Abstract [sv]

Emballagefabriken tillverkar förpackningslösningar i form av trä- och plywoodlådor. Låg lönsamhet råder på företagets manuella monteringsavdelning på grund av lång genomloppstid vid tillverkning av produkten Plywoodlådan. Tillverkningen sker i fyra steg och börjar vid sågavdelningen följt av tryckeriet sedan cnc-avdelningen och till sist monteringen. Syftet med arbete var att reducera de icke värdeskapande aktiviteterna som uppstod i produktionsflödet.

För att få en överblick av nuläget genomfördes en materialflödesanalys följt av en förstudie, som identifierade vilka aktiviteter som utfördes på respektive avdelning. Med detta som bakgrund genomfördes kvantitativa tidsstudier av aktiviteterna parallellt med kvalitativa observationer. Slutligen klassificerades samtliga aktiviteter med hjälp av produktionspersonal och produktionschefen.

Tidsstudierna resulterade i en kartläggning av de icke värdeskapande aktiviteterna, som sedan analyserades. Slutligen togs förbättringsförslag fram som företaget kan implementera.

Slutsatsen av arbetet visade att det fanns potential att reducera, och i vissa fall eliminera de icke värdeskapande aktiviteterna.

Abstract [en]

Emballagefabriken manufactures packaging solutions made of wood and plywood. Low profitability prevails on the manual assembly department of the company, due to a long throughput time in the manufacture of the Plywood box. The production is performed in four steps and begins at the saw department followed by the printing department, then the cnc department and finally the assembly. The purpose of this work was to reduce the non-value-added activities that occurred in the production flow.

To get an overview of the current situation, a material flow analysis was performed followed by a preliminary study that identified which activities were performed in each department. With this in mind, quantitative time studies of activities were conducted in parallel with qualitative observa-tions. Finally, all activities were classified in cooperation with production staff and production manager.

The time studies resulted in a mapping of non-value-added activities, which were then analyzed. Finally, improvement proposals were put forward that the company could implement.

The conclusion of the work showed that there was potential to reduce, and in some cases eliminate, non-value-adding activities.
