Abstract: In many industrial and military environments, systems are required to execute a sequence of missions with a finite break between every two adjacent missions. During a break, failed or aged components can be repaired to ensure the success of the subsequent missions. However, due to limited maintenance resources, such as budget, time, manpower, and repair facilities, it is usually impossible to perform all the desirable maintenance actions in each break. Under such a circumstance, selective maintenance, as a particular maintenance strategy, can be implemented to identify a subset of feasible maintenance actions among all the feasible maintenance actions to ensure the success of the subsequent missions. In this paper, the definition and basic model of selective maintenance are presented. Diverse selective maintenance strategies from various perspectives are summarized. The challenges and prospective directions for further research are also discussed.

Key words: selective maintenance, maintenance optimization, limited maintenance resources
