Abstract:

By studying a system for complex multilevel collaboration process based crowd evacuation, we can exactly simulate the crowd evacuation in emergency. In this paper，the crowd evacuation in complex obstacles in a multilevel building has been simulated based on the cellular automata improvement and optimization. Besides，the individual characteristics，the following behavior，et al.，have been also considered. The results give the efficiency of crowd evacuation with the parameters of following behavior，the location of obstacles and exits.The proposed model can effectively simulate the crowd evacuation process in emergency at a largescale public place. The simulation results have real reference significance for the crowd evacuation scheme in multilevel building emergency under the complex environment and the characteristics of people.

Key words: crowd evacuation;multilevel collaboration;cellular automata;individual characteristics;following behavior
