Abstract: To decrease the cost for preventive maintenance of single key parts in armament, the state of the parts was devided into several discrete states and their deterioration process was regarded as state transition. Some formulations were proposed to calculate the mean time interval, mean checking times, mean preventive maintenance times and average maintenance cost from the initial usage of the parts in good condition to one failure happened in the parts. Conditionbased preventive maintenance strategy optimization model was proposed aimed to minimize the average maintenance cost in a time unit. Experiments showed that the proposed methods could define routine checking interval and preventive maintenance state of the parts quickly and decreased the average cost in a time unit effectively.

Key words: conditionbased maintenance, strategy, optimization, single parts
