Several classes of nonparametric priors are employed to model the rate of occurrence of failures of the nonhomogeneous Poisson process used in software reliability or in repairable systems. The classes include the gamma process prior, the beta process prior, and the extended gamma process prior. We derive the posterior distribution for each process. Sampling based methods are developed for Baye...

Due to the randomness and time dependence of factors affecting software reliability, most reliability models are treated as stochastic processes, non-homogeneous Poisson process (NHPP) is used one. However, failure behavior does not follow NHPP in a statistically rigorous manner, pure random method might be enough describe behavior. To solve these problems, this paper proposes new integrated ap...
