摘要
故障树模型和Markov模型是可靠性分析中最常用的两种方法。探讨了从故障树模型到Markov模型的转换问题。通过通常的列举法从树得到的Markov模型的状态数在基本器件数目很多时将会非常大。为简化模型,提出了用合并法和层次法来减少Markov模型的状态数。利用这两种方法不但可以减少状态数,而且简化了Markov模型的计算。
Fault-tree model and Markov model are two commonly used analytical methods for system rdliability .The conversion from fault-tree model to Markov model is discussed.In order to simplify the Markov model,merging method and hierarchy method are presented.Compared with the enumerating method,these two methods not only reduce the numbers of the states,but also simplify the computotion of the Markov model.
