具有差异延迟期的群体观点一致行为研究

Research on the Behavior of the Group Opinion's Consistency with Differential Latency

研究个体在观点变化过程中存在延迟期对群体观点收敛时间和一致性的影响。从复杂系统的角度分析了群体观点演化的自组织特性,包括内部个体的对外界观点考虑和吸收的开放性,以及个体本身在观点变化过程中间存在差异延迟的因素。在此基础上,提出了一种开放性个体存在观点变化延迟期的动态群体观点演化模型。模型中的开放性是群体与外界产生信息交互的先决条件,并通过群体内部个体的特性体现出来。与传统研究中个体始终处于积极与相近观点个体发生交互不同的是,提出延迟期的概念,处于延迟期的个体自我封闭,群体结构通过这种状态的突变发生变化。借助于计算机仿真发现,差异延迟对群体的影响显著。在相同时间内,群体观点的一致性降低;不同延迟差异下,稳定性群体结构的波动也出现变化,并达成一致所用时间延长,结合实例分析验证模型的实效性。

The paper discusses the latency affect opinion convergence time and consistency of group in the process of individual＇s opinion changing. It analyses self-organization of the groups opinion from the perspective of complex systems, including the openness of individual＇s considering and absorbing to the outside opinions, as well as the individuals themselves in the process of the opinion changing with different delay factors. Based on this,we propose a dynamic group evolution model. The openness of the model is precondition to information exchange of the groups and the outside world which was reflected by individual characteristics. In the traditional research,individuals are always positive communicate with other similar opinions. We proposed the concept of latency when individuals are self-enclosed, groups structural was changed under the mutations of this state. By computer simulation, differential latency has remarkable influence on the individuals. The groups~ consistency will be reduced at the same time; the fluctuations of the stability of population structure will change when latency is differential, and takes more time to reach the consistence. The example shows the effectiveness of the model.
