摘要
为了解决任意备件条件下k/n系统的维修问题,提出一种(s,c,m,T,r)维修策略,建立了在该维修策略下系统的使用可用度模型以及维修费用模型。结合系统维修需求及实际情况,以使用可用度最大、单位时间维修费用最小作为优化目标,建立了k/n系统的多目标维修优化模型。设计了一种基于遗传算法的模型求解算法,利用该算法可以得到多种维修方案,为维修决策者提供参考。以某单位相控阵雷达天线阵面维修为例,借助模型算法得到了具体的维修方案。
To solve the maintenance problems of k/n system with random spares,a maintenance policy named(s,c,m,T,r)was proposed.Firstly,both operational availability model and maintenance costs model were built in the proposed maintenance policy.Secondly,a multi-objective optimal maintenance model by taking the maximum operational availability and the minimum maintenance costs per unit as the optimization objectives was built.And then a solution algorithm based on genetic algorithm was designed to get multiple maintenance plans which offer a reference to the maintenance decision maker.Finally,through the proposed optimal maintenance model,some specific maintenance plans of the maintenance of the phased array radar antennas in one radar troop were obtained.
