Modeling and simulation research on diffusion of the public voice

The public opinion formation is becoming of a strategic importance at all levels of society. Public voice, a consequence of an asymmetrical informational structure, is interwoven by viewpoints of many individuals involved in the issue. The control and possible handling to manipulate information are now major issues in social organizations, including economy, politics, fashion, and even personal affairs. This paper focuses on simulation of the public voice diffusing based on the social mechanisms at individual level. At first, an analysis was performed to establish a multi-agent-based model analogous to a cellular automata model; it incorporated the variables of individual characters and other individualspsila impact to describe the thinking process of individuals, when they were confronted with the public voice. The attributes and hypothesizes referred in the model would be detailed in this section. Then another analyses followed further examine the functions of some parameters and mechanisms in the public voice forming, based on simulation experiments and sensitivity analysis. Finally, exploratory discussions and limitations on the model were presented.
