| Abstract: | In view of determination of parts repair period and reliability life met in practice, the method of maximum likelihood estimation for the three-parameter Weibull distribution based on wear out fault is put forward. Its validity and effectiveness has been verified by simulated calculation in this paper. Its application in practice is explained through a practical example. |
