摘　　要：针对相控阵天线阵面备件配置存在的冗余性强、批量送修、多级维修等现实问题,综合考虑备件费用、维修能力以及库存策略之间的关系,建立了基于定期补给的两级备件优化配置模型。给出了系统的故障件维修周转过程和维修备件的定期补给过程,在分析备件、库存、维修能力之间关系的基础上,结合成批到达的排队理论,建立了系统的供应可用度模型。以备件配置费用最小为目标、以系统供应可用度为约束条件,建立了系统的备件优化配置模型,并通过边际效益分析法对模型进行了求解。通过算例仿真与分析对模型进行了验证。结果表明:构建的备件配置能够较好地解决相控阵天线阵面的备件配置问题,具有一定的优越性。Three problems are normally found in the spare parts configuration of phased array antenna, namely, the strong redundancy, the batch delivery maintenance and the multi-echelon maintenance. Aiming at these problems, through analyzing the relations among spare parts cost, repair capacity and inventory strategies, an optimal configuration model was established based on the periodic review strategies. Firstly, the repair circulation process of fault component and the periodic supply process of maintenance spare parts were given, and then the system supply availability model was built by analyzing the relations among spare parts, inventories and repair capacity, and the batch arrival queuing theory was also used. Secondly, an optimal configuration model of spare parts was built, which takes minimum spare parts costs as the object and the system availability as the subject. Next, solution algorithm based on the margin analysis theory to the model was also given. Finally, simulations and analysis of an instance were conducted to verify the proposed model, and results show that the model can solve the spare parts allocation problems of phased array antenna well, and has a high superiority. 
