Indexes of a telecommunication network

Two recently proposed performance indexes for telecommunication networks are shown to be the s-t and overall versions of the same measure, namely, the mean normalized network capacity. The network capacity is a pseudo-switching-function of the branch successes, and hence it means value is readily obtainable from its sum-of-products expression. Three manual techniques of conventional reliability analysis are adapted for the computation of the proposed performance indexes: a map procedure, reduction rules, and a generalized cutset procedure. Four tutorial examples illustrate these techniques and demonstrate their computational advantages over the state-enumeration technique
