计算网络两端可靠性的不交化改进算法

AN IMPROVED DISJOINTING ALGORITHM FOR CALCULATING THE RELIABILITY OF S-T NETWORKS

针对现实网络图的非封闭性特点,对可靠性不交化算法进行了改进,其主要思想就是根据网络图的最小路集把网络图分解成数个子图,求出这些子图的最小路集并对它们进行不交化运算求出所有子图的可靠性,进而求出整个网络图的可靠性。最后对改进前后的算法效率做了比较。

According to the topology of real networks not always being close in,an improved disjointing algorithm for calculating the reliability of networks is put forward. Its basic idea is that judging by the minimal paths the networks graphic is divided into sub-graphics ,after sub-graphics is disjointed by each minimal paths,we can get each sub-graphics reliability ,and the reliability of the networks graphics can be calculated by these sub-graphics reliabilities. The efficiencies of the two different algorithms are compared in the end of the article.
