| Abstract | For large and complex systems, scholars proposed the periodic replacement policy with minimal repair. The policy is further investigated with the allowed number of intervening repairs (failures) before replacement, which is similar to the notion of periodic replacement. However, the maintenance policy cannot be executed when a product is performing a timespanning mission. This will consequently create uncertainty in the number of planned failures. In this study, an appropriate replacement policy that considers the number of repairs and the duration of mission is proposed to guarantee the required reliability and maintainability of a system. The optimal number of planned repairs is obtained analytically under the given mission duration. Numerical examples show that the suggested models in this study can provide better guidance for the maintenance of practical systems.
