研究了修理工带有多重休假且定期检测的累积冲击模型。为了延长系统的运行时间，在检测时考虑了预防维修。将事后维修和预防维修结合起来运用于可修系统，且假定预防维修能够“修复如新”，而事后维修为“修复非新”。以系统的检测周期和故障次数为二维决策变量，选取系统经长期运行单位时间内期望费用为目标函数。并通过数值分析，求出了最优策略。

This paper studied a cumulative shock model of a repairman with multiple vacations and periodic inspection. In order to prolong the running time of the system,preventive repair should be considered during the inspection time,and breakdown maintenance be connected with preventive repair in repairable system,assuming that preventive repair can be “as good as new”,while breakdown maintenance is not “as good as new”.The two-dimensional decision variables were based on the periodic inspection and the failure number,and the expected cost of the long-running unit time was selected as the obj ective function.And the optimal policy was obtained through numerical analysis.
