GPSS study of Work-In-Process inventory

摘要

This paper reviews the use of two GPSS models to verify effects of changes in an inventory control system. Selected model output, general descriptions of the models, summarization of output and discussion of results are included. The GPSS models were essentially inventory models which determined the work-in-process inventory (WIP) variations under two different methods of controlling and disbursing a high cost inventory item. Reductions in the amount of WIP required to meet production, control of WIP and amount of exposure to inventory obsolescence were measured by the GPSS models.
