Abstract: Various disasters or accidents often reoccur in the process of evacuation. In order to solve the problem of evacuation in multiple disasters, a perceptual model for evacuation was proposed based on multi-agent technology. By guiding the decision and action of people with mathematical model of disaster and individual perception model, the crowd evacuation stimulation was combined with environment disaster model. It stimulated the perceptive functions such as visual sense, sense of smell, and auditory sense with ray method, gas molecular diffusion formula, and the theory of sound transmission. It analyzed the information of people through stress reaction model and compound decision model. In the process of evacuation, the travelling speed of people was worked out with the calculation model of velocity, the mental and physiological effect. It's proved that the crowd Evacuati-on model is able to present the situation in multiple disasters veritably.
