基于双层规划混合模型的人员疏散问题研究

Personal Evacuation Based on Bi-Level Programming Mixed Model

以多粒子智能体模型为主研究了在一定空间环境下的人员疏散问题。结合双层规划思想合理的描述了不同生理特性行人的不同感知和决策,定量阐述了局部决策与整体行为的相互影响关系,并通过计算机仿真模拟研究群体结构、不同位置出口宽度及危险源对疏散时间和人员受伤情况的影响。结果表明：疏散时间平均变化率和受伤数量变化率呈正相关性,所有出口宽度只有在0~1 m内的增加才会改善受伤情况,危险源对整体疏散效果的影响和对小孩群体的影响基本一致。

The personnel evacuation in certain environment was mainly studied in multi-particle agent model,which combined with bi-level programming to rationally describe different perception and decision of evacuees who had different physiological characteristics. And the interactions between local decision and global behavior were quantitatively described. The influence of group structure,the width of different exits and dangerous source on the evacuation time and the number of injured was studied by computer simulation. The results indicate that the positive correlation between the average change rate of evacuation time and the change rate of the injured is existed; the width of all exits arranging from 0 to 1 meter can improve the status of injured,and the influence of dangerous source on the whole evacuation is basically consistent with that on the children.
