摘　　要：备件横向转运补给能有效提高装备保障效能,针对现有研究不适应装备复杂的层次结构关系,以及未考虑不完全修复件的报废情况等问题,建立了多等级、多层级下不完全修复件的库存横向转运模型,模型的正确性通过仿真得到了验证。在此基础上首先以装备可用度为约束,以备件购置费用最低为目标,利用边际优化算法得到备件初始配置方案;然后,在考虑备件报废率的情况下,通过权衡订购费用与库存管理费用得到备件后续采购方案;最后在实际案例中,通过与非转运条件下的优化方案比较,验证了转运策略在提高装备保障效能方面的作用。The ordering of imperfect repairable spare parts supplied with lateral transshipments is an effective approach to improve support effectiveness of equipment. Since the existing researches do not meet the demands of complex hierarchical structure of equipment in army or do not consider the discard of imperfect repairable spare parts, an inventory model considering multi-echelon support system for multi-level equipment with lateral transshipments is built and the simulation shows that the model produces accurate estimation. With constraints of equipment availability and objective of the lowest cost of spare parts, the optimal initial inventory distribution of spare parts is obtained by marginal optimization algorithm. With the consideration of discard spare parts, the follow-up ordering project is got by judging the ordering and holding costs. Compared with the model without transshipments, numerical study shows that policy of transshipments plays an important role in improving support effectiveness of equipment.
