… setups, but requires shorter preparation for assembly. In the simulations the Wilson’s formula, Economic Part Period (EPP) and Least Cost method (LC) were compared with the lot-sizing model currently used by Uppåkra. The simulation results showed that there is a large potential …
… purchase quantities of assembling details and the LS:s are optimised with the Wilson- formula which here also pays attention to transport costs. With the MRP (material requirement planning) system the order points are received and they are formed by the safety inventories. The …
… De teoretiska modeller som har använts har varit ett säkerhetslagerteorem, Wilsonformeln och Maister och Zinns lagerreduceringsformel. Modellerna har knytigt samman empirin, analysen och slutsatsen till en sammanlänkande röd tråd, där möjligheten att ange sex stycken förslag på …
… of the way they now base the production plan on subjective estimations. With Wilson’s formula every article has been given an calculated optimal batch size to support the planning work. With subjective estimations there is a risk that wrong products are being produced during …
