A fast algorithm for the performance index of a telecommunication network

A performance index for a telecommunication network is defined as a composite index integrating the important measures of both reliability and capacity. In this index the network states that permit a flow capability less than the maximum, are not totally ignored but are assigned a normalized weight less than one. A fast method is proposed for deriving the symbolic expression of the performance index in a compact form. Because the capacity of several subnetworks must be computed, an efficient procedure for capacity determination is also suggested. An example illustrates the procedure and points out the simplicity of the resulting expression for the performance index
