Abstract
Optimal software testing-effort allocation policies based on an optimal release problem with delivery-delay minimizing the total expected software cost are discussed. Such cost considerations enable us to make a release-decision as to when to transfer a software system from testing phase to operational phase. The underlying reliability model describing a software fault occurence phenomenon is a software reliability growth model based on a nonhomogeneous Poisson process. It is assumed that the penalty cost function due to delay for a scheduled software delivery time is proportional. Numerical example is shown to illustrate the results.
