基于体系保障度的装备备件三级库存方案优化

三级维修供应管理是部队较为常见的保障模式, 备件库存方案是影响装备系统可用度的关键因素之一. 装备保障性工程中的实际问题出发, 在考虑备件结构层级的情况下, 根据METRIC基本原理, 建立了系统备件的三级保障评估模型, 将三级体系保障度作为优化指标函数, 以保障费用为约束条件, 运用边际优化方法对备件方案进行优化. 通过实例给出了备件的最优库存方案结果, 得到了备件三级库存配置的一般规律, 并分析了影响备件库存分配的各种保障性因素. 优化结果符合具有三级供应保障机制下的备件配置规律, 能够为部队保障人员制定备件方案提供一定的决策依据.

Optimization of three-echelon inventory project for equipment spare parts based on system support degree

Management of three-echelon maintenance and supply is a common support mode,in which the spare parts inventory project is one of the critical factors for system availability.Focus on the actual problem of the equipment support engineering,the system spare parts are divided into two levels,and based on the METRIC theory,the three-echelon support evaluation model for system spare parts is established. The three-echelon system support degree is used as the optimization target while the cost is taken as the restriction,and the margin analysis method is applied to inventory project optimization.In a given example,the optimal inventory project and the distribution rule for spare parts is got,and the influencing factors for spare parts inventory is analyzed.The optimization result is consistent with the basic principle under the three-echelon support pattern,which can supply decision assistance for equipment support personal to design a reasonable project.
