| Abstract: | By construction two statistic quantities and applying the central limit theorem,this paper put forward a new approach to the estimation of confidence limits on parameters and reliable life and reliability for the two-parameter weibull distribution.Comparing with the existing approaches,this approach simplifies largely the estimating procedure and has more better accruacy.An example of the application of this approach to the estimation of confidence limits on reliable life and reliability of mechanical products is shown in the paper. |
