摘要： 基于退化状态影响退化速率的交互模式和分级交互思想，建立多部件动态退化交互模型；引入基于交互系统整体退化状态的变周期检测机制，并从维护延缓相关部件短期退化交互速率的视角出发，以单位时间总维护成本最低为目标，构建考虑变周期检测和修复非新的多部件退化交互系统机会维护动态决策模型.算例分析表明，该动态维护模型具备成本优势.

Abstract: Based on the idea of state-rate degradation interaction and state discretization, a multi-component dynamic degradation interaction model is established. Besides, a non-periodic inspection policy is introduced based on the overall degradation condition of the interaction system. Moreover, from the perspective of maintenance, which can decrease the short-term interacted degradation rate of the related components, a dynamic opportunistic maintenance model is established with the goal of minimum maintenance cost per unit time. Furthermore, the non-periodic inspection policy and imperfect preventive maintenance actions are designed as well. The case study shows that the proposed model has cost advantages.
Key words: opportunistic maintenance; degradation interaction; multi-component system
