考虑基于社会力模型的多出口场馆的人员疏散问题.首先对社会力模型进行改进,包括个体之间的相互作用力和他们的相对位置有关,个体的期望速度随时间变化等.然后,针对多出口情形,定义动态变化的视野范围,综合考虑个体到出口的距离、个体视野范围内的人数和人群密度等因素,建立最优化模型描述个体选择目标出口的过程.最后,仿真结果表明,上述模型可以模拟出多出口的体育场馆中的疏散场景,该模型可用于体育场馆的建设评估及为现场指挥预案的制定提供依据. Consider the problem of evacuation of personnel in multi-exit venues based on social model.Firstly, we improved the social force model, including the interaction between individuals and their relative position, the expected speed of individuals with time, etc. Then, Export, define the dynamic range of vision, and consider the individual’s exit distance, the number of individuals within the field of view and population density and other factors, to establish an optimal model to describe the process of individual choice of target exports.Finally, the simulation results show that the above model This model can be used to evaluate the construction of sports stadiums and provide the basis for the formulation of on-site command plans.
