Generic simulation model for assembly line supply

In this paper a simulation model for materials supply to mixed-model assembly lines is discussed. The model is created in FlexSim and demonstrates the in-plant logistical flows involved to supply parts from the warehouse to the use-points at the assembly line. The materials supply methods shown are bulk feeding (also referred to as line stocking) and kitting. The results of the simulation model are compared to the results of a deterministic mathematical cost model to study the impact of real production variations and dynamics. Testing is done based on a case study where 438 parts are supplied to 23 work stations o of which 146 are supplied in bulk, while the remaining parts are kitted. To create this specific model an automatic model generator is used. The findings of this study are reported
