　　报告内容摘要： Crowd evacuation under emergency is a complex system engineering. The existing crowd evacuation simulation methods do not consider the relationship between the crowd and the influence of the group on the movement. Although Helbing and Molnar proposed a social force model based on Newtonian mechanics to simulate crowd behavior, it can reproduce some phenomena, such as "faster and slower," and the arch at the exit. But it has simplified the behavior of pedestrians, without considering the relationship between the crowd and the formation of groups on the impact of movement. In order to solve the above problems, we have improved the social force model, based on the original driving force, the force between people, the forces between people and obstructions, and the disturbing force, we add a group attraction force. Simulation results illustrate the effectiveness of this method.
