A cost model subject to times to remove errors in the software system and risk cost due to software failure is developed. A software reliability model based on the non-homogeneous Poisson process is used. The optimal release policies to minimize the expected total software cost are discussed. A software is also developed using Excel and Visual Basic tools to facilitate the task of determining the optimal software release time. Numerical examples are provided to illustrate the results.
