由于在实际生产中，大多数机组的工作时间是有限的，因此如何在有限的时间跨度内实际考虑一些维护策略将是一个重要的问题。本文将常用的维修模型转化为有限维修模型。研究有限时间跨度的理论最优策略比研究无限时间跨度的理论最优策略要困难得多。将常用的最小维修周期更换模型、分段更换模型和简单更换模型转化为有限更换模型。进一步，考虑了不完全预防性维护和有限时间范围内检查模型的最优周期和顺序策略。对每个模型的最优策略进行了解析推导和数值计算。
It would be an important problem to consider practically some maintenance policies for a finite time span, because the working times of most units are finite in actual fields. This paper converts the usual maintenance models to finite maintenance models. It is more difficult to study theoretically optimal policies for a finite time span than those for an infinite time span. Three usual models of periodic replacement with minimal repair, block replacement and simple replacement are transformed to finite replacement models. Further, optimal periodic and sequential policies for an imperfect preventive maintenance and an inspection model for a finite time span are considered. Optimal policies for each model are analytically derived and are numerically computed.
