Bayes method for torpedo reliability assessment

Bayes method is widely applied to the reliability assessment of the subsample product, but the foretaste distribution will directly affect the result of the reliability assessment. When the Bayes method is utilized to assess the torpedo reliability, the foretaste distribution of the success-failure system is regarded as β(0,0), this is not scientific. The paper explains the foretaste distribution should be β(0,0) from the theory and the engineering reality, and presents the Bayes correction formula that can convert the test data of the parts into the test data of the system.
