| Abstract: | In this paper, Weibull distribution and mixed Weibull distribution are adopted in describing the reliability of gear. Distribution parameters are estimated by using the maximum liklihood method. The liklihood funCtions are maximed by optimizing. Results show that, for data adopted here, mixed Weibull distribution is more suitable than Weibull distribution. |
