Simulation of an automated stacker storage system

摘要

The Management Sciences Department at Philips Morris has been investigating areas of optimazation within the Finished Goods Warehouse. In pursuing these studies, simulation models have been used as analytical tools. For modelling, GASP IV Simulation Language was selected since it provides exceptional flexibility.

The most recently developed model simulates operations of the automated stacker storage and retrieval system. Through analysis of model behavior, Management Sciences evaluates a variety of algorithms. Concepts such as surge controlled interleaving, zones based on turnover, and load leveling have been tested.

After determining which algorithms provide the greatest efficiency, Management Sciences submits reports to appropriate managers. Additional studies are being accomplished by analyzing model behavior at higher production levels to identify system bottlenecks.
