SYMRAP: A symbolic reliability analysis program

This report describes the major contribution of a research effort to identify methods to be used regarding the collection and processing of data which are required for system control of a switched digital integrated communication network. At the early stages of the effort it was discovered that decisions on data collection could not be made until a good network analysis algorithm was devised. One of the major items needed in the analysis was a fast algorithm for computing terminal-pair reliability for a probabilistic graph. This report describes the algorithm developed as well as presenting a documented computer codes with users manual and examples. The body of the report is written for one who has some familiarity with communications network theory and probabilistic graphs.
