摘　　要：装备备件配置方案是装备综合保障领域需要解决的关键问题之一,提高备件满足率能够相应地提高系统的可用度,从而提高装备的保障度。针对这一问题,文章从装备可用度为出发点,分析了装备可用度与系统备件满足率之间的关系,建立了任意结构系统的备件满足率模型。建立的模型通用性较强,适用于任何结构的复杂系统。综合权衡备件满足率与备件费用之间的关系,采用边际效应方法对备件配置方案进行优化,得到最优的备件配置方案。通过对实例运算结果的分析,证明了所建模型的正确性与合理性。The equipment spare part collocation project is one of a critical problem to be solved for equipment support,improving the spare part sufficiency can boost the system＇s availability,thus improving the support degree of equipment.Aiming at this problem,the relation between the equipment availability and the system＇s spare part fill rate is discussed,and the model of the spare part fill rate for various structures systems is established.The spare part model has a good performance of generality,which can be applied to complex system with any structure.In order to balance the spare part＇s cost and fill rate,the margin analysis theory is used to optimize the spare part＇s collocation project,through which the optimum project can be gained.Through the analysis to the calculation result,the correctness and rationality of the model are proved.
