突发社会安全事件下大众羊群行为的演化模拟及行为族现象

基于行为的传播性和保持性,对突发社会安全事件下的大众羊群行为利用元胞自动机进行了模拟.从各类行为者均匀混合的初始条件开始,得到了非常接近社会实际情况的行为族现象.研究结果表明,只要各种行为的比例相差不过于悬殊,羊群行为并不能导致许多行为的消失而使群体中只存在一种行为,而是许多类型的行为以行为族的方式同时存在.

Simulation on herd behaviors and behavior groups in case of exigency of social safety by use of cellular automata model

Cellular Automata model was improved to simulate the herd behavior of people in case of exi- gency of social safety,in consideration of the influence and insistence of the behaviors.Starting with the initial state of uniformly mixed behaviors,the behavior groups were produced.As long as the propor- tions among the different kinds of behaviors are not far from equilibrium,the herd behavior can not lead to the state of only one behavior left and others dissipated,but to the state of many kinds of behaviors existing in the form of behavior groups.
