摘要

Aiming at enhancing the mission reliability of complex systems composed of sequential-parallel parts, a sequential condition deterioration process model was constructed. To better illustrate the effect of varied maintenance behaviors, minimal maintenance, imperfect maintenance, and replacement were taken as optional maintenance actions and modeled. To achieve the maximization of current reliability, a selective maintenance decision-making model and the attached artificial solving measures were brought forward. The case study showed that by integrating the service age reduction model and hazard adjusting model, the imperfect maintenance model can model the actual reliability of the system better. Also, within a given maintenance time, imperfect maintenance was useful for offering more feasible maintenance plans, and the system reliability can be better promoted as a result.
