摘要
结合马尔可夫模型和可靠性框图,对三重化和双三重化两种冗余容错系统进行建模。并利用Matlab仿真分析两种系统在危险失效率、安全失效率、可用性和故障报告率的差异。
Two kinds of Redundant and Fault-tolerant Systems,Triple-channel and Double-triple-channel,are modeled by combined with Markov model and Reliability block diagram.The differences of these two kinds of systems in probability of failing dangerously,probability of failing safely,availability,and probability of failure-reportable are simulated and analysed with MATLAB.
