Research on Personnel Evacuation Problem Based on Cellular Automata Model

Emergency evacuation is a problem of great concern at home and abroad. Aiming at the emergency evacuation problem of personnel, this paper uses MATLAB, Pathfinder and other software to establish an evacuation model based on cellular automata to simulate the different dynamic behaviors that the crowd may exhibit during evacuation under different situations and parameters. In this paper, firstly, several factors affecting the anxiety of the crowd are determined, and three key factors affecting the degree of anxiety of the personnel are screened out by the analytic hierarchy process: the distance from the safe exit, the number of personnel and the emotional infection. Then, a personnel evacuation model based on cellular automata is established, and the influence of the degree of anxiety on the length of evacuation time is analyzed under the influence of each key factor. Finally, by changing the key parameters, the experimental results are affected. Finally, the key parameters that cause the difference in evacuation effect are analyzed.
