摘要

在可修复系统中，可用性作为一种可靠性测度，其指标可用度是基本的；然而从实际应用角度来说平均无故障工作时间和平均修复时间有时显得更为重要，却又往往难以得知．本文首次提供了计算一般系统的MTBF和MTYR的有效公式，此系统具有负指数分布失效和修复时间部件．

Abstract

The availability of a repairable system represents a basic and elementary measure within reliability engineering. But the mean time between failures （MTBF）and the mean time to repair （MTTR）

which are commonly difficult to know

are by themselves quantities of practical interest

and can be even more important than system availability. This paper presents a method to determine the MTBF and MTFR of a repairable system with unlimited repair and exponential inter-failure and repair time at component level.
