A summary of discretized software reliability growth models

A software reliability growth model is one of the fundamental technique to assess software reliability quantitatively. The software reliability growth model is required to have a good performance in terms of goodness-of-fit, predictability, and so forth. In this paper, we summarize discretized software reliability growth modeling and its applications. As to the software reliability growth modeling, discretized nonhomogeneous Poisson process (NHPP) models axe investigated particularly for accurate software reliability assessment. The discrete NHPP models have better performance than discretized deterministic software reliability growth models which have been proposed. Further, as one of the interesting issues for an application technology of a software reliability growth model, optimal software release problems under simultaneous cost and reliability requirements are discussed in this paper.
