In this paper, the authors will first show how several existing SRGMs based on NHPP (Non-Homogeneous Poisson Process) models can be comprehensively derived by applying the time dependent delay function. Moreover, for most conventional SRGMs, they assume that detected errors are immediately corrected. But this assumption may not be realistic in practice. Therefore, they will incorporate the ideas of failure dependency and time-dependent delay function into software reliability growth modeling. New SRGMs are proposed and numerical illustrations based on real data set are presented. Evaluation results show that the proposed framework to incorporate both failure dependency and time-dependent delay function for SRGM has a fairly accurate prediction capability.
