可修复系统可用性模型的建立与分析

Establishment and Analysis of Availability Models for Maintainable System

从马尔可夫过程理论和系统工作的逻辑关系出发，分别导出了串、并联可修复系统可用性计算模型。在两者表达式不一致的情况下，运用数学分析的方法进行了对比，得出了两者之间差异可以忽略不计的结论，并通过典型情况下的转移概率矩阵的对比分析，找出了造成差异的根源。

The availability models for maintainable system in series/parallel connection are established by the principle of Markovian process and by the operational logic of the system respectively. The difference between the corresponding models is studied in detail by mathmatical analysis and it is found that the difference may be neglected. Through the contrast of transfer probability matrix for the typical cases ,the source resulting in the difference is also found out.
