本文考虑了一个带一般修理的周期更换问题，其中系统只在预定的时刻kT（k = 0，1，.）被更换，并且在系统发生故障时被修理.所谓一般修复，我们指的是修复使系统的状态达到某种更好的状态。建立了一个描述可修系统在一般维修下按时间运行的随机模型。该模型包含最小修复的情况下，修复恢复系统的功能条件之前，故障。更换政策下的一般维修推导出最小维修假设的敏感性进行了数值研究。可以看出，政策是不敏感的，当系统的恶化速度不快，更换成本相对于维修成本高。最低限度的维修假设，然后证明这种情况下。
In this paper, a periodical replacement problem with a general repair is considered where a system is replaced at only scheduled timeskT(k = 0,1,…) and is repaired whenever it fails. By general repair, we mean that repair brings the state of the system to a certain better state. A stochastic model to describe the operation in time of a repairable system which is maintained by a general repair is developed. The model contains the minimal repair case in which repair restores a system to its functioning condition just prior to failure. The sensitivity of replacement policies under a general repair to derivation from the minimal repair assumption is numerically examined. It will be seen that the policies are insensitive when the deterioration of the system is not fast and the replacement cost is high relative to the repair cost. The minimal repair assumption is then justified for such situations.
