Bayesian assessment of system reliability with zero-failure data in different environments
The electronic display and control system of ship equipment undergoes many kinds of tests in the development stage,and there are obvious differences in the stress of the test environment and zero failure in the test process.Based on the failure rate of the electronic display and control system,the method of determining the confidence interval of the environmental factor under the zero-failure condition is proposed,and the way of converting the test time and failure data of each stage under the zero-failure condition is also proposed.The priori distribution model of the failure rate of the electronic display and control system is constructed,and the Bayes method is used to integrate the test information to give the point estimate and confidence limit of the failure rate to facilitate the subsequent reliability assessment.The validity of the reliability assessment method is verified by taking the electronic display and control system of a ship as an example.A reference for the reliability assessment of the electronic display and control system of typical ship equipment is provided.
