Abstract We propose a discrete Weibull-type software reliability growth model in order to improve the reliability evaluation accuracy based on Software Reliability Growth Model by applying a discrete reduced modified Weibull distribution, which has better fitting performance than the conventional discrete Weibull distribution to the software failure-occurrence distribution. Finally, we conduct goodness-of-fit comparisons of our model with existing model, and show the numerical examples of software reliability assessment based on our model by using actual data.
