为了有效地利用一个运行中的系统，本文提出，当更换时间可以安排在一个计划的时间T的操作，并在N个最小的维修，新提出的方法，无论发生在最后，应采用到优化的政策考虑。采用经典的先发生者替代策略与后发生者替代策略进行比较。此外，使用超时技术，在本文中的时间T的更换计划修改为在第一次故障后，T已经到达，以避免可能的中断运行作业。也就是说，系统在时间T之前的故障N处被替换，或者在T到达之后的第一个故障处被替换，无论哪个先发生，或者最后发生。详细分析了首修法和末修法下的策略，并给出了它们的期望费用率。获得了单独和双变量T和N的最优解，并进行了分析比较。
To make effective use of a running system, this paper proposes that, when replacement times could be scheduled at a planned time T of operation, and at a number N of minimal repairs, the newly proposed approach of whichever occurs last should be employed into optimizations for policy consideration. The replacement policy with the classical approach of whichever occurs first is also used to make comparison with the approach of whichever occurs last. Further, using the overtime technique, a replacement scheduled at time T in this paper is modified to be done at the first failure after T has arrived, to avoid probable interruptions for running jobs. That is, the system is replaced at failure N before time T, or at the first failure after T has arrived, whichever occurs first, and last, respectively. The policies acting on the approaches of first and last with minimal repairs are analyzed in detail, and their expected cost rates are formulated. Optimal solutions for separate and bivariate T and N are obtained and compared analytically.
