Abstract
It is important to make a software system more reliable. We discuss reliability assessment for redundant software systems developed by multiversion programming, i.e., N-version programming and recovery blocks systems, during the operation phase. In this paper, the reliability assessment measures such as software reliability function, hazard rate function, and MTTF (mean time to failure) are obtained by using two software reliability growth models, i.e., Jelinski-Moranda and NHPP models. Also the results of reliability assessment based on the two software reliability growth models are numerically compared for each redundant software system.KeywordsAcceptance TestSoftware ReliabilitySoftware FaultOperation PhaseHazard Rate FunctionThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
