摘要
在群决策研究中,由于决策者的私有信息难以观察,致使无法有效地区分真实从众行为和虚假从众行为.针对这一问题,首先基于从众角度将决策行为分为三类,在此基础上,提出了一种基于元胞自动机的群决策从众行为演化模型.该模型能够模拟群体的决策行为,揭示伪从众行为对群决策的影响.仿真实验结果表明从众偏好、群体交互次数和群体规模对三类从众行为存在明显的影响,并有规律可循.
In the study of group decision, it is difficult to distinguish between genuine conformity and spurious conformity for the reason that the decision-maker's information is hard to be observed. In response to this problem, the paper here first divides the decision behavior into three categories from the view of conformity, and then puts forward an evolutionary model for group decision conformity on the basis of cellular automata. This model can simulate group decision behavior and reveM spurious conformity's influence on group decision. The simulation experiments show the conformity preference, group communication times and group scale have influences on the three conformity behaviors.
