Risk Analysis of Reliability Assurance Test in the Case of Exponential Distribution

Zhihua Zhang

Open publisher page 1 citations

Abstract

As the test time needed is very short,the assurance test is highly appreciated. The hierarchical prior distribution of failure rate was determined based on reliability acceptance test data.The risks of special assurance test(0.212 test) from Bayesian statistical viewpoint were analyzed,a sampling scheme for the assurance test in exponential case was given.An example illustrates that the method is feasible.
