摘　　要：为了简化系统可靠性和可用性的建模和分析过程 ,提出了一种简化 Markov模型的方法 .通过对系统进行简化 ,忽略掉一些不重要的过程 ,减少相应 Markov模型中的状态数来简化计算 .通过对系统建立的简化模型进行误差分析 ,在已知被忽略状态的最少信息的前提下得到简化模型的误差界限 .By simplifying the system, neglecting unimportant processes and reducing the states in corresponding Markov model a method was presented to simplify the modeling and analyzing of the system reliability and availability. And the error is analyzed for the simplified Markov model and the error bound is presented with the minimum information of the neglected states. The results precision got from the simplified model can be judged in terms of the error bound.
