contributes to closing this gap by suggesting different actions to properly manage the bi-directional flow of material. Furthermore, previous research addressing how to manage material flows has been re-accessed and expanded.

    Managerial implications: By using the framework, practitioners can determine helpful activities to increase customer satisfaction and reduce cost. This means management gets directions of where to allocate their resources.

    Limitations: The perspective and evidence in this research are only collected from the manufacturer’s point of view, valuable insight from suppliers and customers may have been overlooked. The suggestions of how to manage the bi-directional flow of materials have not been tested and the outcome of these recommendations has not been compared to KPIs or other measurements.

    Implementering av DevOps: En fallstudie på ett IT-konsultföretag2021Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Within the field of project management different methods and agile approaches have emerged. However, dividing silo-structures have created frustration within software development. DevOps has surfaced as a way to address this and instead connect different functions such as development and operations. DevOps affects teams but there is no standardized approach for its implementation. Therefore, more research around the implementation process of DevOps is needed. Also, investigating what the accompanying effects could be, is of interest. The purpose of this thesis is to study the implementation of DevOps within the IT consultant industry and what impact it has on a team. This thesis was executed with abductive reasoning where a case study was carried out. To fulfill the purpose and answer the research questions literature review and interviews have been performed. Collected theory and empirical material have been discussed and analyzed in order to formulate conclusions and recommendations.  One formulated conclusion is that each implementation of DevOps needs to follow its own adapted execution where the aim and essence are clarified. Factors regarding communication, automation, responsibility, willingness to change and collaboration also impact the implementation and the effects experienced by the team. It can also be concluded that both benefits and limitations can affect the team yet, the disadvantages often appear to be contained within the start of the implementation. A practical contribution comes from recommendations for the implementation, such as having a dedicated person and education within DevOps among others.

    Multicriteria Decision Analysis in Wastewater Treatment2022Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The wastewater industry is critical for both current and future human life. At the same time, competitive conditions of market spaces lead to technology evolution reaching continuously new frontiers. While many wastewater treatment plants are designed identically in different global loci, wastewater characteristics are unique and therefore decisions related to wastewater treatment technologies are very critical. Wastewater characteristics vary due to cultural and climate factors, among other things and thus, each wastewater treatment technology must be studied independently. Hence, decision analysis and decision making are an integral part of the industry. A multi criteria decision analysis (MCDA) has been applied in this thesis, including a fictional decision-making problem. Furthermore, this thesis describes an analytic approach to a complex decision-making problem in wastewater treatment by using multi attribute utility theory (MAUT). This thesis assigns utility values, applies Swing Weighting (SW) which is not commonly used in the wastewater industry and assesses weight coefficients for the utility functions for each criterion. The goal is to illustrate how proportional scoring can be used to assign utility values in different aspects related to wastewater treatment, how SW can be performed to assess weight coefficients that are related to wastewater treatment and finally how the additive utility can be applied to deliver the total utility. For this reason, a hypothetical decision problem was developed, in which, the decision maker can select amongst three different wastewater treatment technologies using sustainability criteria. This is a multi-dimensional problem that requires the use of a structured approach to analyze the options accordingly. More, six criteria are used to rank three different wastewater treatment technologies with respect to sustainability. Finally, the MCDA results from this hypothetical decision problem show how proportional scoring, SW, and the additive utility could be used in the selection of a wastewater treatment technology however it should be tested with real life decision problems.

    Student perspectives on flipped classrooms in engineering education2016In: Proceedings of the 12th International CDIO Conference / [ed] J. Björkqvist, K. Edström, R. J. Hugo, J. Kontio, J. Roslöf, R. Sellens, & S. Virtanen, CDIO , 2016, p. 1041-1050Conference paper (Refereed)
    Abstract [en]

    We used focus group interviews and the student perspective in order to investigate student perceptions of flipped classroom in engineering education. The learning environment included web-based interactive video films, where students had to answer quizzes in order to continue seeing the films, and interactive in-class sessions with clickers. In general the students had experience of flipped classroom in many courses and subjects, and could compare different implementations in physics, mechanics and calculus. We studied perceived advantages, strengths, drawbacks, or difficulties, and students’ views on learning with flipped classroom. Overall, the students were positive, or in one case indifferent to flipped classroom. They saw many advantages, but they also pointed out difficulties and had many opinions about how a flipped learning environment was best implemented. In the interviews, they also expressed their views on learning and described how they studied. Many used rote learning and surface approaches to learning, but many also had a focus on understanding. Some declared an intention to focus on understanding but still used rote learning. Some students expressed a strategic approach to learning with focus on the examination. Heavy workload and a threatening examination system seem to favor surface approaches to learning also in a flipped classroom learning environment. One of our interviewees had dyslexia and described her experience and special conditions. We conclude by suggesting a list of five key elements for flipped classroom. We think that the interplay between these elements is important, and that they are considerably weaker without the support of the others.

    'Känslig personuppgift' som mellanbegrepp2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Den snabba tekniska utvecklingen och en ökad globalisering som har skett i världen under de senaste decennierna har bidragit till en större exponering av digitala data och därmed skapat större risker för otillbörlig behandling och användning av person-uppgifter. Skydd av personuppgifter regleras av en EU-förordning som heter Gene-ral Data Protection Regulation (GDPR) som trädde i kraft 2018. En kategori av per-sonuppgifter som har fått ett starkare skydd i GDPR är känsliga personuppgifter. Syftet med denna studie är att göra en inledande analys av begreppet ’känslig per-sonuppgift’ som ett mellanbegrepp, med fokus på begreppets grunder och följder vad beträffar tillåten behandling av känsliga personuppgifter inom ramen för GDPR. Genomförandet består av analys av källmaterial som utgörs av lagtext som beskriver begreppet ’känslig personuppgift’ och undantagssituationer som tillåter hantering av denna uppgift (Artikel 9 i GDPR). Resultatet är en analys av begreppet ’känslig per-sonuppgift’ med sju grunder och två villkorliga normativa följder. Följderna innehål-ler tio undantagsvillkor för tillåten behandling av känsliga personuppgifter. Det har visat sig att både grunderna och de tio undantagen potentiellt innehåller mellanbe-grepp som inte är så tydligt formulerade i lagtexten och därför kan kräva en djupare analys. Det kan också vara fallet att det finns ett behov av att vidare analysera grun-derna och undantagen som så kallade grundöppna mellanbegrepp.

    Demand management: the role of cross-functional integration in a context of political turbulence2020In: Asia Pacific Journal of Marketing and Logistics, ISSN 1355-5855, E-ISSN 1758-4248, Vol. 32, no 3, p. 817-839Article in journal (Refereed)
    Abstract [en]

    Purpose

    The purpose of this study is to investigate how cross-functional integration supports the execution of the demand-side processes and its effects on both the demand and supply-side processes.

    Design/methodology/approach

    A case study was conducted including a Brazilian multinational manufacturer in the automobile industry and some of its suppliers and dealers. 17 interviews were conducted. A theoretical framework is proposed containing five basic elements, they are: characteristics of the demand/supply processes; involved functions; integration factors; context influencers and impacts of integration on demand and supply processes.

    Findings

    The findings present three demand-side processes (Product Launch, Marketing and Sales and Demand Planning) that demonstrated a greater need for cross-functional integration in the studied case, mainly through informal integration factors.

    Research limitations/implications

    The empirical results of this study have methodological limitations due to the use of the case study method. Future research should analyze the effects of other context influencers (e.g. natural catastrophes, civil wars and low level of unemployment) on cross-functional integration.

    Practical implications

    The results highlight that joint planning, willingness to work together, team spirit, adequate communication and cross-functional meetings helped the studied organizations to achieve competitive advantages and improve their performance.

    Originality/value

    This study provides a theoretical framework that helped to improve the understanding of the interrelationships between demand management constructs and cross-functional integration factors. There are indications that a political–economic crisis has stimulated the existence of a willingness to work together and group spirit among employees who remain in the organization after mass dismissals. This climate of cooperation helped to increase the agility and resilience of the studied supply chain, which is currently affected by a changing market.

    Sustainability reporting in public sector organisations: exploring the relation between the reporting process and organisational change management for sustainability2017In: Journal of Environmental Management, ISSN 0301-4797, E-ISSN 1095-8630, Vol. 192, p. 292-301Article in journal (Refereed)
    Abstract [en]

    Sustainability Reporting has become a key element in different organisations. Although there have been a number of academic publications discussing the adoption of sustainability reports in the public sector, their numbers have been quite low when compared to those focussing on corporate reports. Additionally, there has been little research on the link between sustainability reporting in Public Sector Organisations (PSOs) and Organisational Change Management for Sustainability (OCMS). This paper focuses on the contribution of sustainability reporting to OCMS. A survey was sent to all PSOs that have published at least one sustainability report based on the GRI guidelines. The study provides a critical analysis of the relation between sustainability reporting and OCMS in PSOs, including the drivers for reporting, the impacts on organisation change management, and the role of stakeholders in the process. Despite still lagging in sustainability reporting journey, PSOs are starting to use sustainability reporting as a communication tool, and this could drive organisational changes for sustainability.

    Kvittningsmetoden vid rekrytering2022Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A recruitment process can be demanding work for the hiring manager where the applicantsmay have to be compared with regard to several aspects. Doing this holisticallycan be difficult and important details can be missed. Using a theoretical frameworkcan therefore facilitate this work. The even-swap method is a decision analyticmethod that can be effective when comparing alternatives with many aspects. Thepurpose of the study is to investigate whether the even-swap method can be a toolfor recruiting managers in a recruitment situation. To investigate this, six managerswith personnel responsibility were interviewed. After an initial pilot interview,some changes were made to the interview planning and another pilot interview wasconducted. Before the first interview, the respondents had to take part in a fictitiouscase with a list of ten candidates, five of whom would be selected to proceed to interview.Each candidate was described based on a number of aspects whose relevancewas mentioned up in the situation description. A few days after this, the managerswere interviewed regarding their choices, whereupon a text describing theeven-swap method, as well as a consequence matrix with a ranking table, was sentover to the respondents so that they could prepare for interview round two. A newinterview was then scheduled where they would apply the even-swap method to thesame fictitious situation. The result showed that all managers changed one to threecandidates in the comparison between the choices when applying their own methodsof approach and when applying the even-swap method. The managers expressed aninterest in using the method as a tool in future recruitments as it enabled a goodoverview of the candidates and thereby contributed to minimizing the risk of detailsbeing missed. At the same time, the managers felt that the method was initially difficultto use, and some indicated that they had difficulties with the valuation regardingthe swaps. The study indicates that the even-swap method could be a useful tool in arecruitment process provided there is enough practice and that it is applied in theright way at the right stage of the process.

    Fallgropar vid offentlig upphandling ur ett beslutsteoretiskt perspektiv2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Upphandlingsprocessen kan ses som en form av beslutsprocess. Inom beslutsteori har det under flera år forskats om psykologiska fällor och misstag vid beslutsfattande. Det finns en hel del teorier om hur dessa fällor och misstag kan undvikas. Syftet med denna studie är att jämföra fallgropar vid beslutsfattande med fallgropar vid offentlig upphandling samt analysera hur resultaten från den beslutsteoretiska forskningen kan användas som stöd i upphandlingsarbetet. Resultatet visar att likheterna är många och att resultatet från den beslutsteorietiska forskningen på ett enkelt sätt kan konkretiseras och användas i upphandlingsarbetet.

    Prioritet för planerbara åtgärder inom hälso- och sjukvården: - Analys av aspekterna prioritetsgrad för åtgärd och patients hälso- och sjukvårdsbehov som flerdimensionella begrepp2023Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Hälso- och sjukvården ska verka utifrån olika lagar där hälso- och sjukvårdslagen beskriver målsättning och riktlinjer för hälso- och sjukvården. Hälso- och sjukvården kan behöva genomföra prioriteringar om det finns brist på kapacitet till att ge vård till alla invånare som har hälso- och sjukvårdsbehov samtidigt som vården ska ges på lika villkor. Vid kapacitetsbrist ska hälso- och sjukvårdens resurser enligt hälso- och sjukvårdslagen prioriteras till de patienter som har bedömts till att ha ett högre hälso- och sjukvårdsbehov framför de patienter som har bedömts ha ett lägre behov. Att prioritera innebär att ”rangordna eller välja ut” och är centralt vid beslut om när ett vårdbehov är mer angeläget att tillfredsställas före ett med ett lägre vårdbehov. Syftet med examensarbetet är att analysera några centrala begrepp som finns inom lagstiftning och styrdokument för offentlig hälso- och sjukvård med koppling till bedömning av patients hälso- och sjukvårdsbehov och prioritetsgrad på åtgärd. Med aggregationsteori som teoretiskt ramverk analyseras begreppen hälso- och livskvalitetstillstånd, hälso- och sjukvårdsbehov, hälso- och livskvalitetseffekt och kostnadseffektivitet som flerdimensionella aspekter som är centrala vid bedömningen av en åtgärds prioritet. Ett resultat av analysen är aggregationsträd som visualiserar den grundläggande strukturen för de sammanvägningar som behöver göras i samband med bedömning av prioritetsgrad för åtgärd inom hälso- och sjukvården. Resultatet skulle kunna användas i vidare arbete att skapa mer transparenta och jämlika prioriteringsbeslut som i förlängningen kan skapa vård på än mer lika villkor för befolkningen.

    Värdering av vårdhygienisk kvalitet på sjukhusavdelningar2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Vårdrelaterade infektioner är bland de vanligaste orsakerna till vårdskador i svensk sjukvård. Att förebygga vårdrelaterade infektioner kräver ett målmedvetet arbete med hygienrutiner i alla delar av vårdkedjan och att de vårdgivande enheterna får tydlig och konkret återkoppling på sitt vårdhygieniska arbete. Syftet med detta magisterarbete var att ta fram en modell för att, med hjälp av beslutsteoretiska metoder, sammanfatta de kvalitetsmätningar som görs på ett svenskt sjukhus (Södra Älvsborgs Sjukhus, Borås) för att ge en återkoppling av den vårdhygieniska kvaliteten hos sjukhusets avdelningar. Arbetet genomfördes som ett aktionsforskningsprojekt, där teori och praktik samspelar i ett cykliskt förlopp för att lösa ett specifikt problem. Slutresultatet blev en färgkodad matris över mätvärden kopplade till olika jämförelsenivåer. Modellen ger en helhetsbild där detaljer samtidigt framgår tydligt, men saknar den viktning av olika aspekter som är vanlig inom beslutsteoretiska bedömningsinstrument. En tydlig utmaning var att beslutsteoretiska modeller kan upplevas som abstrakta och svårförståeliga för en lekman, vilket till viss del begränsar deras användning som ett återkopplingsverktyg.

    Energikartläggning med fokus på ventilation: En fallstudie som undersöker underhåll och dess inverkan på fastigheter2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    För att kunna reducera de effekter som klimatförändringarna orsakar behöver energisystemen effektiviseras. Eftersom fastighetsbeståndet idag mestadels består av äldre byggnader, blir renoveringar och effektiviseringar viktiga för att kunna få ner energianvändningen. För att renovering och effektivisering ska gynna både klimatet och fastighetsägaren bör det planeras långsiktigt redan från start samt inkludera ett livscykeltänk. Syftet med detta arbete är att utföra en energikartläggning av en kontorsbyggnad från 1988 som är belägen i Gävle samt presentera eventuella energibesparingsåtgärder. Huvudfokus har varit på frågan om hur olika typer av underhåll och underhållsskulder påverkar en fastighet, med störst inriktning på den tekniska utrustningen. Metoder som använts i arbetet har varierat från praktiska mätningar till en litteraturstudie och intervjuer. För att få en inblick om förvaltningsbolag vet vad en underhållsskuld är skickades en enkät ut med några frågor kring ämnet. Energikartläggningen visade att kontorsbyggnaden är i bra skick och de åtgärder som presenteras berör ventilation och värmesystemet. Ett byte av ventilationsaggregatet föreslås som reducerar värmeanvändningen med 15 % och elanvändningen med 28% samt minskar utsläppen med 2,7 ton CO2 per år. Återbetalningstiden är lång, men en LCC-kalkyl beräknad på 20 år redovisar att bytet är lönsamt långsiktigt. Behålls det gamla aggregatet kan tilluftstemperaturen sänkas och innetemperaturen justeras ned med någon grad. Detta bidrar till att reducera värmeanvändningen med 13 %. Resultatet som framkom i litteraturstudien samt intervjuer visar att eftersatt underhåll leder till att fastighetens värde minskar och att pålitligheten för systemen reduceras, vilket ökar risken för dåligt inneklimat. Det förebyggande underhållet syftar till att utrustningen ska hålla optimal prestanda medans felavhjälpande underhåll sker när komponenten tappat sin funktion. Förebyggande underhåll visar sig mer kostnadseffektivt jämfört med felavhjälpande underhåll. Arbetsbelastningen och underhållskostnaden kommer öka i takt med underhållsskulden samtidigt som en försämring av fastighetens livslängd sker. Sammanställningen av enkäten visade att förvaltningsbolagen har koll på vad en underhållsskuld är och att de svarande bolagen jobbar med ett livcykeltänk.

    Optimering av tillverkningskvantiteter2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    För att öka lönsamheten hos ett tillverkande företag är det viktigt att ha optimala tillverkningskvantiteter så att resurserna utnyttjas optimalt. Hur ett tillverkande företag utnyttjar produktionen påverkar effektiviteten i produktionssystemet, lagret och hos personalen. Syftet med denna studie är att hitta en metod för att optimera tillverkningskvantiteter så att kostnaden per produkt blir så låg som möjligt. I denna studie har vi använt oss av företagets distributör i Indien som ett exempel för hur en manuell produktion ser ut i dagslägen och jämför hur kostnaderna skulle se ut om denna produktion skulle ske maskinellt.

    Arbetet är en fallstudie där tillverkningskvantiteter analyseras. Både kvalitativ och kvantitativ forskning har bedrivits för att få en djupare förståelse av problemet. I arbetet ingår bland annat teorier som rör lager, partiformning och kostnader som rör tillverkning och orderhantering. Ett antal observationer och intervjuer har utförts för att för att få en djupare inblick i tillverkning och hantering av produkter hos företag. Empirisk data som nämns är beskrivningar av företagets produktionssystem och lager.

    Denna studie resulterar i att ”företag” bör använda partiformningsmetoden "Ekonomisk orderkvantitet" för optimering av tillverkningskvantiteter. Metoden går ut på att balansera ordersärkostnader och lagerhållningskostnader. Är dessa kostnader likvärdiga uppnås den mest kostnadseffektiva tillverkningskvantiteten. Studien har resulterat i en lathund där den mest optimala tillverkningskvantiteten presenteras beroende på produktefterfrågan per år.

    En analys av distributören Indiens order resulterar i att ”företag” bör producera ordrar likt Indiens beställningar maskinellt istället för omarbetning manuellt vilket sker i dagsläget. Redan vid en tillverkningskvantitet på 120 produkter är maskinell bearbetning mest kostnadseffektivt jämfört med en manuell ombearbetning.

    Beslutsanalys av medicinska åldersbedömningar inom asylprocessen2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A framework for a decision analysis method that is based on the principle of maximization of the expected utility regarding alternatives of age assessment for unaccompanied asylum seekers is here presented. Using the framework, different methods (dental, knee joint, hand wrist and the method used by The National Board of Forensic Medicine (RMV) that combines the methods for dental och knee joint) for medical age assessment are compared. These methods are further compared with three benchmark alternatives, (i) to trust the age given by the unaccompanied asylum seeker which results that all are considered to be children, (ii) to consider all the unaccompanied asylum seekers as adults and (iii) the absurd alternative to flip a coin to decide who is a child or an adult.

    For the decision analysis, assumptions and/or estimates for the age distribution of the unaccompanied refugees are needed and estimates for the different methods regarding how probably it is to be considered an adult given the actual age. The outcome of a child that is incorrectly classified is assumed to give the lowest utility and a correct classification (both children and adult) is assumed to give the highest utility. The utility of the outcome of an adult that is incorrectly classified as a child needs to be quantified.

    The age distribution of unaccompanied refugee, considered for age assessment is here assumed to be a combination of two continuous uniform distributions, with the interval 15-18 years (child) and 18-21 years (adult). Two utility models are examined, a discrete model that only consider if the individual is a child or an adult and a continuously linear utility model that consider the age difference from 18 years given an incorrect classification.

    The analyzes carried out demonstrates how the framework can be used in practice. Given the assumptions that are made the conclusion is that the alternative that gives the highest expected utility depends on the prevalence (proportion of adults) together with the valuation of the utility for an incorrect classified adult. Regardless of the valuation, when the prevalence is close to 0 all should be considered to be children, when the prevalence increases should be replaced with a method that largely classifies children correct when the prevalence is further increased should be replaced with a method that largely classifies adults correct and finally, when the prevalence is close to 1 all should be considered as adults.

    Anticipating a bid/no-bid decision model for an ICT service company2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report analyses and describes how the bid/no-bid decisions are made at one ICT service company. The analysis is based on current available research within the area of multi criteria decision analysis to enhance the company’s decision process. It proposes how the bid engagement decision can be structured and evaluated. Through a questionnaire at the ICT company, data from its own bids was collected to identify the factors perceived to be relevant to the bid/no bid decision. It is found that the factors can vary depending on industry, market and potentially bid situation, requiring experts’ assessment of which factors to use for each bid situation. Concluding the study, an initial bid model is proposed, but with reservations due to lack of validation in real life situations. A recommendation to expand the existing bid model with probability distribution based risk estimates is made.

    Framgångsrik Implementation av Lean: Förbättrade möjligheter med implementationsmodell2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Lean production is the name given to Toyota’s Production System (TPS) by the west. The continuous improvements of their operations through Lean has made Toyota into the largest car manufacturer in the world. This, in turn, has led to several studies regarding both Toyota and their system as to find ways to apply Lean in other organizations. Even so, over 90 percent of all companies fail to implement Lean. Thus it becomes increasingly interesting to research as to how Lean, successfully, should be implemented.

     

    The purpose of this thesis is to construct a model which will aid companies with the implementation process and to further the rate of success. Factors regarding what makes for a successful as well as a failed implementation will be analyzed. 

     

    A case study is used with two different companies in order to analyze empirical data in comparison to earlier research. One company represents a more successful case and the other a less successful one. 

     

    The main findings of this paper is the order of which different aspects of Lean is to be implemented to increase the possibilities for successful implementation. Furthermore the emphasis on a, for Lean, correct leadership within the company that requires genuine understanding and commitment.

     

    The conclusion is displayed as a model where one can see the crucial steps in order to increase the success rate regarding the implementation of Lean. The main points of the model is the importance of support from leaders in combination with an accepting culture where people are of significant importance. The model can be viewed in chapter 6.

    Energikartläggning av Kv. Freden, Gävle: Simulering av åtgärder och dess energibesparingspotential med modellerings- och simuleringsprogram IDA ICE2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Carbon dioxide levels are increasing as a consequence of larger energy use worldwide. This has led to regulations and rules of emission and energy consumption. In order to stop global warming and reduce energy consumption, EU has agreed on four common goals to achieve by the year 2020, also known as the 20-20-20 goals. Sweden has also come up with its own environmental goals to achieve by the year 2020. They include increasing the share of renewable energy by at least 50 percent, improve the use of energy by at least 20 percent and increase the share of renewable energy in the transportation sector by at least 10 percent.   Due to the laws and requirements related to stricter energy consumption and carbon emissions companies strive to use more energy efficient technology and more energyconscious behavior. Energy audit is an effective and an important tool in identifying and illustrating a company's energy usage for the clarification of future measures and improvement.  The thesis aims to illustrate Kv. Freden's use of energy and come up with both economically and energy saving measures to reduce its and other similar building's energy consumption. Six questions have been used to determine the energy distribution in the building and find defects in the management and maintenance of the indoor climate and develop cost-effective solutions for the choice of measures.   Five methods were chosen for approaching and answering the questions. A literature review was performed using keywords such as "Energy Saving", "Energy Audit" and "Behaviour" in online databases containing scientific articles. Thereafter an empirical analysis of the data supplied for the building was performed, which enabled modeling and simulation of the building in the program IDA ICE 4.6.1. A thermography and a qualitative survey regarding energy conscious behavior were performed as proof of assumptions.  The ventilation in this thesis is found inadequate after applied methods.  With simulated FTX-systems installed in the building, a maximum energy saving potential about 17 percent is achieved, which corresponds to a energy use of 97 kWh/m2. Excluding FTX, the simulated measures which prove to be the most profitable for the building is the sealing of doors and windows in order to reduce infiltration. These two measures are the most cost effective energy saving solutions regarding Kv. Freden and similar buildings.  The building's simulated energy use is represented by 29 percent electricity and 71 percent of district heating usage, which compared with the energy data provided by Gävle Energi relates to a reliability equivalent to 97.5 percent and 96 percent. The simulation program IDA ICE proved to be an efficient tool for the simulation of a building's energy use and application of possible measures.

    Application of Decision Analytic Methods to Cloud Adoption Decisions2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis gives an example of how decision analytic methods can be applied to choices in the adoption of cloud computing. The lifecycle of IT systems from planning to retirement is rapidly changing. Making a technology decision that can be justified and explained in terms of outcomes and benefits can be increasingly challenging without a systematic approach underlying the decision making process. It is proposed that better, more informed cloud adoption decisions would be taken if organisations used a structured approach to frame the problem to be solved and then applied trade-offs using an additive utility model. The trade-offs that can be made in the context of cloud adoption decisions are typically complex and rarely intuitively obvious. A structured approach is beneficial in that it enables decision makers to define and seek outcomes that deliver optimum benefits, aligned with their risk profile. The case study demonstrated that proven decision tools are helpful to decision makers faced with a complex cloud adoption decision but are likely to be more suited to the more intractable decision situations.

    In-House Delivery: An Analysis of a Materials Supply Model at Ericsson Corporation2008In: Proceedings of ICESAL 2008, 2008, p. 223-237Conference paper (Refereed)
    Abstract [en]

    This paper gives an account of and analyzes a concept for materials supply within Ericsson Corporation. The study is focused on the customer’s point of view. The concept, called by Ericsson In-House Delivery (IHD), could be identified as a manual form of the principle of Vendor Managed Inventory (VMI). In IHD the supplier has the responsibility for dimensioning the customer’s production store and also for physically replenishing the storeroom without any traditional purchase orders or transactions in IT systems regarding inventory control. This method contrasts with the more traditional Material Requirements Planning (MRP), which is more dependent on data than IHD is. IHD also differ to how VMI normally is implemented using IT-based solutions. IHD could be an uncomplicated method for manufacturing companies to manage non-critical purchased parts or standard parts with low economical importance, and its use could help the company achieve its logistics goals.

    En undersökning av Söderhamns kommuns avgifter för bostadsarrenden: Förslag till marknadsanpassad prissättning2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Söderhamns kommun, belägen på Sveriges östkust, är upplåtare av bostadsarrenden med anknytning till Söderhamns skärgård. Avgifterna för bostadsarrendena har inte följt den prisutveckling som skett på fastighetsmarknaden de senaste åren därför var syftet med detta arbete att beskriva och analysera en marknadsanpassad arrendeavgiftsnivå samt en marknadsanpassad prissättning vid friköp av arrendetomter som ägs av kommunen. En skälig avkastning på mark som utarrenderas ansågs vara 3 – 4 %. Målsättningen var att ta fram förslag på prissättning av bostadsarrende som Söderhamns kommun skulle kunna använda sig av.

    I denna rapport har kvantitativa metoder använts, den första var att beräkna ett simulerat markvärde för bostadsarrendena och utifrån det erhålla en årlig arrendeavgift. Den andra var ortsprismetoden där både sålda fastigheter i Söderhamns kommun samt arrendeavgifter för bostadsarrenden i olika kommuner jämfördes för att få fram årliga arrendeavgifter och den tredje var avkastningsmetoden där friköpspriserna vid friköp av arrendetomterna beräknades. Slutligen gjordes en ekonomisk rekommendation av de årliga arrendeavgifterna och friköpspriserna. I en karta som skapades med hjälp av Geografiskt informationssystem (GIS) har de årliga arrendeavgifterna från metoden "simulerat markvärde" visualiserats för att lättare kunna analyseras och förstås. Beräkningarna resulterade i olika förslag på årliga arrendeavgifter utifrån de tre metoderna samt förslag på friköpspriser av arrendetomter.

    En svårighet med arbetet var att hitta information om tillvägagångssätt vid prissättning av bostadsarrenden, trots detta har vi dragit slutsatsen att resultatet från "simulerat markvärde" borde visa de mest rättvisa arrendeavgifterna och friköpspriserna, men det bästa är att jämföra arrendeavgifter i närliggande områden.

    Decision and Policy Making in the European Union: Role of EU Agencies in the decision and policy making in the area of chemicals and food safety2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    EU regulations, decisions and policy making are matters that concern every resident in the EU and risk and benefit assessment and analysis form part of the EU decision and policy making. This thesis discusses the decision/policy making in the EU and the risk assessment activities of the European Food Safety Authority (EFSA) and the European Chemicals Agency (ECHA), as well as ECHA’s socio-economic analysis activities. It also studies the role of the European Commission and the Comitology process. The EU regulates what chemicals or food stuffs/ingredients, for instance additives, may be made available in the European market. How the decisions are made about what is allowed and what not, and who makes those decisions, is not necessarily evident due to the complexity of the processes. In this thesis the decision making at different stages of the EU regulatory processes has been identified and analysed in order to find out by whom and how the decisions are made. The method used was a literature search with an overview of the existing theories and research from the areas of EU decision making, risk assessment and risk management. The regulatory processes were studied from a decision making perspective with the aim to identify and record possible decision making opportunities of different actors beyond the European Commission. The decision making opportunities were classified and organised based on their level of impact to the processes. Two real cases were studied: the restriction of lead in jewellery under REACH Annex XV restrictions and the authorisation of ammonium chloride in food under Flavourings regulation. Decision making opportunities and methods were looked for in those processes. It was found that while, in the studied cases, there appeared possibilities to ensure science based good regulatory decision/policy making, it remained uncertain and possibly politicised. It was also revealed that in certain steps the processes lacked transparency.

    Kvalitetsbrister i medelstora företag: En arbetsmodell för kvalitetsförbättring2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    When a new product is launched, product defects in various processes and process steps willprobably appear that were not previously known or detected. The purpose of this study is to create aworking model for how middle-sized companies should manage to handle defects in quality thatwill appear in manufacturing productions. To be able to create a realistic model, this thesis will bebased on a case study of a manufacturing company by the name of AQ ParkoPrint AB, located in Gävle, Sweden.

    The following research questions are answered in order to support the main purpose:

    • What defects in quality occur most often in middle-sized manufacturing companies?

    • How can these defects in quality be managed, and if possible, be reduced?

    The methods used in this study are interviews and observations. Five interviews and twoobservations were performed on AQ ParkoPrint AB. The working model that was created wasnamed “Five-step-model” and involves the process of managing defects in quality divided into fivesteps: document, investigate, illustrate, propose action and implement. The “Five-step model” isdesigned for middle-sized manufacturing companies focused on creating a way to worksystematically with how to managing quality defects and how to reduce them if possible. The stepsin this model are flexible because every single company should be able to customize each step tosuit their company needs, and only use the “Five-step model” that is created in this study as thebasic structure of the quality work. The case study shows that the suppliers are the majorcontributors of causing quality defects. Middle-sized companies can use the developed five stepmodel to handle and reduce their quality defects. The “Five-step model” itself requires no expensivetools. It is the extent of the work in every specific step that determines the costs.This study also presents some question formulations that companies can use to reduce their qualitydefects that can be traced back to the subcontractors.

    Analysis and improvement of the ventilation system in a shopping centre in Gävle (Sweden)2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Currently, because of the large use of energy in developed countries, the European Union accepted some targets to obtain some savings in the energy use. A review showed that around 20 % of the final energy use in non-residential buildings in Sweden comes from heating, ventilation and air-conditioning system (HVAC). The main motivation of this project is found in the necessity to move towards a more sustainable buildings, making a responsible consumption of the energy.

    The research focuses on the heat recovery unit of the ventilation systems of a shopping centre in Gävle, Sweden. The aim is to assess the reasons generating low energy savings and thereupon, propose some measures to obtain a better efficiency in the systems.

    The analisys has performed as follows: studying the systems, facility conditions and operation point. To evaluate the efficiency of the heat recovery, it was necessary to measure the temperature, velocity, and mass flow within the installation using a thermo-anemometer, infrared thermometer and TA-Scope devices. Lastly, all the collected information was considered to achieve the results.

    Finally, it has found that leakages generating heat losses and the incorrect airflow running the ducts are the main problem for the low efficiency.

    The study concludes that replace the isolation in some systems and make and adjustment of the airflows and fluid in the pipes, help to increase the efficiency. These measures allow to increase as maximum in 24 % the energy savings from the current conditions. To conclude, it has achieved the target of the project increasing the energy savings.

    Energieffektivisering på Skutskärs Bruk: Varvtalsstyrning till utvalda pumpenheter på Blekeri 42012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In modern society in terms of economics and environmental impact, it is important to ensure that a company is as energy efficient as possible to reduce the amount of energy used. About 10 TWh of electricity used annually to pump drives in Swedish industry. Therefore, pumping system has great potential for energy savings.

    The objective of this report was to determine how much energy and money that can be saved with the insertion of variable speed drive to six pumps on Bleach plant 4 in Skutskär Mill. The work was performed with electrical measurements during one week, analysis of pump curves and the compilation of production data over a year.

    The results show that four of these six pumps were profitable and yielded an annual saving of 1172 MWh of electricity and 560 000 SEK. With an economic lifetime of 10 years and a discount rate of 6.8% the final result for the entire life-cycle savings became 3 355 000 SEK. The conclusion was that it is preferred to introduce variable speed drive on pumps with a motor power above 50 kW.
