   Nyckelord :Nursing behaviour; suckling behaviour; sow welfare; piglet welfare; maternal behaviour;

   Sammanfattning : This master thesis aimed to investigate variation in the sow and piglet behaviour and welfare over time during a 5-week nursing period in the loose housing pen. This study was performed through analysis of video-recorded behaviours in 17 Swedish and Dutch Yorkshire sows and their piglets (284 piglets, pure-bred Yorkshire × Hampshire, average litter size with standard error = 16.

   Sammanfattning : Volvo Trucks is one of the world’s largest truck manufacturers, with a cab production plant located in Umeå, Sweden. The variation in batch sizes of the different components causes variation in the length of the production plan of subparts, and thus variation in production lead times. LÄS MER

5. 4. Investeringsbeslut kopplade till ställtidsreducering : En jämförelse mellan investeringsbeslut baserade på simulering respektive utan simulering

   Kandidat-uppsats, Högskolan i Jönköping/JTH, Maskinteknik; Högskolan i Jönköping/JTH, Industriell organisation och produktion

   Författare :Kristoffer Jernling; Erik Svensson; [2017]
   Nyckelord :ställtidsreducering; investeringsbeslut; simulering;

   Sammanfattning : Purpose - The purpose of this study is to investigate how the use of discrete event simulation affects investment decisions linked to changeover time reduction. This purpose has been met by answering the following two questions: • How does an investment analysis differ, regarding changeover time reduction, based on discrete event simulation from one that is not? • How is an investment decision in setup time reduction affected if the decision is based on discrete event simulation or not? Method - The study has been conducted as a one-off study at a Swedish manufacturing company where data collection has taken place through interviews and observations. LÄS MER
