determining the weight of decision makers in group multiple attribute decision making

In this paper, we present a method to determine the weight of decision makers(dms) in group multiple attribute decision making (gmadm) problems. our method is based on the concept that the best alternative is closer to the positive ideal solution and far away from the negative ideal solution, simultaneously. the proposed method not only determines the weight of dms, but also ranks the alternatives. the method is illustrated through an example.
