Abstract A software hazard rate model is known as one of the important and useful mathematical models for describing the software failure-occurence phenomenon and conducting quantitative software reliability assessment. In this study, we develop a more realistic software hazard rate model by considering with the effect of multiple change-point occurrences for more plausible software reliability growth modeling and improving the accuracy of software reliability assessment based on a sowtware reliability growth model. Finally, we conduct goodness-of-fit comparisons of our model with existing models, and show numerical examples of software reliability assessment based on our model by using actual data.
