Abstract:

This study evaluates alternative Selected Item Management SIMDemand-Based Item DBI criteria using historical demand data and a computer simulation model. The alternatives are evaluated in terms of 1 gross requisition effectiveness, 2 dollar investment in on-hand plus due-in stock and 3 volatility of the SIMDBI stock battery. Volatility refers to the size of the SIMDBI battery and to the rate of addsdeletes to the SIM battery. The study is based on historical demand data taken from six different types of ships FF, DD, LST, AD, LPD, and AFS. The objective of this study is to evaluate various SIMDBI qualifying and retention criteria and to determine which criteria best minimizes dollar investment without any loss of effectiveness. The SIMDBI criteria of two demands in six months to qualify and one demand in six months to remain a part of the SIMDBI stock record battery was considered the benchmark for this study. The SIMDBI benchmark generally had the highest gross effectiveness, dollar investment, resupply orders, and volatility for each test ship. This study showed that there was no single policy which was best for all ships.
