Abstract [sv]

Detta examensarbete är utfört på Scania Södertälje i syftet att kartlägga cykeltider av Kärnamakeri avdelning på nya gjuteriet. Mätning alla av cykeltider för att sen kartläggas görs för att tydligt visualisera utrustnings samt avdelnings kapacitet. Projektet inleddes med insamling av all nödvändig information som underlag för genomförande av arbetet och därefter valdes lämpliga metoder för att uppnå målen.

Resultatet visar en berglipig cykeltidskartläggning över hela avdelningen med en tydlig identifiering av flaskhalsarna som styr hela produktionen. Med hjälp av den valda metoden analyserades flaskhalsarna djupnade för att hitta möjliga slöserier i form av onödiga rörelser för att utföra processen.

Förbättringsförslag presenterades som avslutning del av projektens resultat samt även som rekommendationer för fortsatt förbättringsarbete att optimera produktionskapacitet.

Abstract [en]

This thesis project is implemented at Scania Södertälje with the aim of mapping cycle times of the core making department at the new foundry. All measurement of cycle times to then be mapped is done to clearly visualize equipment and department capacity. The project began with the collection of all necessary information as a basis for carrying out the work and then suitable methods were chosen to achieve the goals.

The result shows a pronounced cycle time mapping across the entire department with a clear identification of the bottlenecks that control the entire production. Using the chosen method, the bottlenecks were analysed in depth to find possible waste in the form of unnecessary movements to carry out the process.

Improvement proposals were presented as a concluding part of the project's results and also as recommendations for continued improvement work to optimize production capacity.
