基于元胞自动机的多出口人员疏散模型的研究

On multi-exit occupant evacuation model based on cellular automaton

在对多出口场所紧急疏散过程的研究中着重考虑个体在决策时的主观智能作用,通过引入目标方向密度概率,出口影响因子概率,移动方向校正因子,建立了基于元胞自动机的多出口人员疏散模型.通过对教室中学生的疏散行为的模拟仿真,表明所建模型在考虑上述三个因素时,模拟疏散的过程和结果更加合理,模型具有较好的实用性.

This paper considers the occupant＇s intelligence effect on decision-making in the study of the multi- exit urgent evacuation process. The multi-exit occupant evacuation model based on cellular automaton is established with the introduction of the probability of the target direction＇s density, the probability of the exit＇s influential factor and the movement direction＇s correction factor. The analog simulation of the student＇s evac- uation behavior in the classroom proves that the analog evacuation process is more reasonable and practical when the three above mentioned factors are considered in the process of modeling.
