以长期运行费用率为评估指标，研究了劣化系统的周期预防性维修策略。假定开展的周期预防性维修介于最小维修和完全维修之间，维修间隔期间的故障过程用非齐次泊松过程进行描述，在此基础上采用比例寿命回退模型对预防性维修效果进行建模，给出了最佳预防性维修周期 T 和预防性维修次数 N 的计算方法以及参数应当满足的条件，同时结合实际情况给出了（N ，T）策略的优化求解算法，最后通过数值算例，验证了所提方法的可行性。

The periodic preventive maintenance policy for a deteriorating repairable system is studied.Pre-ventive maintenance actions restore the system to a condition between as good as new and as bad as immediately before the maintenance action.The breakdown process during the preventive maintenance actions is supposed to follow a nonhomogeneous Poisson process.The proportional age setback model is used to measure the quality of the maintenance actions.The expressions for the optimal preventive maintenance period T and the count of pre-ventive actions N are derived.Conditions are given under which a unique optimal policy exists.A practical algo-rithm is proposed to get the optimal (N ,T)policy.Numerical examples validate the algorithm.
