| 摘 要： | 本文研究了单部件,一个修理工组成的可修系统,在故障系统（部件）不能“修复如新”的前提下,我们以系统的故障次数和工作寿命组成的二元函数（Ｎ,Ｔ）为其策略,选择最优的策略（Ｎ,Ｔ）使得系统经长期运行单位时间内的期望费用达到最小,而且求出了系统经长期运行单位时间内的期望费用的明显表达式．

| Abstract: | This paper considers a repairable system consisting of one unit and a singlerepairman. Assume that the system after repair is not"as good as new".Under this assumption,the twovariable optimal replaccmemt policy(N,T )which makes the long-run average cost per unit timeminimal based on the number of failures and the working age is discussed.Meanwhile,the expression ofthe long-run average cost per unit time minimal is derived. |
