Abstract:

The problem that spare parts concept is difficult to make before combat mission is considered. Combat unit mission and the support system of spare parts are analyzed. The classical multi-echelon technique for recoverable item control (METRIC) model is extended and a combat unit mission success evaluation model with two-echelon and two-indenture support system for dynamic mission and support ability is proposed. Stock cost is taken as the optimization object and combat unit mission success parameter is used as the restriction. Based on a margin analysis method, the computation method for spare parts optimization is provided. An applying example is analyzed. The optimized spare parts concept and the mission success evaluation curve with the concept are provided. That model would the help equipment support commander make support decision in support concept design aiming at combat mission and support environment.
