Abstract: In this paper,the SCEM-UA algorithm is used to estimate the parameters of mixed Weibull distribution in automotive reliability analysis,and the results using SCEM-UA algorithm are compared with the results using Maximum Likelihood Estimation(MLE).The comparison shows that the SCEM-UA can obtain more accurate results than MLE.

Key words: SCEM-UA, mixed Weibull distribution, reliability analysis, parameter estimation
