文章提出了几个保持可靠度不变的将边可靠、结点不可靠的无向网络化简以及转化成有向网络的原则，并将这些原则与已有的不交和或容斥原理方法相结合给出了一个新的计算无线通讯网络(Radio Communiction Network，简称RCN)两终端可靠度的有效算法。由于文章所给的化简与转化使RCN中指定两结点之间的路径数大大减少，因此该文算法使其可靠度的计算得到很大简化。

This paper Presents several rules to simplify an undirected network with imperfect nodes and perfect links,and to transform it into a directed network with preserved reliability. By combining these rules with the existing Disjoint-Product Method and Inclusion-Exclusion Method,a new algorithm for efficiently computing 2-terminal reliability of Radio Communication Network(RCN)has been worked out. Since the simplification and transformation greatly reduce the amount of the paths between two specified nodes,the computation for undirected RCN reliability is simplified.
