Research On Interactive Group Decision-making Based On Two Kinds Of Information Aggregation Method

Group decision-making is an effective means to handle a variety of major problems such as policy decisions and allocation problems in real society. To solve some large and complicated decision problems, group decision-making can produce much more alternatives to get more reliable results and to achieve higher performance of group decision-making..Due to the diversity of members in the decision knowledge structure, however experience and demand and the openness of the system, the decision-making process will inevitably produce conflict. Therefore, the processes to solve the conflict effectively need to communicate between members, to gradually modify their decision making judgment through many opinions interaction, learning and feedback and to realize group consensus.In this paper, the two kinds of information aggregation mode of interactive group decision method are studied. The paper first reviews the research status of interactive group decision and introduces the framework of the paper and writing ideas. The second chapter is an overview of two types of information aggregation method, and describs characteristics and Scope of the two types of information aggregation model. The third chapter studies the decision matrix and the attribute weights aggregation method and group information aggregation method. According to the difference between the same decision makers in establishing decision matrix and determine the attribute weights ability to determine the weight of decision makers and adopt the TOPSIS method for the final order. The fourth chapter studies the group information gathering conditions respectively individual opinions and views of the consistency of the group, and puts forward the interactive group decision making method. The fifth chapter studies the concept of satisfaction. On the basis of a comprehensive review of the concept of alternative achievement scale, the paper studied the characteristics of satisfaction and puts forward the satisfaction function expression. According to the characteristics of the satisfaction function, the sixth chapter puts forward the interactive group decision method in order to achieve group satisfaction. The seventh chapter is the summary and outlook, which summarizes the paper’s conclusion and prospects the future area.The main contribution of the paper is depicted as followings:1. Based on the individual decision makers weight and judgment matrix information aggregation respectively conditions, the paper puts forward the group consistency measure model, and puts forward the interactive adjustment method and the specific steps. 2. The paper portrays deeply the concept of decision makers’ satisfaction, constructs the individual decision makers’most satisfied and most unsatisfied empowerment model, and defines the function expression of satisfaction and to measure the approval degree to decision result of decision makers with satisfaction index.3. According to the lottery mechanism, market mechanism design rules, on the basis of satisfaction index and the planning theory thought, the paper establishes the interactive group decision-making model, designs the algorithm, and gives the specific interactive steps.
