A Simulator for Reliability Predictions of Fault-Tolerant System Architectures.

Abstract

This study is concerned with a simulation technique suitable for predicting the reliability of fault-tolerant system architectures. General fault-occurrence probability density functions are introduced, and techniques for generating postulated fault environments using these functions are presented. Methods for assigning faults to subsystems of a system exposed to a given fault environment are discussed and the utility of these methods for making reliability predictions is illustrated with a specific example derived from the radar field. The simulator which has been written in FORTRAN-77 is highly interactive and user oriented, and provides in addition to system reliability estimates, system MTBF and availability estimates under various repair strategies and degrees of fault coverage.
