Submarines and Submarine Tenders Demand-Based Policy Study

摘要

This study evaluates alternative Selected Item Management (SIM)/Demand-Based Item (DBI) criteria for submarines and submarine tenders using a computer simulation and historical demand data. The alternatives are evaluated in terms of: gross requisition effectiveness; dollar investment in on-hand plus due-in stock; workload (the number of resupply orders); and volatility of the SIM/DBI stock battery. Volatility refers to the size of the SIM/DBI battery and to the rate of adds/deletes to the stock battery. The objective of this study was to evaluate various SIM/DBI qualifying and retention criteria based on supply effectiveness, investment, workload, and volatility for submarines and submarine tenders.
