Abstract

Purpose – The purpose of this research is to incorporate the exponentiated Weibull testing-effort functions into software reliability modeling and to estimate the optimal software release time. Design/methodology/approach – This paper suggests a software reliability growth model based on the non-homogeneous Poisson process (NHPP) which incorporates the exponentiated Weibull (EW) testing-efforts. Findings – Experimental results on actual data from three software projects are compared with other existing models which reveal that the proposed software reliability growth model with EW testing-effort is wider and effective SRGM. Research limitations/implications – This paper presents a SRGM using a constant error detection rate per unit testing-effort. Practical implications – Software reliability growth model is one of the fundamental techniques to assess software reliability quantitatively. The results obtained in this paper will be useful during the software testing process. Originality/value – The present scheme has a flexible structure and may cover many of the earlier results on software reliability growth modeling. In general, this paper also provides a framework in which many software reliability growth models can be described.
