Abstract In this paper, we investigate the group decision making problem in which the attribute values are given as interval numbers, and the attribute weights are able to be determined appropriately. The contribution of this paper is to determine the weights of Decision Makers (DMs), using an extended projection technique. We define the ideal decision of all individual decisions as their average. The weights of DMs are determined according to the extended projection of each individual decision on the ideal decision. Finally, we give an example to illustrate the developed approach.
