Simulate crew's evacuation by using cellular automaton and artificial intelligence theory. Study the action of auto-path searching and the rule of crew's movement when the density of the crew reached a numerical value under the situation of “area division”. We find out crew's action of obstacle avoiding and path searching under the condition of Area division is more likely to match the reality. Compared with the individual movement, crew's movement proved that with the same computer resource supplied, the number of evacuated crew has increased, at the same configuration of crowd,the time of evacuation does not change a lot. The result indicates that Area division and “simulation of crew's movement” can reduce the impact on the result and in the meantime ensure the result's validity. It is a practical measure to simulate an urgent evacuation under a real situation.
