A UNIFIED APPROACH FOR DEVELOPING SOFTWARE RELIABILITY GROWTH MODEL USING INFINITE SERVER QUEUING MODEL

In the past 35 years numerous software reliability growth models (SRGMs) have been proposed under diverse testing and debugging (TD here we propose a unification modeling approach applying the infinite server queuing theory based on the basic assumptions of an SRGM defining three level of complexity of faults. Our unification methodology can be used to obtain several existing and new SRGMs which consider testing a one stage process with no fault categorization, two/three stage process with random delay functions and hence categorize faults in two/three level complexity. We have also provided data analysis based on two actual T&D data set for some of the models discussed and proposed in the paper.
