Abstract: A sequential condition deterioration process model is constructed to enhance the mission reliability of complex systems composed of sequential-parallel parts. To better illustrate the effect of varied maintenance behaviors, the minimal maintenance, imperfect maintenance and replacement are taken as optional maintenance actions and modeled. A selective maintenance decision-making model and the attached artificial solving measures are presented to maximize the current mission reliability. The result shows that the imperfect maintenance model can be used to represent the actual reliability of the system better by integrating service age reduction model and risk correction model. Also within given maintenance time, the imperfect maintenance strategy is of help to offer a more feasible maintenance plan and increase the system reliability. Key
