In order to solve the emergency evacuation problem of personnel in the event of fire explosions, earthquakes, terrorist attacks and other emergencies in densely populated shopping malls, this paper uses Matlab software to stimulate the optimal evacuation path based on improved combined network model. Taking the actual mall as an example, the Pathfinder software is used to verify the optimal path, and the authors find out the optimal evacuation exit and evacuation bottleneck based on a simulation when the mall is overcrowded. By analyzing the evacuation bottlenecks under different periods, the authors conclude that: first, the optimal evacuation path is better than simply select the the closest exits; second, evacuees have a herd mentality; third, when the density of the personnel on the fourth layer exceeds 0.59 people/m2, a stampede will occur during the evacuation. Overall, this study provides a useful supplement to the model of evacuation behavior.
