In view of the limitations that the optimal examining items do not have dynamic and real-time performance in the traditional Preventive Maintenance (PM) model of repairable devices, a dynamic and real-time control strategy that selecting checking rate as control variable to control the dynamic behaviour of maintenance system is proposed based on the actual state of devices. The mathematical model of maintenance system is established, some performance indexes of maintenance system including the steady-state availability and the Mean Time To Failure (MTTF) are calculated. And then the control laws on the checking rate are designed. In the end, devices state evaluation is performed and the control errors and the selection of control timing are analyzed and given out. The essence of the strategy proposed in this paper is to achieve the expected steady-state behaviour by controlling the dynamic behavior of maintenance system and reduce the possibility of corrective maintenance by modifying MTTF of maintenance system, which will guarantee reliable completion of target task and reduce maintenance cost. Researches indicate that the strategy proposed in this paper is very effective to improve the utilization of devices and guide the maintenance practice activities of enterprises.
