摘　　要：通过建立动态群体决策观点演化模型,研究个体知识学习对动态群体决策观点稳定性和收敛时间的影响。分析结果表明,决策个体的知识水平、邻接节点数和知识学习率对观点稳定性和收敛时间有正向影响,其中个体知识学习率的影响最显著,但群体达到稳定状态时的观点值是不确定的。仿真实例证明,所提出的观点演化模型可为动态群体决策观点演化和收敛时间的影响分析提供研究基础。In this paper,the model of opinion evolution is put forward to study the influence of individual knowledge learning on the stability of opinion and convergence time in group decision-making.The simulation result shows that the level of knowledge of the individual decision-maker,the number of the neighboring nodes and the rate of knowledge learning have a positive effect on the stability and convergence time of opinion,in which the level of knowledge of the individual decision-maker has the most significant on them.At the same time,the steady state of group opinion is uncertain.The simulation example shows that the dynamic opinion evolution model can be applied to public decision-making,and can provide the research basis for the analysis of the influence on opinion evolution and convergence time in dynamic group decision making.
