摘要： 研究动态群体决策中子群体之间的交互对群体决策观点收敛时间及其稳定性的影响。设定合理的决策观点交互规则，即考虑子群体内部个体之间决策观点交互和不同子群体之间的决策观点交互，建立动态群体决策观点演化模型。仿真实验结果表明，子群体之间交互会促进整个群体达成共识；子群体的信任水平越高，群体决策观点的收敛时间越短，且收敛时间的稳定性越好；子群体间交互观点数目增多会缩短群体决策观点收敛时间。

Abstract:  According to sociological theory, in group decision making, subgroups and interaction among the subgroups widely exist. Members from different subgroups always exchange opinion and learn from each other, influencing the opinion evolution. This paper studies the impacts of interaction among subgroups on the opinion convergence and its stability in the dynamic group decisionmaking. The rules of opinion interaction among individuals within the same subgroup and between different subgroups are setup. Then, a model is presented to describe the dynamic opinion evolution in considering the interactions. With the model, simulation analysis is carried out. Results indicate that the interaction among subgroups promotes achievement of opinion consensus. The higher the mutual confidence level among the subgroups is, the faster the opinion converges, and the higher the stability is. Also, the larger the number of the pieces of opinions flows among the subgroups, the faster the decision making process converges.
