Pacific Fleet Regional Inventory Stocking Model (PRISM)

摘要

This following project describes and assesses the current inventory stocking tool used by Commander U.S. Submarine Force Pacific Fleet (CSP), Mission Essential Spare Support (MESS), to manage its SSN stocking levels during a deployment work-up period. We also introduce a proposed demand based inventory management tool, Pacific Regional Inventory Stocking Model (PRISM), and compare it with the tools currently being used within CSP. This analysis will then evaluate the effectiveness of each system as a management tool using data from CSP's SSN-688 Fast-Attack Submarines. The decision criteria estimated are operational readiness and associated inventory costs. Statistical simulation modeling will be employed to compare these evaluated criteria as determined by MESS and PRISM. This analysis provides evidence that with the inclusion of repair part demand data, cost savings will be realized for a specified inventory service level. Recommendations will be provided, based on the results of the comparison, as to the feasibility of implementing PRISM, maintaining MESS, or developing a new submarine stocking system to replace the status quo.
