摘　　要：现阶段对于大型相控阵雷达T/R组件何时开展换件维修、维修时全部更换故障组件还是部分更换、备件数量如何配置等有关问题还没有一个具体标准,开展T/R组件维修决策问题研究可为装备保障人员提供维修决策支持。首先,对T/R组件维修决策的主要内容进行阐述界定。其次,分别从故障数据预测、故障寿命分布、基于故障数据的设备性能评估3个方面对故障数据建模研究现状进行分析。然后,从维修策略类型和维修策略优化模型两个方面重点对维修策略进行阐述,并对以可用度、备件满足率、备件期望短缺数、任务成功率等为决策变量的备件库存策略进行分析。最后,分析了现有方法存在的不足,提出T/R组件维修决策需要解决的上述3个重要问题,为后续研究提供理论支撑。At this stage, there is no specific standard on when to replace the T/R module of large-scale phased array radar, whether to replace all or part of the faulty module during maintenance, and how to configure the number of spare parts. The research on the maintenance decision of T/R module can provide maintenance decision support for equipment support personnel. Firstly, the main contents of T/R module maintenance decision are described and defined. Secondly, the research status of failure data modeling is analyzed from three aspects: failure data prediction, failure life distribution and equipment performance evaluation based on fault data. Then, it focuses on the maintenance strategy from two aspects: the type of maintenance strategy and the optimization model of maintenance strategy, and analyzes the spare parts inventory strategy with availability, spare parts satisfaction rate, expected shortage of spare parts and task success rate as decision variables. Finally, the shortcomings of existing methods are analyzed, and the above three important problems to be solved in T/R module maintenance decision-making are put forward to provide theoretical support for follow-up research.
