Abstract: In this paper,the mean square method and the AHP are used to calculate the index weights.Using gray correlation analysis,20 key projects are evaluated.The result of scatter degree method is used as a reference.Through horizontal and vertical comparison,the difference and characteristic of subjective and objective method are concluded.The result shows that the correlation coefficients of the three methods are between 0.7and 0.9.The evaluation results are in line with each other.Thus it provides a scientific method and basis for calculation of index weights.
