几何过程与冷贮备系统分析

Geometric Process and Analysis of a Cold Standby System

本文介绍了几何过程的定义及有关结论，研究了两个同型部件、一个修理工组成的冷贮备可修系统，当部件的使用寿命和维修时间均为指数分布时，在故障后的部件不能“修复如新”的前提下，利用几何过程与补充变量法求得了一些主要可靠性指标。

In this paper,the concept of geometric process is introduced and a two-identical componentcold standby repairable system with one repairman is studied. In the system,the life distributionsand the repair distritutions of the two components are assumed to be exponential distributions,butit is still assumed that the component after repair is not 'as good as new'. Under above assumptions,by using geometric process and the method of supplementary variable,some reliability indicesare derived.
