基于Markov model的容错计算机联锁系统可靠性分析

The reliability analysis of fault tolerant computer interlocking system based on Markov model

容错设计是提高计算机系统可靠性的有效手段。本文研究了容错控制系统可靠性概念的内涵和定义,并结合工程实践讨论了我国的一种典型容错计算机联锁系统,且建立了考虑故障恢复和故障处理能力的多阶马尔可夫模型,进行了定量分析。

Fault-tolerant design is an effective method to improve the reliability of computer systems. The intension of concept of reliability and the definition of reliability are researched with the experience in project practice, a typical fault-tolerant computer-based interlocking system is discussed by seting up the Markov model which takes the transient fault and fault states into account, the quantitative analysis are also presented.
