【摘要】：針對傳統(tǒng)多階段馬爾可夫模型CMM(conventional multi-phase Markov)在建模過程中存在分析過程復雜、維數(shù)爆炸等問題,提出一種多階段馬爾可夫模型簡化算法SMM(simplified muti-phase Markov)。對該方法與CMM方法、IEC61508解析式方法中的計算負荷與精度進行數(shù)值分析。結(jié)果表明:采用SMM方法的計算結(jié)果與CMM方法的基本一致,在維持計算精度的同時避免了CMM方法中復雜的多階段馬爾可夫建模過程,極大地降低了計算量,使得安全儀表系統(tǒng)中失效概率計算更加快速且準確。
[Abstract]:In order to solve the problem of complex analysis process and dimension explosion in the modeling process of traditional multi phase Markov model CMM (conventional multi-phase Markov), a multi-stage Markov model simplification algorithm SMM (simplified muti-phase Markov) is proposed. The calculation load and precision in the method and CMM method and IEC61508 analytical method are calculated. The results show that the calculated results of the SMM method are basically the same as that of the CMM method. At the same time, the complexity of the multi stage Markov modeling process in the CMM method is avoided, and the computational complexity is greatly reduced and the calculation of the inefficiency probability in the safety instrument system is faster and more accurate.
