One of the important applications of software reliability models is the determination of software release time. Most of the existing studies on this topic use models based on nonhomogeneous Poisson process with a bounded mean value function. In this paper, nonhomogeneous Poisson process models with unbounded mean value function is used for the determination of the optimum software release time. Both reliability criteria and cost minimisation are discussed together with the used of combined criteria. Furthermore, we also consider the case of interval estimation for the software release time as point estimation is usually inaccurate.
