The approximate analysis of reliability of large-scale parallel communication networks with various subsystem configuration

This paper presents the new effective method of evaluating the reliability of large parallel repairable systems. The system consists of elements with different characteristics of reliability. It is assumed that the recovery time of elements is generally distributed. The represented result was obtained by analytical method with the using of semi-Markov model of reliability. The application of analytical result obtained here for reliability estimation is more effective than Monte-Carlo simulation.
