Hierarchical Bayesian method on the basis of maximum posterior risk |
| |
Abstract: | In order to carry out the reliability qualification test of production in exponential case, the hierarchical prior distribution is given at first, and then a plan of reliability qualification test is formulated by using Bayesian method on the basis of maximum posterior risk. The time of test is shortened, and the cost is cut down according to the plan of reliability qualification test. |

Keywords: | exponential distribution hierarchical prior Bayesian method maximum posterior risk |
