摘要
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 is an evacuation computer model on the basis of geometric method and intellectualized aim distinguishing. This model can express the space of buildings and the body of evacuees through some simple geometry elements ; it can also simulate the velocity change of evacuees through collision detection and position adjustment algorithms. By setting target classification and condition decision rules, the choice of evacuation route can be simulated and the group effects can be reflected. To analyze the accuracy of GAEvac, two experiments with different velocity changes and route choices were simulated and the resuhs were compared. Finally, an illustration was made, which shows that this model is of practicability and referring value
