Important Milestones in Software Reliability Modeling

A number of software reliability models have been proposed for assessing the reliability of a software system. In this paper, we discuss the time-domain and data-domain approaches to software reliability model-ing, and classify the previously reported models into these two classes based on their underlying assumptions. The data-domain models are further classiied into fault-seeding and input domain models, while the time-domain models are further classiied into homogeneous Markov, non-homogeneous Markov and semi-Markov models. We present some representative models belonging to each of the classes, and then discuss the relative merits and limitations of the time and data-domain approaches.
