Abstract: | An important question in the developing process of software products is when to stop testing to make the gain in reliability
justify the costs. In this paper, a software reliability-cost model is presented to determine the optimal release policies
that maximize the expected net gain in reliability. Several software cost factors are considered in this study, such as the
cost of removing detected errors and the risk cost due to software failure. The error removal cost is modeled based on a stochastic
process. A software reliability model based on the non-homogeneous Poisson process is used. Numerical examples are provided
to illustrate the results.
