Software reliability growth models (SRGMs) investigating software debugging process have recently been developed by some researchers to estimate software reliability measures. However, these SRGMs either did not involve resource expenditures spent on fault remove process or assumed that the rate of resources consumed is constant. In practice, software fault intensity may be not continuous for many conditions. Thus, in order to address the problem, this paper develops models incorporating the resource expenditures and change-point, which spent on software debugging process. A real software failure project is demonstrated the effectiveness of proposed models, and numerical results prove new models can provide better fit and prediction.
