Comparison of Two Systems for Distributing Spare Parts

摘要

The Air Force and Repair in Variable Environment (DRIVE) model is designed as animprovement over the Uniform Materiel Movement and Issue Priority System (UMMIPS) in the wholesale-to-retail distribution of reparable spare parts. This report describes and quantifies the possible improvements achieved when DRIVE is used. The principal benefit offered the DRIVE is the ability to determine precisely and accurately the Air Force unit that has the 'greatest need' for an item. That greatest is based on current best estimates for the unit's peacetime and wartime demands and projected assets and the peacetime and wartime availability goals specified by operational commanders. This report quantifies benefits of the Air Force's current concept of operations (CONOPS) for implementing Drive. It also demonstrates how a modified 'push' DRIVE allocation system could provide significant improvements over the current DRIVE CONOPS and identifies follow-on efforts that will help bring the Air Forces closer to extracting the maximum benefits from the DRIVE program.
