【摘要】 本文应用网格图的分析方法，将双环同的可靠性问题，归结为相应的网格图的顺向链路或逆向链路的可靠度计算，应用布尔代数的概率方法，分别求出具有不同跳距Ｓ的双环网的可靠度、平均无故障时间和平稳利用率。最后，在总结点数Ｎ＝９时，对３种不同的双环网可靠性参数进行分析与比较，并给出最优菊花链双环网的模型。更多还原

【Abstract】 In this paper, on the basis of the analysis method of the net list graph, we present a method for calculating the forward or backward link reliability of the net list graph to solve the reliability problem of dual ring net, and solve respectively reliability, mean time between failure (MTBF) and availability of dual ring netwith the different skip distance (8) in the light ofBoolean algebra. At last, when the total node numbers are 9, we analyse and compare the reliability parameter among three kinds of dual ring net, and give forth the optimal model of dual ring net with the daisy lin k.更多还原
