论文摘要
我们提出了一个基于拉塔内社会影响理论的意见动力学模型。该模型中的演员是异质的，除了意见外，其特征是他们的说服力和支持程度不同。该模型的两种和三个初始意见测试在参与者之间随机分发。我们研究了参与者之间的噪音（行为随机性）和信息流如何影响意见的形成和传播。我们的主要研究涉及意见形成的过程，并从描述系统中有两个和三个意见的信息的参数和流动来找到系统的阶段。结果表明，意见形成和传播都受到参与者之间信息流的影响（i）参与者之间的信息流（参与者之间的有效互动范围）和（ii）噪音（采用意见的随机性）。噪音不仅会导致意见障碍，而且还会在某些条件下促进共识。
We propose an opinion dynamics model based on Latané's social impact theory. Actors in this model are heterogeneous and, in addition to opinions, are characterised by their varying levels of persuasion and support. The model is tested for two and three initial opinions randomly distributed among actors. We examine how the noise (randomness of behaviour) and the flow of information among actors affect the formation and spread of opinions. Our main research involves the process of opinion formation and finding phases of the system in terms of parameters describing noise and flow of the information for two and three opinions available in the system. The results show that opinion formation and spread are influenced by both (i) flow of information among actors (effective range of interactions among actors) and (ii) noise (randomness in adopting opinions). The noise not only leads to opinions disorder but also it promotes consensus under certain conditions.
