Abstract(in Japanese) (See Japanese page)
Abstract(in English) We discuss an approach for obtaining interval estimation of optimal software release time which is derived by a discretized software reliability growth model. The discretized software reliability growth model has a consistency with an actual collecting activity of discrete software fault-count data and is expected to conduct highly-accurate assessment of software reliability. The interval estimation must be useful for conducting software reliability assessment and flexible software management with their uncertainty because most of software reliability data are incomplete. We apply the Gibbs sampling method, which is one of the Markov chain Monte Carlo (MCMC) method, for sampling from the full conditional posterior distribution of the model parameters. The full conditional posterior distribution can be derived by following the Bayes' theory. The probability distributions of optimal software release time can be obtained through this procedures. Further, we show numerical examples of our approach by using actual fault count data.
