摘　　要：为在有限保障经费下提高装备的供应可用度,需要对备件的库存与订购策略进行优化。对随机需求下的可修件和不可修件分别给出了期望缺货数的计算方法,从而获得单个部件可用度和保障费用的计算模型;对于可以分解为多个层级、由多种类型部件构成的装备,给出了其可用度的计算模型;利用边际效应法,分层级将可修件的库存分配、不可修件的订购策略结合在一起进行优化,获得了完整的保障方案,并得出多层级装备的保障费用—效能曲线;给出实例对模型与算法进行了验证。The stock and order policy of spare parts influences the availability of equipment.A method was proposed to calculate the expected number of backorders for both repairable and discardable units for the availability of a single part.A model was established to analyze and calculate the availability of multi-echelon equipment.Then the stock and order policies of spare parts were combined and optimized one echelon after another by using the marginal effect,and an entire support plan was got after the optimization.Furthermore,the cost-effective curve of multi-echelon equipment was obtained.An example was given.
