【Abstract】 In view of the issue of choosing the failure distribution model in the reliability estimationof nonelectric products. the feasibility and dependability study on substituting the expenentialdistribution for the Weibull’s under the condition of small sample is conducted. The criteriaand figures of evaluation are established, and the statistical result is obtained through MonteCarlo simulation. An example of engineering application is given as well.更多还原
