摘要: 讨论了待命储备系统具有容错性能时的任务可靠性计算, 由于故障检测器、切换器和待命器件是否可靠,直接影响该容错系统的可靠性.为了正确评估系统的任务可靠性,这里考虑了检测器和切换器存在一定的误警率和误切换率. 据我们所知,Markov模型是处理这个问题的主要工具,而国内很少有这方面的讨论.本文用Markov理论来确定系统的状态及其状态转移矩阵, 从而容错可靠性的计算问题得到解决,此外还讨论了有关误差概率的计算模型.Abstract: The calculation of the mission reliability of a fault-tolerant standby storage system is discussed.Whether the fault detector,switch and the standby component are reliable or not affect the reliability of the fault-tolerant system directly.In order to evaluate its mission reliability correctly,the detector and switch which have a certain false detection probability and false switching probability are considered in this paper.To our knowledge,Markov model is the main tool to deal with this problem which is seldom discussed in China.Here Markov theory is applied to determine the system states and their corresponding state transfer matrix,by which the problem of calculating fault-tolerant reliability can be solved.Moreover,the calculation models of some relative error probabilities are discussed.
