Study on the Method of Determining Objective Weight of Decision-Maker (OWDM) in Multiple Attribute Group Decision-Making

In multi-attribute group decision-making, the aggregating result is much depended upon objective weight of decision makers. For getting a more accurate aggregating result quickly, a method of determining OWDM to attributes in interactive decision-making is presented in this paper, which is based on thinning the objective weight of decision makers down the objective weight of decision makers to attributes. Then a definition of consensus degree and the flow of interactive decision-making based on the objective weight of decision makers to attributes are proposed.
