Abstract A break between successive missions provides opportunity to perform maintenance on the system. However, limited resources, e.g., time, budget etc., may not allow performing all possible maintenance actions on the system. A subset of maintenance actions are then selected from the available maintenance options such that the system can meet the next mission requirement. This maintenance policy is called selective maintenance. A system subjected to the two types of failure modes is studied in this paper. These modes are the maintainable and the non-maintainable failure modes. An age-based imperfect maintenance policy is used for the maintainable failure modes. The maintainable failure modes also depend on the cumulative effect of the non-maintainable failure modes. Maintenance decision is made such that the system reliability during the next mission is maximized under the budget and time constraints. The differential evolution (DE) is used to find the final solution.
