Abstract: Based on engineering needs in practice，analyses the main influence factors on personnel evacuation in case of an emergency，presents the emergency evacuation system processing strategy，improves and optimizes the evacuation simulation algorithm，and designs the evacuation model of stochastic cellular automata located nearest to the exit. The experiments show that the model simulates well the relationships among the number of person，the number of obstacles，the exit attribute，evacuation speed，evacuation time and so on. The simulation system provides the effective reference value for architectural design，maximum personnel saturated number and fire plans.

Key words: evacuation, cellular automaton, evacuation simulation
