Summary:The maintenance decision needs to consider various aspects such as cost, safety, system condition etc. This paper presents a condition-based maintenance optimization model with a risk acceptance criterion under imperfect inspection. The inspection interval can adaptively change with the system condition. In order to make the maintenance decision more reasonable, the optimization model, which minimizes the expected long-term cost rate with safety constraints, also considers the influence of imperfect inspection. The method is illustrated through the case of a feeder pipe of a nuclear power plant. The results show that the safety constraint and measurement error cannot be ignored.
