Abstract

Assurance of software reliability is an important factor in software applications, and the process of software testing has become one of the essential requirements in software development. Many software reliability growth models have been developed based on non-homogeneous Poisson process, which incorporates logistic testing effort function. The paper proposed and developed a delayed S-shaped software reliability growth model with imperfect debugging, which integrates the Burr Type XII testing effort function. The testing effort function parameters are estimated by least square estimation method and S-shaped software reliability growth model parameters by maximum likelihood estimation. Various software reliability growth models are investigated through three data sets under perfect debugging and one data set under imperfect debugging. It is found that the proposed delayed S-shaped software reliability growth model with imperfect debugging has a better error prediction capability.
