Continuous Bayesian Reliability Demonstration Test Method for Safety Critical Software
The classic software reliability demonstration test (SRDT) takes no consideration of prior knowledge and priori distribution adequately, which causes overly cost of work and resource. A new improved Bayesian based SRDT method has been proposed. First a framework for continuous Bayesian SRDT scheme has been constructed. Based on the framework the decreasing function has been employed to construct the priori distribution density functions for continuous safety-critical software, and then continuous Bayesian software demonstration function (CBSDF) scheme has been presented. A set of comparative experiments have been carried out on several published data sets. The experimental results reveal that CBSDF scheme is more efficient and applicable especially for the safety-critical software with high reliability requirements.
