Abstract

This paper investigates the optimal maintenance strategies for a self-repairable component under detection at fixed time intervals. The failure process of a component is considered as two parallel and competing degradation processes: an internal degradation process and an external shock degradation process. Unscheduled maintenance from unofficial sources after each shock to a component is regarded as a self-repairable behavior of the component, and its effectiveness is well evaluated. The official maintenances are preventive maintenance (PM) and corrective maintenance (CM), and two thresholds are set based on reliability values to represent the minimum points for performing PM and CM, respectively. The approximately optimal PM and CM thresholds are found by minimizing the overall maintenance cost rate of a component over a specified operating time. Finally, we demonstrate the feasibility of the model through a numerical case study, give a summary, and suggest possible future research directions.
