Book describes selection of software reliability models. Numerous models have been developed, but which one should be used, is still a challenging area for software managers. Software development life cycle based classification of models and particle swarm optimization employed for parameter estimation has made selection an easy task. The main goal of this book is to develop deterministic & quantitative models for software reliability model selection. A set of model selection criteria have been employed in an integrated manner for evaluation, comparison and optimal selection of software reliability models. Students will find the book both stimulation and accessible, while researchers will be guided smoothly through the material required for good grasp of the theory and application of these models. Pointers to relevant literature ensure that it forms an ideal starting point for further study.
