Cost–reliability optimum release policies for a software system under penalty cost

Abstract

Optimum software release policies are considered, minimizing the expected software cost simultaneously with the reliability requirement. Cost here also includes the penalty cost which is incurred by the manufacturer for not delivering the software at scheduled delivery time. The underlying software reliability growth models (SRGMs) are based on the non-homogeneous Poisson process (NHPP). Numerical results are also presented.
