A Bayes Method for Reliability Calculation of Gas Fire-Extinguishing System

The reliability of gas fire-extinguishing system is difficult to calculate because of the small sample size, so this paper uses Bayesian method to calculate reliability of the gaseous fire-extinguishing system. The method process includes conversion of multi-source prior information, information fusion, information check, weight calculation and reliability calculation of unit and system. The method properly solves the problem of reliability calculation by combining the field sample information with multi-source prior information.
