On a unified theory of some nonhomogeneous Poisson process models for software reliability

Abstract

In this paper, we show how several existing software r eliability growth models based on nonhomogeneous Poisson processes NHPPs can be c omprehensively derived by applying the concept of the weighted arithmetic, weighted g e ometric, or weighted harmonic mean. Furthermore, based on these three weighted means, we thus proposed a more general NHPP model from the viewpoint of quasi arithmetic mean. Under this general framework, we can not only derive some existing NHPP models but also can derive some new NHPP models.
