Abstract
In recent years many OEMs especially in the automotive industry have installed socalled supermarkets on their shopfloors to feed parts to assembly lines in a flexible and justintime manner Supermarkets are small logistics areas within the factory where parts are intermediately stored to be transferred often in the form of presorted kits to nearby workstations frequently and in small lots While this greatly alleviates inventory concerns at the assembly line care must be taken that the supermarket itself always be adequately stocked In this paper we tackle the problem of determining when which part types should be taken from central receiving storage to the supermarket in what quantities such that on the one hand shopfloor traffic remains manageable while on the other hand inventory costs are not excessive We formalize the problem investigate the computational complexity and develop a bounding procedure as well as a heuristic decomposition approach Computational tests show that our procedures work very well on instances of realistic size Moreover we study the tradeoff inherent in the problem between delivery frequency and inprocess inventory
