Abstract：For the products with parameters digression feature,the reliability distribution is studied.The character and parameter estimation methods of the common distributions are analyzed,such as index distribution,normal distribution,log-arithmic normal distribution,three-parameter Weibull distribution,and Gamma distribution.For the scope of the product re-liability which obtained from the practice is different,the fitting analysis of reliability curve is studied for three kinds of situa-tion.The simulation results demonstrate if the scope of parameters can be obtained before parameter estimation the normal distribution and logarithmic normal distribution are fitting better,otherwise the three-parameter Weibull distribution is fit-ting better.
