Abstract
Almost all the existing software reliability models are developed in the context of probability, and thus called probabilistic software reliability models (PSRMs). Unfortunately PSRMs have serious shortcomings such that we have to face the unpleasant fact that more and more PSRMs are proposed and none of them is shown to be tractable and universal. In this paper we show that the probability assumption for PSRMs is not reasonable as a result of the uniqueness of software. Fuzzy software reliability models (FSRMs) should be developed in place of PSRMs because the software reliability behavior is fuzzy in nature. Finally we demonstrate how to develop a simple fuzzy model to characterize software reliability behavior. © 1991.
