Abstract: For the multi-attribute decision-making problems that alternative attribute value attribute weights are interval numbers, it uses interval numbers to improve VIKOR method and proposes a multi-attribute decision-making method based on interval number. This method uses the closest positive ideal solution as the basic idea, with linear specification strategy in the decision-making process and sort of the interval numbers by mentality indicators, and selects the best options in a stable condition of acceptable advantage and the decision-making process. The proposed method can more fully decompose different attitude index of the decision-makers, and calculate the options compromise solution in a variety of different mentality of decision-makers. Through sort analysis it can further draw the optimal solution of the multiple attribute decision-making, the results are reasonable and effective, and more consistent with the actual situation of multi-attribute decision making problems. The paper verifies the feasibility and effectiveness of the method through a representative example analysis.
