考虑串件拼修的k/N系统批量备件配置方法

Optimal Configuration Method of Block Spare Parts for k/N Systems Considering Cannibalization

针对k/N系统批量备件的配置问题,提出一种视情维修条件下考虑串件拼修的备件优化配置方法。建立了基于串拼修复率和SRU更换率的系统级备件满足率模型,给出了串拼修复率和SRU更换率的约束条件。以备件配置费用最小为目标、以系统备件满足率为约束条件建立了系统备件的优化配置模型,设计了一种基于边际效益分析法的模型求解算法。以某型大型相控阵天线阵面备件配置为例,利用定量和比较的仿真分析方法对提出的模型进行了验证,得到了备件的优化配置结果。结果表明:提出的模型真实有效、可行性强,为进一步研究k/N系统批量备件的配置问题提供了理论支持。

Aiming at the configuration problem of block spare parts in k/N systems, an optimal configuration method of block spare parts considering cannibalization and on-condition maintenance was proposed. A spare parts fill rate model for k/N systems was established on the basis of two parameters named cannibalization rate and SRU replacement rate, and the constraint conditions of both the parameters were given respectively. An optimal configuration model was built, which chose the minimum spare costs as the object and the spare fill rate as the subject, and a model solution algorithm based on the margin analysis theory was given. Simulations and analysis were conducted by taking the spare parts configuration problem of one large-scale phased array antenna as an instance, and the optimal results were achieved through the simulation methods of quantitative and comparative analysis. The results show that the presented model is of high validity and feasibility, and can provide theoretical support for the deeply research on the block spare parts configuration problems for k/N systems.
