面向动态任务的作战单元两等级两层级可修复备件优化

针对作战单元执行任务前备件保障方案制定难的问题，在对作战任务和备件保障系统分析的基础上，对可修复备件控制多级技术（multi-echelon technique for recoverable item control, METRIC）经典模型进行了扩展，提出了作战任务和保障能力动态变化条件下的作战单元两等级两层级任务成功性评估模型。以备件购置费用为优化目标函数，作战单元任务成功性为约束条件，建立了基于作战单元任务成功性的备件优化模型，运用边际效应方法给出了优化模型的求解方法。通过应用实例给出了相应的备件优化方案和优化备件方案下的作战单元任务成功性评估曲线。该模型可为装备保障指挥人员根据作战任务和保障环境制定备件保障方案提供一定的决策支持。

Dynamic mission-oriented two-echelon and two-indenture repairable spare parts optimization for combat units

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.
