基于演化博弈理论的疏散动力学研究

为了研究个体合作行为对行人整体疏散效率的影响，结合元胞自动机与社会力模型对疏散系统动力学与“合作行为”的共演化进行了研究，提出了基于演化博弈理论的疏散动力学研究方法。采用元胞自动机模型为基础仿真框架，利用社会力模型来表征行人间的心理斥力，通过演化博弈实现疏散个体策略更新。仿真实验结果表明：当博弈增益系数超过一定阈值时群体的稳定合作比率会急剧上升，且合作行为能有效促进疏散效率。

Evacuation Dynamics Research Based on Evolutionary Game Theory

In order to study the impact of individual cooperative behavior on the overall pedestrian evacuation efficiency, combined with cellular automata and social force model, the co-evolution of evacuation system dynamics and "cooperative behavior" is studied, and an evacuation dynamics research method based on evolutionary game theory is proposed. The cellular automata model is used as the basic simulation framework, and the social force model is used to represent the psychological repulsion among the practitioners. The evacuation individual strategy is updated through evolutionary game. The simulation results show that when the game gain coefficient exceeds a certain threshold, the stable cooperation ratio of the group will rise sharply, and the cooperative behavior can effectively promote the evacuation efficiency.
