摘　　要：在元胞自动机模型和行人流模型基础上,解决了飞机疏散模型中的元胞严重冲突问题,实现了模型元胞速度动态可变和对不同出口的流量控制,针对多出口状态下准确地模拟绕过复杂障碍物等要求,建立了基于大型飞机环境特点约束的网格吸引力概率模型,并通过应用某型飞机客舱布局作为算例进行了乘客应急疏散的过程模拟。最后在DELM IA平台下对人员的疏散行为进行建模并实现三维演示验证,模型的仿真过程接近真实情况,仿真结果和现有疏散实验结果相吻合。Based on the Cell Automata Models and Passengers Flow, the issues such as, cells conflicted, velocity transformable dynamically, and the controls of flow in different exits, were tackled. Based on the environment characteristics of the large planes, the gridding model which can simulate the cells rounding complex obstacles accurately under the situation of multiple exits was built. Finally, the process of emergency evacuation was simulated applying an actual cabin layout. And then the simulation process was validated in Delmia system. The result shows that the cells behavior is much close to reality, and the evacuation time is tallied with the empirical formulations.
