Abstract
A cost model subject to times to remove errors in the software system and risk cost due to software failure is developed. A software reliabi lity model based on the non-homogeneous Poisson process is used. The o ptimal release policies to minimize the expected total software cost a re discussed. A software is also developed using Excel and Visual Basi c tools to facilitate the task of determining the optimal software rel ease time. Numerical examples are provided to illustrate the results.
