| Abstract: | In this paper,a method based on Bayes theory is presented aiming at the problems of small sample maintainability verification for the key parts of armored equipment.And Posterior Probability Ratio Test of maintainability index verification in the logarithmic normal distribution is discussed in detail.By analyzing the test data of armored equipment′s key components,it is proved that the method is effective and reasonable to reduce the sample size and test cost. |
