An integrated growth model of software reliability based on the non-homogeneous Poisson process

In this paper, we propose an integrated growth model of software reliabilitv based on the non-homogeneous Poisson process. The model shows the relationship between several distinctively developed models. It also demonstrates not only each of the major attributes of the previous models but also the combined hidden attributes of those models. In addition, we derived estimates of the parameters of the integrated growth model and subsequently, tested the model with real world data. We found that our growth model is better than previous models in its flexibility to explain the reliability of software attributes and ability to apply to various situations in the real world.
