For the problem of multi-attribute decision making, in which the attribute values and the weight of each attribute are interval numbers,interval valued fuzzy VIKOR method is discussed.VIKOR method uses linear normalization matrix during the process of decision making.Interval numbers ranking is determined by the index of decision-maker's attitude,the compromise solusion is obtained under the conditon of acceptable advantage and acceptable stability in decision making.Finally,an illustrative example is given when the weight of maximum group utility equals 0.5.The result shows that the selection changes with the index of decision-maker's attitude.
