摘要
In general, the dependent failure among different components is considered in maintenance decision of the complex multi-component system. The degradation process analysis model of the degradation interaction multi-componerit system is built considering the degradation rate of one component is affected by the degradation levels of dependent components. On the basis of non-decreasing degradation assumption, the reliability functions of the system and components are derived. Then, the preventive maintenance policy for different component types is put forward, and the maintenance decision model with the goal of minimal per unit cost is built. Finally, taking a two-component system as an example, the accuracy of proposed reliability models is examined, and the optimal preventive maintenance policy for the system is derived, which verifies the reasonability and effectiveness of the maintenance decision model. © 2018, Editorial Office of Systems Engineering and Electronics.
