A new approach for grey multi-attribute decision making

The decision-making method for the grey multiple attribute decision-making problems is presented. Firstly, a new kind of similar degree between two interval grey numbers is established by combining the Euclidean distance with grey correlation degree to appraise the scheme. Then, the average similar degree is constructed, which reflects the distance and the difference of data curves among a selected scheme, the ideal solution and negative ideal solution. Thus, this method has clear physical implication. Finally, an example is given to show the feasibility and effectiveness of the proposed method.
