摘要
介绍背景场模型和格子气模型的原理,采用格子气模型和背景场模型对障碍物双出口房间内的行人疏散过程进行模拟。以背景场模型中的概率确定行人运动的主方向,以格子气模型中的局部运动规则描述行人的具体运动规则,联合全局影响和局部规则,设置不同出口位置的三个场景分析出口位置对人员疏散效率的影响。
The principle of background field model and lattice gas model were introduced. These two models were used to simulate the person evacuation in room with two exits and obstacles in it. The probability in background field model was used to determine the direction of person movement, and the local movement rule in lattice gas model was used to describe the person movement. Combined with the overall impact and local rule, three scenarios with different the influence of exits location exits location were set to analyze on the evacuation efficiency.
