Abstract
This paper is an attempt to relax and improve the assumptions regarding software reliability modeling. To approximate reality much more closely, we take into account the concepts of testing compression factor and the quantified ratio of faults to failures in the modeling. Numerical examples based on real failure data show that the proposed framework has a fairly good prediction capability. Further, we also address the optimal software release time problem and conduct a detailed sensitivity analysis through the proposed model. © 2010 IEEE.
