    The impact of object size and precision demands on fatigue during computer mouse use2011In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 13, no 3, p. 118-127Article in journal (Refereed)
    Abstract [en]

    Prolonged computer use, especially if fatigue ensues, is associated with visual and musculoskeletal symptoms. The aim was to determine the time-course of perceived fatigue in the wrist, forearm, shoulder and eyes during a 60-min mouse task (painting rectangles), and whether object size and/or mouse use demands were of influence. Also, we investigated performance (number of rectangles painted), and whether perceived fatigue was paralleled by local muscle fatigue or tissue oxygenation. Ten women performed the task for three conditions (crossover design). At condition 1, rectangles were 45 × 25 mm, square paint cursor size 1.3 × 1.3 mm, and mousepointer movement ratio 1:26. At condition 2, the same cursor size and mousepointer movement ratio was used, but rectangles were smaller. At condition 3, the smaller rectangles were used, but the cursor size was also smaller and mousepointer movement ratio was 1:8. The results showed increased self-reported fatigue over time, with the observed increase greater for the eyes, but no change in physiological responses. Condition 2 resulted in higher performance and increased eye fatigue. Perceived fatigue in the muscles or physiological responses did not differ between conditions. In conclusion, computer work tasks imposing high visual and motor demands, and with high performance, seemed to have an influence on eye fatigue.

    Relationen mellan kalkyleringsmetoder, Lean och produktionsflöden av kundanpassad karaktär: Hur kostnadsprecisionen i förkalkyleringen i denna typ av produktion kan ökas samt vilken kalkyleringsmetod som passar bäst2015Independent thesis Basic level (university diploma), 180 HE creditsStudent thesis
    Abstract [en]

    Since the manufacturing industry is heading for a higher level of customization and implementation of Lean, at the same time as outmoded traditional costing methods is still used in modern industrial organizations, it is interesting to explore the relations between production flows of customized character, Lean and different costing methods.

    The purpose of this thesis is to increase the cost precision in the preliminary calculation for a product flow of customer adapted and Lean character, and to describe a generalizable work process for this. The purpose is also to develop general recommendations regarding the choice of costing methods by, on a basis of the character of this production, a comparative analysis of costing methods (traditional costing methods, ABC and Lean accounting/VSC). Through a literature study and a case study of a production flow with a high level of variety and influence from Lean, both of the purposes has been fulfilled.

    The case study has been accomplished through interviews and observations. Problems and positive elements that according to literature characterize the production of customized products have also been found in the case company. That connection has been used to support the analysis of the relations. The relations between costing methods, Lean and production flows of customized character has been analyzed through a comparison between findings in literature and results from the case study. It has been found that Value Stream Costing (VSC) is the most appropriate costing method for production flows of customized products that has reached a high maturity level of Lean.

    The preliminary costing is dependent on reliable operation times which have been produced on the case study company, while a general work process has been developed. The operation times were in this case identified through video recordings of the production moments and a following analysis in the software AviX. By following the general work process that has been developed, useful material for preliminary costing and continuous improvements in the production flow will be obtained.

    Since research is showing that Lean should be implemented in the whole organization if full advantages of Lean shall be obtained, VSC is found to be an ideal costing method to replace outmoded, traditional costing methods at the same time as this costing method simplifies costing in production flows of customized character.

    Modelling of metal removal rate in titanium alloy milling2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Titanium is one of fourth most abundant structural metal in earths soil. It is in a composition with other elements, forming titanium alloys. These alloys are used in many different areas, such as medical, energy and sports, but is most commonly used in aerospace applications. Titanium alloys have different solid phases, α, α+β and β depending on temperature and the amount of α and β-stabilizers.When machining titanium alloys, one of the most important factors to control is the temperature in the cutting zone. The built-up heat in the cutting edge of the tool, are connected to titanium alloys low thermal conductivity and high heat capacity, which means that the alloy has low heat conduction from the cutting zone. The temperature is strongly depending on the cutting speed, which is the relative speed difference between the cutting tool and the workpiece. Many studies and research work have been conducted surrounding this fact, focusing on the physical and chemical quantities, to model tool wear progression and how this affects the tool life and the metal removal. These models are often implemented and analyzed in finite element software providing detailed but time-consuming solutions.The focus for this work have been on developing a suitable tool life expectancy model, using design of experiments in combination with metamodeling to establish a model connecting cutting parameters and measured responses in terms of tool life, from a conducted milling experiment. This models where supposed to provide a platform for customer recommendation and cutting data optimization to secure reliable machining operations. The study was limited to focus on the common α+β titanium alloy 6Al-4V. The outcome and conclusion for this study, is that the tool life is strongly connected to the choice of cutting speed and the radial width of cut and that these parameters can be predicted by the two models that have been develop in this project. The models ensure the highest possible metal removal rate, to selected parameters.

    Systematiskt arbetsmiljöarbete: Nyckelpersonsintervjustudie om uppfattning kring arbetsmiljöarbete, lönsamhet och prioriteringar på en arbetsplats2008Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Asplund, L (2007). Systematic Work Environment Management: Key Informant Interviews about Apprehensions, Priorities and Profitability. Examination paper in Pedagogy, 15 hp. Master’s Programme. University College of Gävle. Department of Education, Curriculum Studies and Psychology.

    Background

    Every fourth Swedish employee has been found to suffer from some form of work-related ill-health. Legislation, termed Systematic Management of Workplace Environments (SAM), has been enacted to promote optimal physical and psychosocial workplace environments. Em-ployers are obliged to follow the regulations issued by the Swedish Work Environment Au-thority [Arbetetsmiljöverket] and are responsible for operating active workplace environ-ment management plans. Such plans can prevent ill-health and, in some cases, increase the company’s profitability.

    Purpose

    A medium-sized, retail trade company from in central Sweden was chosen in order to study and analyze how systematic workplace management environment practices were imple-mented in relation to other management priorities and company profitability.

    Sample

    The key informants were chosen out of the personal manager who was the first contact on the company. Seven key informants, selected on the basis of their knowledge of their com-pany's Systematic Work Environment Management, participated in the study. An additional key informant was later chosen to validate the results. The informant composition was: three informants from middle management, with 5 to 7 years experience of the company, one supervisor (1 year), and three other members of staff (2 and 3 years.) Six qualitative in-terviews were carried out, within the period of one week, in the interviewees' offices. The validating interview was undertaken 4 weeks later, also on the company’s premises.

    Design and methods

    The company specialized in retail furniture. Non-structured interviews, based on an inter-view guide with 11 open-ended questions, were used. The interviews, lasting about 30 mi-nutes each, were recorded and transcribed. Statements were analyzed for notable differ-ences, similarities, themes and patterns. The statements were then categorized and sub-jected to further analysis.

    Results

    All the informants felt that the company’s actual practice met the work environment stipula-tions and was on-going. They agreed that workplace environment in general is considered an important issue, but that the company could probably do more to meet the intentions of the work environment legislation. Two specific focal points appeared in the results: ergo-nomic improvement in the workplace and the informants’ aspiration to implement and de-velop a system of caring telephone calls to employees absent through illness.

    Conclusions

    Management was seen as giving contradictory signals. On the one hand they say that work environment is active and ongoing and on the other hand agree that not enough is being done. The expression of intent does not appear to be matched by actions. Improved educa-tion in systematic workplace environment management would give employees a better un-derstanding of work environment and how systematic workplace management is supposed to operate. The analysis of the informants' suggestions led to a series of proposals for im-provements in workplace environment management strategies. A new plan for employee participation would involve employees being more directly and actively involved with work environment and increase support for the work of the safety representatives.

    Supplier Management in Chinese State-owned enterprises: A case study of bounded relationships from the perspective of buyer2011Independent thesis Advanced level (degree of Master (One Year)), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Motivation: Chinese stated-owned enterprises (SOEs) play an increasingly role in Chinese economy although, its management for its suppliers are yet not in an effective manner in the situation mentioned in this case. Even though the Kraljic (1983) matrix is commonly used as a guideline for how to manage suppliers, there is a lack of studies based on Kraljic that have analysed the situation where the buyer are bound to and unable to switch its suppliers.

    Purposes: the purpose of this paper is to first to analyse the situation in the case by applying the Kraljic matrix, and second to explore the major challenges in terms of cost, communication and supplier selection in dealing with the supplier relationships. Specifically the analysis concern how factors like political risk, “Guanxi” and CSR restrict the way the case company manage its suppliers. In addition, appropriate supplier management strategies are formulated based on the findings.

    Research methods: in order to achieve the purposes of this paper, first an extensive literature review related to this paper was conducted. Afterwards, a case study of a subsidiary of Sinopec was carried out. The discussion concerns different types of the suppliers who are categorized according to the Kraljic matrix. Interviews with these two managers are major source of data collection.

    Findings: as indicated from the purpose the findings from the case confirm that Kraljic matrix is inadequate to capture the case of Chinese SOEs in this paper. The subsidiary does not either select or evaluate suppliers based on cost efficiency. Further, it is shown that political risk “Guanxi” and CSR influence the way the way the firms manage its suppliers.

    Implications: training design including all levels of managers and exploiting the use of “Guanxi” is two of appropriate strategies recommended for improvements in current situation

    Utformning av en arbetsmodell för införande av lean inom sjukvården: En fallstudie på Gävle sjukhus2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    Introducing lean production principles in health care is a relatively new area. The county council in Gävleborg and Gävle hospital are interested in shortening their health queues with help from logistics methods and lean production principles. This is among others because of growing health queues at the urologist reception in Gävle hospital. Lean production is a concept arising from the Japanese car industry, meaning a quest to do more with less. In Swedish lean production can be translated to resource- economic production and the work with lean production includes principles like customer focus, teamwork and continuous improvement.

    The purpose with this thesis is to compile a working model which can be used when implementing lean principles in health care. This is because the health queues to the reception today are long and some kind of transform is necessary. The working model consists of six different levels, mapping, analyze, developing improvement suggestions, balancing, implementation and follow up. The first four steps in the working model will be introduced in this thesis, although the last two steps are outside the limits of this thesis.

    By using logistics methods and lean principles in mapping and analysis of the receptions processes some problem areas have been discovered. The discovered problems have been analyzed and improvement suggestions to the different problem areas have then been elaborated. The improvement suggestions which have been elaborated with help from logistics methods and lean production principles can contribute to a decrease of the urologist receptions health queues.

    Distribution av bensin och diesel från Gävle Hamn: Analys av alternativa distributionssystem2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Sammanfattningen syftar till att ge en övergripande bild om vad arbetet handlar om, för att skapa en nyfikenhet till att läsa hela arbetet.

    Studiens syfte var att analysera alternativa distributionssystem för petroleumprodukter från Gävle Hamn. Där vi har valt två slutdestinationer, norra Stockholmsregionen med Brista som ett alternativ och det andra alternativet är Västerås. De faktorer som vi har utgått från när vi har analyserat distributionssystemen är ekonomiska, miljömässiga och tekniska möjligheter.

    Den metod som användes var kvalitativ och det empiriska materialet inhämtades genom intervjuer. I studien har nio respondenter intervjuats, vi anser att de personerna har varit relevanta för studiens syfte. Resultatet har analyserats med hjälp av tidigare forskning och teorier inom ämnet.

    Resultatet visade att det skulle vara ekonomsikt, miljömässigt och tekniskt möjligt att starta upp petroleumtransporter till norra stockholmsområdet. Till Västerås fann vi inga belägg för att ett alternativ där båten först går till Gävle Hamn för att sedan lastas om till tåg skulle bli billigare eller bättre ur miljösynpunkt. Det fanns även tekniska aspekter som gjorde kapaciteten sämre till Västerås än till norra Stockholm. Därför anser vi att det nuvarande alternativet ska användas till dess att nya förutsättningar börjar gälla.

    Att etablera ett tredjepartslogistikföretag i Kina2010Independent thesis Basic level (university diploma), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The purpose of this examination thesis is from a Supply Chain Management perspective to examine the conditions for establishing a third party logistics company from the European Union in a growing industrial area in China. The thesis focuses on Xiaohe district in Guiyang.

    Logistics industry is one of the fastest growing industries in China. The Chinese Government is proposing a promotion policy for a logistics expansion that includes tax reductions and reduced prices on rent and land prices for logistics companies. The main difference between the European Union market and the market in China is the cultural differences in the way of doing business and to socialize. Corruption may occur in China and it is worth to examine Chinese firms before cooperation can be settled. If collaboration is carried out, it may be advantageous to find out if there are specific rules in China to reduce the risk that problems occurs with the goods to be exported and/or to be imported. A product to be imported or exported between the European Union and China must clear customs.

    When it comes to growing industrial areas as in Guiyang there are geographical advantages with thought of trading, that the city is adjacent to several other provinces and that it is regarded as a tie point in southwestern China. The main industry involved in the city includes coal, iron, steel, aluminum, fertilizers and manufacturing. Local Chinese logistics companies have lack of the experience and skills that is needed for providing logistics solutions to companies in the industrial park in Xiaohe District in Guiyang. Furthermore, there are no third-party logistics providers in the city. Partly for this reason, it is a great advantage for a third party logistics provider from the European Union who wants to establish business in Guiyang. The weaknesses for establishing include lack of infrastructure and long distance to the closest seaport. Furthermore, there is a plan for development in the region which includes the development of transport infrastructure.

    Exploring the portfolio approach in purchasing and supply management: - the result of an international survey2010Independent thesis Advanced level (degree of Master (One Year)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Although many scholars assert that portfolio approach can facilitate purchasing to live up to its strategic importance and contribute to company performance; and practitioners have applied portfolio approach in various purchasing activities, there are still limited empirical researches to confirm that portfolio can actually create the benefits. The purpose of the study is to explore the usefulness of portfolio approach as well as why companies decide to apply portfolio approach in purchasing and supply management.

    Based on an international survey carried on a large number of European and North American manufacturing companies, the findings of the study provide strong evidence on the significant impact that the purchasing portfolio approach has on the business results, and also shed lights on the strategic importance of purchasing as a direct explanation to the application of the approach by companies. The empirical study confirms that the competency of the purchasing professionals plays a prominent role on the path of transforming the strategic importance of purchasing, with the help of portfolio approach, to the success of improved purchasing performance. A cross-discipline theoretical study reveals that different models share a common theoretical foundation and consist of similar basic elements in their construct.

    The results of this study fill the research gap in analyzing the causes of the application of portfolio approach; provide quantitative empirical proof on the usefulness of portfolio approach in the industrial companies and thus give support to the existing theories. The study contributes to a growing research stream on how to improve purchasing business performance, reflecting the increasing strategic role that purchasing is given. The results send useful messages to company managements and provide valuable insights on an important tool for improving purchasing business performance.

    Foreign market entry strategies: a case study for a Chinese pump manufacturer2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Economic globalization, regional economic cooperation and knowledge economy make a great impact on the development of the new century. The changes of international trade and investment reflect the variety of the world economy development; the world economic development, in turn, influences the international trade and investment in both quality and quantity (Feenstra, 1998). The international marketing has become an important trend in this modern society, global strategy has been put at the top of the agenda of many companies. And making development in the international market can also be a good solution for the companies to increase their competition (Mittelman, 1996). It is vital for those companies to deal with foreign market entry as a first step in accomplishing their global mission (Onkvisit & Shaw, 2004).  How to enter a foreign market is very important in this case, so the purpose of this work is therefore to research important factors on entering a foreign market. The theories, including environmental assessment before entry and foreign market entry strategies, are summarized by literature review and in order to make the theories applicable, a case study on a company inChinahas been done in this work as well. The methods used in this work include collecting processed data from literature review, gathering primary data by telephone interviews and through e-mails. SWOT analysis is used to assess targeted market for the case company. The case company is Shandong Shuanglun Group which is a famous pump manufacturer inChina; its targeted market that the company wants to enter is the Italian market. After SWOT analysis, the conclusion of this work indicated that opportunities of entry targeted market for the case company includes favorable tax policies and relevant laws, the threats in high context culture and terrorist activities should be paid attention to. The company has strengths in product but weaknesses in service, strategic alliance with one local pump manufacturer and exporting could be their market entry modes.

    Gender diversity and innovation in mining – a corpus-based discourse analysis2017In: International Journal of Gender and Entrepreneurship, ISSN 1756-6266, E-ISSN 1756-6274, Vol. 9, no 4, p. 359-376Article in journal (Refereed)
    Abstract [en]

    Purpose The purpose of this study is to gain increased knowledge about gender diversity and innovation in mining by analyzing how women are discursively represented in relation to these two concepts, and in doing so establish how diversity management is received and communicated in the industry. Design/methodology/approach The study is based on analysis of texts including references to gender diversity and innovation in mining found on the web. The tool used to retrieve the data has been WebCorpLive, a tool designed for linguistic analysis of web material. Findings Although increased female representation is communicated as a key component in the diversity management discourse, based on the idea that diversity increases innovation and creativity, closer analysis of texts on diversity and innovation in mining shows that what women are expected to contribute with has little explicit connection with innovation. Research limitations/implications The study contributes with increased knowledge about diversity management by providing an example of how it is received in a traditionally male-dominated industry. Practical implications Our findings indicate that for diversity management to have a real effect in mining, it needs to be based on gender equality and social justice motives, rather than on a business case rationale ? the principal motive today. To enable this change stereotypical gender patterns, as shown in this study, need to be made visible and problematized among policy makers, practitioners and actors on all levels of the industry. Originality/value The study contributes with new knowledge about gender in the mining industry previously not attended to by using a method which so far has been sparsely used in discourse analysis, although pointed out as promising.

    Wallpaper drying solutions: Feasibility study of a low temperature drying process2008Independent thesis Advanced level (degree of Magister), 20 points / 30 hpStudent thesis
    Abstract [en]

    The wallpaper company Duro Sweden AB, one of the most important Scandinavian

    wallpaper manufacturers, wants to decrease its energy use and costs and make its

    production more environmentally friendly. It implies changes in the key process energy

    use whom consists mainly by drying process using heat production from oil.

    The purpose of this project, studied by the consulting company Sweco Theorells AB,

    is to determine the feasibility of a change in the energy utilisation implemented to the

    most representative process to propose future solutions’ basis on the future energy

    question.

    The company use mainly two kind of energy, electricity with 1055MWh per year and

    oil with 1985MWh per year. The oil power consumption and cost represent respectively

    65% and 73% of the global part.

    Several proposed changes with better energy efficiency are presented : use of district

    heating as a heat source, Infrared Drying, combination, etc; but due to the important

    rebate make by the Swedish government on the oil price, they are not currently viable to

    achieve.

    But the constant rise of the oil price could be sooner a strong incentive to make these

    improvals, strongly environmentaly friendly and power consumption reducer,

    economicaly viable in the long term.

    Produktionsrelaterad förändring för ett bättre logistiskt flöde med mänsklig hänsyn: En fallstudie på PEPAB Produktionspartner AB2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: The business world is in constant change, which means that businesses must be able to adapt to these changes and constantly improve. The research field on how businesses should achieve a smart material supply is small, which emphasizes the importance of studying how a company can change its production layout to improve its internal logistics.

    Purpose: The purpose of this study is to increase the understanding of the production layout's importance for the material supply and the human aspect in production-related change work.

    Method: The study has used an abductive, exploratory approach to answer the purpose and the research questions. This means that studies of theories were done in parallel with studies of the empirical material at the case company PEPAB Produktionspartner AB. Theories from the literature and the empirical data have been analyzed and discussed in order to draw conclusions.

    Findings: The results are a description of the current internal material flow of four representative components and a description of employees´ attitude to change. By mapping the material flow, logistics flow factors and human related factors have been discovered. 

    Theoretical contribution: When changing the production starting from the logistic factors waiting, unnecessary inventory, unnecessary manufacturing, defects, unnecessary transportations and improperly designed production layout a better logistical flow and better material supply can be achieved. Combining this with a well-planned preparatory work with related training can make a successful change. 

    Practical contribution: This study contributes practically with a new production layout that enables a better logistical flow. It also emphasizes the importance of a well-thought-out and wellplanned preparatory work to maintain the staff´s sense of participation.

    Lean and the implementation process: managers perspective on change2011In: Det nya arbetslivet, 2011Conference paper (Refereed)
    Abstract [en]

    Introduction and aims: Research has shown that view on Lean production differs both between researchers and practitioners and that there is no uniform definition of the concept (Emiliani 2006; Pettersen 2009). Furthermore, the perspective on Lean production as toolbox or philosophy, sometimes expressed as Lean thinking, influences the Lean implementation. Implementation of Lean can be seen as a project or an initiation of an ongoing developmental process where learning is taking place (Rother 2010). The purpose of this paper is to survey managers´s wiew of lean in terms of “toolbox Lean” or Lean thinking and their view of the implementation process in terms of a project with a time limit or as an initiation of an ongoing developmental process. The intention is to increase understanding about the relationship betweenhow Lean production is defined and implemented.

    Method: This paper is based on a case study at a Swedish manufacturing company aiming tobecome a company working with a business system based on Lean principles. The study has a multilevel, vertical, perspective covering five hierarchical management levels in the organization, from president of the company to first line managers at the shop floor. Data was collected through individual semi structured interviews with 14 managers at different organizational levels.

    Findings and reflection: The view on Lean has, according to managers, evolved at all management levels within the organization during the implementation. From a starting point were Lean was perceived as a set of tools by most, it has, as the managers increased their knowledge evolved into a view that is more complex and also includes behavioral and cultural issues. This would indicate that even if the starting point of an implementation of Lean is Lean tool focused it may over time come to include issues of management protocol addressing cultural development, coaching and communication as learning regarding the organizational needs take place. The interviews showed that managers on different hierarchical levels of the organization believed there to be differences in view regarding Lean within the organization. We however found the view on Lean to be quite similar at all management levels, described as a customer focused; standardized way of working that is continuously improved by keeping a process focus. The impression of there being differences in view regarding Lean is most likely caused by a lack of dialogue between organizational levels within the organization. Varying competence levels regarding Lean and thereby varying ways of working within the organization may create a lack of support between production and support functions. Health and health promotion are seen as important factors at the production unit that was studied.

    Research limitations: Organizational size and only partial coverage of the organization may limit the results validity to the parts of the organization that was researched and to larger organizations.

    Value: This paper provides insights regarding the learning process connected to a Lean implementation and that alterations of perspectives and needs may take place during such a process.

    Keywords: Lean production; Lean management; Lean implementation

    Trading Oil Futures2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    Oil is an important energy source and a necessary industrial raw material. Every country’s economic growth and the daily life of its people are dependent on this energy form.

    Historically, the oil prices have varied significantly on the world market. This led to at least two oil crises when prices increased in a very fast pace. In order to reduce such rapid fluctuations, oil was introduced at so called commodity exchanges. At such trading places oil could be traded openly for future delivery and hence the market was aware of price changes in advance. A commodity exchange sells special contracts in the form of so called “futures”. In fact there are many different contracts, each exchange has its own set of them covering for a number of different oil types. This thesis deals with these contracts and how they are traded.

    Affärssystem – Utmaningar och framgångsfaktorer för en framgångsrik implementeringsprocess: En multipel fallstudie för små- till medelstora företag verksamma i naturstensbranschen2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Enterprise resource planning system (ERP system) is a standardized support system that aims to support the various functions of a company. Companies have different conditions for a successful implementation process due to the complexity of the ERP system. Implementation of ERP systems is also considered to be particularly difficult in small- to medium sized enterprises (SME) because the process is depending on resources. The natural stone industry is unique because of the natural material that require great adaptation and selection. Only about 20% of the material that is mined from the bedrock can be used for further production. SMEs and the natural stone industry have been dedicated to a little attention in research when it comes to implementation of ERP systems. Therefore, two knowledge gaps are identified where one gap represents a lack of literature on ERP systems for SMEs and the other represents the natural stone industry's unexplored conditions and challenges regarding the implementation of ERP systems. The purpose of this work is therefore to identify critical success factors as well as challenges small companies operating in the natural stone industry possess in order to implement an ERP system and how these companies can avoid a time-consuming process with high costs.

    To realize the purpose a survey was sent out to companies operating in the natural stone industry and are members of the Swedish Stone Industry Association. Thenceforth four interviews have been conducted with three companies who are members of the Swedish Stone Industry Association and a consultant working to implement ERP systems was interviewed. The theory is chosen based on the purpose and has been collected from scientific articles, literature and websites explaining key concepts for the work. Based on the findings, a model has been created to represent a cross-industry approach to achieve a successful process for ERP system implementation. The model aims to demonstrate an approach which is to create an awareness of any challenges that may arise. Challenges such as material characteristics, lack of leadership and lack of a holistic perspective. Based on these challenges, companies should then focus on success factors such as user attitudes for ERP, the use of project teams and a parallel test system to generate a successful implementation process.

    Integrerade ledningssystem: Drivkrafter, möjligheter och hinder2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The world is changing and the business context is no exception. One of the clearest tendencies is a tougher business climate with harder competition due to increased international trade and the expansion of the e-business. At the same time the customers are becoming more sophisticated and demanding. The last decades have also meant that tougher and more frequent demands are being aimed at the businesses from a wider variety of stakeholders; demands regarding how environmental issues, social responsibilities and business ethics should be dealt with. All of the above have driven companies towards implementation of different management systems to be able to cope with the demands as well as to ensure that these issues are being dealt with in an efficient and effective manner. The result is that there might be quite a few management systems that have to be handled, usually a time consuming and bureaucratic task. Theory in the field suggests that an integration of the different management systems is logical and profitable as well as beneficial in many other aspects. Some of the benefits that could be gained due to the holistic approach that the integrated management system (IMS) provides are an alignment of goals and strategies as well as elimination of duplications and sub-optimizations. The IMS will also provide an opportunity for companies to strive towards sustainable development in a balanced manner. Despite this not many companies have intentionally sought to integrate their management systems. Researchers within the field note that there is a lack of empirical data to support the theories regarding how companies act when integrating their management systems, knowledge that might provide insights why integration and IMSs is not more widespread.Hence it is interesting as well as theoretical motivated to further study this area, especially as IMSs might be an aid on the companies’ journey towards sustainable development, a highly important issue. This qualitative multiple case study aims to contribute with knowledge regarding how Swedish companies have handled the issue of IMS, more specific, what driving forces, opportunities and hindrances they have experienced associated with IMS. This, as the knowledge about Swedish firms is limited. The research questions are answered through interviews with managers responsible for the management systems. The findings suggest that companies with more than one management system integrates them to some degree, however not always intentionally, and that it might be a lack of clear motives, driving forces and stakeholder demands that limits further or full integration. The outcome is that integration primarily becomes a coordination of existing management systems with purpose to reduce bureaucracy and redundancies.

    Fostering sustainable technologies: A framework for analysing the governance of innovation systems2011In: Science and Public Policy, ISSN 0302-3427, E-ISSN 1471-5430, Vol. 38, no 5, p. 403-415Article in journal (Refereed)
    Abstract [en]

    The development and diffusion of technological innovations need governing in order to contribute to societal goals related to sustainability. Yet, there are few systematic studies mapping out what types of governance are deployed and how they influence the development and diffusion of sustainable technological innovations. This paper develops a framework for analysing the role of governance in innovation systems aimed towards sustainability. The framework is based on the literatures on governance, technological innovation systems and socio-technical transitions. We foresee empirical studies based on the framework that may serve as a needed input into governance processes. © Beech Tree Publishing 2011.

    Improvements in the competitiveness of Chinese military-ownedhotel through TQM2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Nowadays, China has the tendency that more and more military-owned hotels are shifting toprivate hotels gradually over time. Military-owned hotels have various disadvantages.However, they also have many reasons to exist as well. This thesis aims to answer theresearch question on how the military-owned hotels can deal with the privatization tendencythrough the application of TQM systematically. Case study and literature review are used tofind out the answers to the research question. Two case hotels, one military-owned hotel andone private hotel, are considered in this thesis. In order to guarantee the privacy of the twohotels and their staff, the military-owned hotel would be called Hotel A, and the private hotelwould be called Hotel B. By reviewing various TQM theories, five important aspects in theparticular quality management system have been identified for the case hotels. Finally, ageneralized quality management system model is developed for Chinese Military-ownedhotels in order to make them survive in the competition with private hotels.

    Methodological variance associated with normalization of trapezius EMG using submaximal reference contractions2006In: Proceedings of the 16th World Congress of the International Ergonomics Association / [ed] Ernst Koningsveld, 2006Conference paper (Other academic)
    Abstract [en]

    While electromyography (EM G) is commonly used to quantify levels of muscle activity in different jobs and tasks, less attention has been paid to the size and sources of exposure variability between and within individuals at work. In particular , few attempts have been made to discriminate between biological sources of variabilityand methodological uncertainty, including the effects of the EMG normalization procedure. The present study aimed to quantify the testretest repeatability of reference voluntary effort (R VE) contractions of the upper trapezius and the amount of variance introduced to EMG exposure parameters due to normalization trial variance.

    EMG data was collected from the right trapezius muscle of 15 female subjects during 36 work cycles of simulated industrial assembly work on t wo separate days. For all cycles, EMG was norrnalized to each of the four RVE calibration trials collected on the day. From the normalized data the following exposure parameters were calculated for all cycles and norrnalizations: 1 St, 10th, 50th, 90th, and 99th percentile APDF values; mean EMG amplitude; time spent at 'rest' « 6.7% RVE); and time spent at 'large activation levels' (> 100% RVE). Exposure variability due to subjects, day within subject, work cycle within day, and normalization trial was determined using a variance component analysis based on ANOV A algorithms. For all parameters, the dominate source of variance occurred between subjects. For all parameters, except the 1 st APDF percentile and the time spent at rest, the proportions of variance due to norrnalization and cycle were no more than 5% of the sum of all variance components. The betweenday variance for mean and all APDF parameters besides the 1 st APDF percentile ranged from 7 -19% of the total variance, indicating changes in work style or activation patters between days do exist. The effects of normalization reported here are likely at the low end of the range (test-retest coefficient of variation = 0.07) compared to the expected effects when data are collected in the field using less meticulously controIled RVE trials.

    Abstract

     

     

    Interest in Lean grows and spreads to the public from industrial and service sectors. Lean is currently used in administrative processes and it is called Administration but can administration be Lean? The aim of our study is to develop a useful model for a successful implementation of Lean Administration by using various scientific articles, books and information from the case study.

    The part of the purpose is to: • Identify critical success factors that arise• Identify the challenges arising from the implementation of Lean Administration.We have studied a Division within Distribution at GE Healthcare in Uppsala. The model that we have developed provides challenges and success factors for a successful implementation.

    In order to succeed in implementation, a culture that promotes continuous improvement must exist in the organization. A key success factor is to understand Lean Administrations structure and principles. Having a supportive leadership is a matter of course as well as having a secure and stable environment.

    Lean inom sjukvården2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [sv]

    Det är uppenbart för alla inom sjukvården i Gävle att de ligger på gränsen till vad de kan hantera. Landstingen bestämmer inte bara vad sjukvården skall producera, utan även vad det får kosta. Det går ibland inte ihop, vilket föder frustration och vanmakt hos berörda avdelningar och personal. Behovet av sjukvård kommer troligen att öka ytterligare i framtiden, och vi verkar ha kommit till vägens ände vad gäller nuvarande arbetssätt. Syfte och mål med detta examensarbete är att genomföra en förstudie till att implementera och arbeta med lean på Gävle sjukhus och ortopedavdelningen. Arbetet innefattar även att ta fram en generell arbetsmodell för att analysera och förbättra flöden inom sjukvården utifrån ett lean perspektiv. Examensarbetets olika moment har styrts utifrån gruppen framtagna modell. Nedan sammanfattas vilka moment som ingått i varje steg.

    1) Samla kunskap om lean: Första steget i arbetsmodellen handlar hur inlärning av lean i form av faktainsamling, litteraturstudier, föreläsningar och utbildning sker.

    2) Kartläggning av flödet: Andra steget behandlar kartläggning av det aktuella flödet från att patienten skadas i hemmet till att denna är färdigbehandlad. Vidare har intervjuer och observationer gjorts hos de olika avdelningarna inblandade i flödet parallellt med dokumentering.

    3) Analys av flödet i ett lean och kvalitetsperspektiv: Tredje steget innebär att en göra en analys av flödet med hjälp av olika metoder och verktyg inom lean.

    4) Förbättringsförslag: Fjärde steget innebär att med hjälp av analysen skapa förbättringsförslag på de problem organisationen identifierat i flödet.

    5) Implementering/Uppföljning: I sista steget handlar om hur en organisation inför förbättringsförslagen genom att informera och utbilda berörd personal.

    Några av de problem som upptäcktes under förstudien var långa väntetider till operation, överbeläggningar, dubbelarbete, bristande rutiner och kommunikation mellan avdelningarna. Efter insamlad information och sammanställning av intervjuer och problemformuleringar har gruppen kommit fram till en rad förbättringsförslag som anses relevanta vid implementering av lean.

    De olika lean och kvalitetsverktygen som gruppen främst har valt att jobba med är framtagna med hänsyn till de upptäckta problemen. Gruppens förslag till förbättringar inom det akuta höftflödet tror vi kommer förkorta vårdköerna, ge en mer kostnadseffektiv vård samt högre patient kvalitet. Lean har stor potential för sjukvården. Men att införa lean innebär inte enbart att införa en ny metod eller några verktyg. Det kräver en total förändring i synen på chefskap, på styrningen av sjukvården och på medarbetarnas roll. Förändringen sträcker sig ifrån högsta politiska nivå på landstingen till första linjens chefer som coachar sina team till dagliga förbättringar. Att införa lean är inte gjort i en handvändning, men det får inte hindra sjukvården ifrån att börja.

    Effektiv Planering enligt Lean Production: En fallstudie på Sandvik Mining and Construction2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    Due to a constantly increasing competitive pressure it is of great importance to constantly strive for improvements in order to gain competitive advantages. Lean Production is a concept that has been introduced with the aim to minimize waste and increase profitability. The purpose of this report is therefore to investigate how to perform effective planning according to the principles of Lean Production, in companys with customer exclusive products, through a case study at Sandvik Mining and Construction (SMC), and to investigate how SMC kan improve their planning of drifting rods at the production unit in Sandviken.

    The study started by creating a theoretical framework, to describe the subject planning and planning based on Lean Production. This frame work constituted the base for the case study which took place at Sandvik Mining and Construction, and also for the model and planning tool that has been introduced.

    The result of the study is partly a general model with factors that contribute to a more effective planning. These factors has beed identifed as SMED, which focuses on reducing set up times and in the end to facilitate the planning. With the assistance of the Pareto rule the amount of items can be grouped together and by that simplify production planning. By using the EOQ, optimized order quantities can be calculated, and thereby simplify for production planning. Even the degree of customer order management is something that affects how the planning can be managed as a high degree of customer order management can simplify for the decision making regarding wich product should be produced, however the time through production can increase. Sequensing is another method that simplifies the planning, as an already predetermined production order shall be produced. The most essential factor is however the motivation of the employees, as this forms the base to able other changes and implement them. Altogether these factors are closely connected to each other and working actively with these can contribute with a simplified planning procedure.

    From without this a tool has been presented in order to simplify the planning of drifting rods at Sandvik Mining and Construction. Through this tool SMC can create a smoother flow through production, a smoother work load, a smoother machine load in the different assembly lines, and in the end reduced adjustment times within the forging press.

    Abstract [en]

    A good work environment can support companies' competitiveness, but many managers mostly associate ergonomics with occupational health and safety. In the process of managing the work environment and creating a good working environment, company managers have a central role. This article investigated managers' own descriptions of the work environment management (WEM). The study group consisted of successful companies (n=142) in a county of Sweden. The managers' descriptions were categorised into nine categories. The most frequently described category was “PhysicalFactors at work”, followed by “Manuals and Standardisation”, and “EmployeeInvolvement and Interaction”.

    Framgångsfaktorer för arbete med funktionsöverskridande processer: En fallstudie vid Ericsson AB2008Independent thesis Basic level (degree of Bachelor), 10 points / 15 hpStudent thesis
    Abstract [en]

    A product often consists for the most part of purchased materials and to reduce the total cost of production, therefore, companies often focus on reducing their purchase prices. Pushing supplier prices in this way is a popular way to improve the company's short-term profits.

    Ericsson negotiates annually with its suppliers to reduce their purchase prices, which is considered to reduce purchasing costs and thus the production costs. This is achieved by the sourcing function in a process known as the VPA process. The VPA process requires information from the local supply functions, which, however, has no documented approach for these activities. The purpose of this study is, therefore, to create a support processes to sourcing VPA process. We have also from a theoretical approach critically reviewed the existing process.

    What we found is that Ericsson's approach could be sub optimized, focusing on achieving internal goals within the function creates obstacles for other functions. Often, if not always, each function focuses on its own goals and do not have a holistic view on organizational performance. This means that the organization as a whole may suffer when instead of optimizing process output, local optimization leads to total sub optimization.

    To prevent sub optimization, functions needs to create an understanding of the other functions goals, communication between the functions are therefore of critical nature. However, this is not enough, to reduce the focus on goals within functions and instead focus on process goals requires that senior management will create this opportunity.

    Leadership for Quality, Effectiveness and Health in Organisations2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Leadership, quality, effectiveness and health are important factors in the achievement of organisational success. Three questions are addressed to study these elements:

    1. How do leadership values relate to leadership behaviours, quality methodologies and health in organisations?

    2. How do leadership behaviours relate to effectiveness and health in organisations?

    3. How can leadership tools be designed and used to promote health in organisations?

    The research is based on five studies from three research projects. This research is reported in five papers. Study I concerned eight organisations in the middle of Sweden; the focus was on leadership values and behaviours. Study II concerned three successful organisations that received the award, ‘Sweden’s number one workplace’. Focus in this study was mainly on leadership behaviours. Study III combined results from Studies I and II with a focus on successful leadership behaviours. Study IV concerned the eight organisations in Study I. A leadership tool in the form of a Plan-Do-Study-Act (PDSA) model was developed and evaluated. Study V was of two organisations in Sweden; the focus in that work was on the use of a leadership tool control chart designed to give managers statistically valid early warning signals about health in their organisations. Theory X and Y together with the three-dimensional leadership behaviour theory were used to assess leadership values and behaviours. The theory surrounding PDSA and control charts were used to develop leadership tools. The dimension of health is defined from a salutogenic humanistic perspective; which emphasizes individual well-being. The dimension of quality is defined as the ability to satisfy or exceed needs and expectations. Effectiveness is defined as the extent to which externally and internally defined objectives are fulfilled.

    Both qualitative and quantitative research methods were used. Interviews, seminars with employees, collection of human resource and effectiveness figures, and questionnaires completed by managers and subordinates were used to collect data.

    Managers with more Theory Y-oriented leadership values were rated by subordinates as high concerning quality methodologies and leadership behaviour dimensions. The subordinates of these managers tended to be healthier.

    Two of the studies identified common groups of leadership behaviours in effective and healthy organisations: strategy and vision, communication and information, authority and responsibility, learning culture, worker conversations, plainness and simplicity, humanity and trust, walking around and reflective personal leadership.

    These leadership behaviours fit into a leadership profile where all three of the dimensions of structure, relation and change are present. Of the three, the relation dimension is strongest and concluded to be a universal dimension.

    The developed PDSA model seems to be a leadership tool that influences both leadership values and behaviour, particularly in the area of relation-oriented leadership behaviours. An early warning system built on CUSUM- and Shewhartcharts concerning the health indicators of self-assessed general health and new sickcases per employee was also found to be a powerful and usable leadership tool.

    For future research, the explorative research findings can be quantitatively tested using representative and preferably cross-national data, with a longitudinal design.

    Control charts as an early warning system for workplace health outcomes2011In: Work: A journal of Prevention, Assesment and rehabilitation, ISSN 1051-9815, E-ISSN 1875-9270, Vol. 39, no 4, p. 409-425Article in journal (Refereed)
    Abstract [en]

     Introduction: Statistical Process Control (SPC) charts have not been widely used to monitor workplace health and work environments. This research and effort to develop a more accurate and easy to use management control system for employee health is important from a humanistic, societal and economic standpoint, as well as complying with laws that regulate work environments. Objective: The purpose of the study is to design and discuss control charts as an early warning system for workplace health outcomes to promote workplace health management. Another purpose is to discuss relevant factors in the concept of the Out-of-Control Action Plan (OCAP) as a response when a chart warns that the workplace process may be malfunctioning. Participants: Two Swedish organizations were selected as case study organizations: a department at a university and an elderly care operation in a municipality. Methods: This study was explorative and should be seen as a starting point in learning how to use control charts for workplace health management. Self-assessed general health and new sick-cases per employee were selected as indicators for the control charts. Results: An integrated early warning system with Cumulative Sums-and Shewhart-charts are presented to show a possible method as to how an early warning system can be structured through the use of statistical control charts. Conclusions: The conclusion of this study is that control charts, along with well-designed implementation, make up a powerful and useable managerial early-warning system which promotes workplace health and helps to prevent sickness absence.

    Room acoustics and cognitive load when listening to speech2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The present thesis investigated the effects of background noise or a long reverberation time in learning situations. All studies used spoken texts that were presented above the speech intelligibility threshold, but were degraded enough to make listening more effortful. The basic hypothesis for the whole project was that listening to speech in a bad acoustic environment should increase the cognitive load for the listener, which should impair memory of the text. In Paper I the auditory stimuli were lists of words and sentences that were degraded by a background noise. Paper II was a replication of the experiment from paper I, but the independent variable was changed from the level of the background noise to reverberation time. Paper III included two experiments where the stimulus material was 10 minutes lectures.Paper IV included two studies. The first experiment investigated whether serial recall performance is affected when words are presented in long reverberation time (Exp 1a). In experiment 1b word lists were presented in long or short reverberation time or with a background noise. The stimuli were recorded in one classroom with extremely good and one with very bad acoustic design. In experiment 2 word lists with many or few phonological neighbours were presented with long or short reverberation time. In all studies some measure of working memory capacity was included. Taken together, the overall results could be summarized in two sentences: Hearing what is said is a necessary but not a sufficient criterion for people to remember what is said, which means that spoken information should be heard without special effort, otherwise proper learning is jeopardized. No consistent relation was found between working memory capacity and the learning effect in the unfavorable listening conditions.
