First, we research and discover the problems of employee's performance evaluation: the contents and standard of results evaluation, principal and period, the appliance of evaluation performance. The standard of performance evaluation isn't unification, overmany evaluation principal and overmuch evaluation period make more difficulties in the process of the evaluation, and the appliance of evaluation result isn't perfect. Then we analysis these problems and give our suggestion,confirm the Key Performance Indicators as the foundation of the evaluation.

The thinking of this method as follows:Firstly,using single evaluation methods to evaluate.If the evaluation results aren\'t same,the Spearman rank correlation coefficient is used to calculate the correlation among the results of single evaluation methods.Based on the results,the traditional combined evaluation methods are used to combine the results of the single evaluation method.If the results of the upper combined methods are not same. Here the combined method evaluation indexes,such as Spearman rank correlation coefficient,correlation degree,the max deviation,average deviation,are used to evaluate the upper four combined evaluation methods.The entropy method is used to calculate the weights,and then get the final evaluation result.
