Contents I. Introduction
AS an important part of the modern logistics system, AS/RS is a multi-layer elevated warehouse system. It has integrated computer information management and the equipment control. The high efficiency of the AS/RS is based on efficient storage location management. To manage the storage location is to assign and use the storage location reasonably. We need not only to consider how to improve the utilization of the storage location, but also to guarantee the unloading efficiency. Storage location assignment includes two aspects: one is to assign the optimum storage location for the materials to be loaded, which is loading storage location assignment; the other is to select the storage location of materials to be unloaded [1]. Just basing on this thought, the paper optimizes and simulates the storage location assignment combined with Flexsim logistics simulation software and so as to provide theoretical basis for improving the loading-unloading efficiency.
