| Abstract: | Based on theory of ordering method in the sample space,we discuss the lower confidence limits for the reliability in the case of Weibull distribution under the time censoring and the type Ⅰ censoring,the shape parameters is in some finite interval.Our main result is the following： for prearranged confidence level and a sample with arbitrary size,we give the exact lower confidence limit for the reliability and its effective conputing methods. |
