摘要
针对大型相控阵雷达天线阵面视情维修与定期维修在维修时机上存在交叉的现象,将视情维修与定期维修相结合,提出了一种基于m/T维修策略大型相控阵雷达天线阵面备件优化配置模型。首先,在对m/T维修策略分析的基础上,建立了系统的使用可用度模型,并利用0-1分布对使用可用度进行了求解计算;然后,以使用可用度为约束条件,以LRU备件配置费用最小为优化目标,对大型相控阵雷达天线阵面备件配置进行了优化研究;最后,通过实例验证了该优化模型的有效性。
Aiming at the problem of time overlapping between condition-based maintenance and periodic maintenance of large phased array antenna, the m/T maintenance policy is put forward. Based on this maintenance policy, a system optimization model for spare parts is established. Firstly; a system operational availability model is set through analyzing the m/T maintenance policy; and the operational availability is calculated using 0-1 distribution law. Then, the optimization of spare-part configuration is studied by taking the operational availability as constraint condition and the configuration cost of LRU spare parts as optimization objective. Finally, the validity of the proposed maintenance and optimization model is verified by an example.
