NHPP-Based Software Reliability Growth Modeling and Optimal Release Policy for N-Version Programming System with Increasing Fault Detection Rate under Imperfect Debugging

Abstract

Attempts have been made to propose a software reliability growth model (SRGM) based on non-homogeneous Poisson process for NVP system. The proposed model concerns the combined effect of increasing fault detection rate and fault removal efficiency under imperfect debugging. Moreover, a cost model has been developed. Also, an optimal release policy based on the proposed cost model and the number of remaining faults has been discussed. The performance of the proposed model has been compared with existing SRGMs for NVP system. Toward the end, the proposed model has been validated using some real data.
