Consistency Formation of Fuzzy Multi-Attribute Group Decision Making Based on Alternative Adjustment

Abstract

Analytic hierarchy process (AHP) is a method usually used in group decision making. The process of group decision making using AHP is essentially an individual preference of the decision maker incorporating process. In this process, it becomes one of the cores for studying theory and method of group decision making, how we incorporate effectively different forms of preference information. Therefore, in this paper, we propose a solution which makes consistency preference of decision maker group form finally by decision alternative adjustment. We can make clear the deference of decision preference of each division on basis of group division by means of decision information of the decision maker and put forward to employ flexibly AHP for consistency formation of fuzzy multi-attribute group decision making. Thus, an effective dynamic group decision making process is formed. A group decision making example of market approves of new tissue product shows the feasibility of the proposed method.
