摘要
容错系统的可靠性分析是容错系统设计过程中最重要的步骤之一。在容错控制系统的可靠性分析中 ,利用马尔可夫过程和半马尔可夫过程理论对容错系统进行可靠性建模能够较为真实地描述系统的实际工作情况。但是 ,由于容错系统为了达到高可靠性而采用了大量的冗余配置及重构技术 ,使得该可靠性模型往往变得相当复杂。因此 ,对系统可靠性模型进行必要的化简 。
Reliability analysis is very important in designing a fault tolerant system. In the reliability analyzing of such a system, Markov process and semi Markov process theory can be applied to describing the original working condition of the system. But any analytic model of such a system has a large number of states, making the solution computationally intractable. This leads to the need for simplified techniques.
