摘要

This report compares the cost and stockage of a War Readiness Spares Kit (WRSK) computed using the Dyna-METRIC model to a WRSK computed using a modified Dyna-METRIC model. The modified Dyna-METRIC model finds the least cost mix of line replaceable units and shop replaceable units required to meet the wartime weapon system performance objective. The unmodified Dyna-METRIC model computes Remove, Repair, and Replace (RRR) WRSK that provide equal combat capability at $.76 million to $3.46 million less cost than the (unmodified) Dyna-METRIC model. Generally this requirement cost savings is attained because the modified Dyna-METRIC stocks fewer line replaceable units and more lower cost shop replaceable units. The modified Dyna-METRIC model also provides the capability to compute the spares needed to maximize combat capability given a funding limitation. The Air Force Logistics Command intends to implement the modified Dyna-METRIC model in the Weapon System Management Information System (WSMIS) Requirements Execution Availability Logistics Module (REALM).
