GAEvac模型是基于几何方法和目标智能判别的人员疏散计算机模型,该模型针对建筑物和人员的特点,建立以几何元素表示的建筑物空间和人员体型模型,通过碰撞检测和位置调整的算法,模拟疏散中个体人员的速度变化和移动方向选择。通过设置分级目标和条件决策规则,模拟疏散过程中的人员路径选择,疏散过程中的群体效应得以体现。通过速度变化和疏散路径选择模拟实验,对GAEvac模型模拟的结果进行了对比分析。最后,通过对实例的模拟,验证了GAEvac模型的应用效果。
GAEvac model is an evacuation computer model based on geometric method and target intelligent discrimination. The model builds space and personnel body model based on the characteristics of buildings and personnel. Through the algorithm of collision detection and position adjustment, the model is simulated Evacuation in the individual changes in speed and direction of choice. By setting the classification target and the decision rules of the condition, the simulation of the path selection during the evacuation process shows the group effect in the evacuation process. Through the simulation of speed change and evacuation route selection, the results of GAEvac model simulation are compared and analyzed. Finally, the application of GAEvac model is verified through the simulation of the examples.
