摘　　要：在飞机应急撤离的仿真模拟中,国内多采用元胞自动机模型模拟疏散的人群,该模型计算较快,但把疏散者视为同样的粒子,忽略了个体差异,因此与实际撤离情况存在差异。采用智能体模型,建立个人的行为规则;采用适合飞机应急撤离的A*算法选择估值函数,建立人物模型,针对波音737-700飞机客舱进行应急撤离过程的仿真模拟,并与前人实验结果和权威软件airEXODUS仿真结果进行验证对比。结果表明:本文算法的仿真结果与实验结果接近,更接近真实疏散情况。In the simulation of emergency evacuation of aircraft,the cellular automaton model is mostly used to simulate evacuated people.This model is faster in calculation but regards the evacuees as the same particles,ignoring individual differences,so there is a difference from the actual evacuation situation.In this paper,the agent model is used to establish personal behavior rules,combined with the A*path-finding algorithm,a valuation function in the A*algorithm suitable for aircraft emergency evacuation is proposed,and a character model is established.The simulation of the emergency evacuation process of the cabin of a certain type of Boeing 737-700 aircraft is carried out,and compared with the previous experimental results and the authoritative simulation software airEXODUS.The results show that the simulation results of the proposed algorithm are close to the real experimental results,and closer to the real evacuation situation.
