Abstract [en]

This thesis evaluates the product to product changeover process of the line S10 at the Coca-Cola European Partners manufacturing plant in Jordbro, Sweden. The target has been to propose improvements to reduce the total planned downtime by 10%. The total planned downtime in March of 2019 was 4449 minutes. Secondary data has been used to identify the current situation. A study visit took place at the Coca-Cola European partners manufacturing facility in Dongen, the Netherlands, to serveas inspiration. Single Minute Exchange of Dye (SMED) methodology was applied to improve the most frequent planned downtime event (PDT event), which was performed 22 times during March of 2019 at an average of 72,8 minutes. The theoretical improvement for PDT event CIP programme 1, by applying SMED methodology, is estimated to roughly 16 minutes. This theoretically saves 8% of the total planned downtime for March of 2019. The same solutions from the SMED methodology could be applied to other PDT events, which would increase the number of events from 22 to 27. This would theoretical save 9,6 % of planned downtime for March of 2019.

Abstract [sv]

Det här examensarbetet utvärderar produktomställningsprocessen på linjen S10 som vid Coca-Cola European Partners produktionsanläggning i Jordbro, Sverige. Målet har varit att föreslå lösningar som reducerar den totala ställtiden med 10%. Den totala ställtiden för mars 2019 var 4449 minuter. Sekundärdata har använts för att identifiera nuläget. Ett studiebesök utfördes hos Coca-Cola European Partners produktionsanläggning i Dongen, Nederländerna, för att inspirera möjliga lösningar. Single Minute Exchange of Dye (SMED) metodologi tillämpades för att förbättra den mest frekventa omställningsprocessen, som utfördes 22 gånger under mars 2019 med en genomsnittlig ställtid på 72,8 minuter. Den teoretiska förbättringen av omställningsprocessen CIP program 1, med hjälp av SMED metodologi, uppskattas till ungefärligt 16 minuter. Detta reducerar den totala ställtiden för mars 2019 teoretiskt med 8%. Samma lösningsförslag från SMED metodologin skulle kunna tillämpas på andra omställningsprocesser, vilket skulle öka antal processer från 22 till 27. Teoretiskt sätt skulle detta reducera den totala ställtiden för mars 2019 med 9,6%.
