The Simulation and Study of the Dynamic Evolution of Group Decision-making Opinions
The time in group decision-making process is an important indicator for the decision-making performance. It has great significance to study dynamic group decision-making in the points of opinion consistency and convergence time. In this paper, we focus on the consistency of opinion evolution in group decision-making process. In order to enable the research to reflect the real situation of group decision-making process better, we modify the classic bounded confidence model by adding weight functions, which makes group decision-making a truly dynamic process. And computer simulation is the main means in our research. We first introduce the concept of weight function to dynamic group decision-making. And then several different kinds of weight function are figured out, which can be told as the convex kind, smooth kind and concave kind. These three kinds can stand for agents different willing of accepting others opinion. We make a comparison to find their different impact on the consistency of opinion evolution. The study shows that the presence of the weight function makes the dynamic group decisionmaking process more meaningful, and different weight functions make different impact on group decisionmaking process.
