Reliability Modeling of Compensating Module Failures in Majority Voted Redundancy

Abstract

The classical reliability model for N-modular redundancy (NMR) assumes the network to be failed when a majority of modules which drive the same voter fail. It has long been known that this model is pessimistic since there are instances, termed compensating module failures, where a majority of the modules fail but the network is nonfailed. A different module reliability model based on lead reliability is proposed which has the classical NMR reliability model as a special case. Recent results from the area of test generation are employed to simplify the module reliability calculation under the lead reliability model.
