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.
