Abstract: In this paper,we analyzed the disadvantage of traditional TOPSIS, and presented a new decision-making method based on grey correlation degree and TOPSIS.This method established a new kind of relative similarity degree by combining the Euclidean distance with grey correlation degree.The new similarity degree reflects the distance and the different shape among a selected scheme, the ideal solution and negative ideal solution.Its implication is clearer.At the end,this method is explained by an example.

Key words: TOPSIS, Euclidean distance, gray correlation degree, relative similarity degree
