摘　　要：考虑了两部件串联且只有一个修理工的可修系统.在假定部件的寿命和修理时间分布均为负指数分布,但部件每次失效后都不能修复如新的情况下,利用几何过程和补充变量法,并使用一种构造矩阵的新方法,求出了系统的一些主要可靠性指标.This paper considers a two-units series system with a single repairman. In the system, the life distribution and the repair distribution of the units are assumed to be exponential distributions, but it is still assumed that the units after repair are not“as good as new”. By using the geometric process, the method of supplementary variable and a new method of matrix, some important reliability indices are determined.
