Research And Implementation Of Personnel Evacuation Simulation Model Under The Environment Of Multiple Disasters

The issue of personnel evacuation, which is an important safety factor in modern society, is receiving more and more attention. Aiming at the evacuation of people under urgent circumstances, and combining with the situation where there may be multiple disasters in the process of evacuation, a simulation model of personnel evaluation based on agent under the circumstance of multiple disasters is established to study the microscopic features and behavior rules of personnel evacuation.In order to describe the simulation of personnel evacuation under multiple disastrous environment, the simulation study of disaster and the study of behavior characteristics of evacuators are combined to construct a mathematical model of disaster and individual perceptual model to drive personnel’s decision-making and behaviors in the paper. The mathematical model of disaster, which mainly analyzes disasters such as fire, explosion, and diffusion of poisonous gas, is quantizing the attribute of disaster according to its characteristics. The individual perceptual model is achieving the personnel’s perceptive functions like vision, smell and hearing through algorithm like physical ray method, formula of gas molecular diffusion and principle of sound transmission, and achieving the personnel’s function of information analysis by models such as stress response and compound decision. Besides, a model of speed constraint of influencing factors including the degree of crowdedness, psychology and physiology is set up to calculate the speed of personnel in the process of evauation.A simulation system of personnel evacuation under multiple disasters is developed according to the algorithm of this model, and a simulation test of personnel evacuation is carried out on the system. The simulation result shows that this system well reveals the influence of disastrous environment on personnel evacuation, while the comparatively authentic effect of personnel evacuation simulation reflects the scientificity and rationality of this personnel evacuation model.
