摘　　要：对可维修备件维修保障的军事背景进行了描述。研究了可维修备件单级库存系统;建立了具有紧急供应策略和无紧急供应策略的单级库存模型。在紧急供应库存模型中,利用M/M/k损失模型确定了备件需求通过紧急供应满足的概率和备件期望库存水平;在正常供应模型中利用帕尔姆定理确定备件期望库存水平。设计了简单高效的贪婪算法求解模型的最优解,给出了具体算例。The military background of maintenance and support of the complex equipment was described.A single echelon inventory system was investigated;the single echelon inventory models,which have emergency supply strategy and regular supply strategy,were established.In model of emergency supply,M/M/k loss model was used to evaluate the fraction of demand satisfied by emergency supply and expected inventory of repairable parts;in model of regular supply,Palm theorem was used to evaluate expected inventory of repairable parts.The optimum solution of the inventory model was determined by the designed simple and efficient greedy algorithm.The specific example was solved by the model and the algorithm.
