1.程序功能描述

出口在人员的视野范围内时，该元胞选择朝向引导点的方向运动。出口不在人员的视野范围内时，作随机运动，8个方向的运动概率相等。引导点可设在过道中间等地方，出口都是引导点。

1. 当多个元胞同时竞争同一个格点时，每个元胞以50%等概率进入，没有进入的保持静止.

2.运动人员以5%概率静止，即下一时间步不动.

3.开始疏散时所有人员是以正态分布的概率开始运动，而不是同时运动.

4.本算法原理

在超市这类大型商业建筑中，火灾发生后，烟雾会在短时间内迅速扩散。烟雾的传播主要受到热量释放、空气流动（包括自然对流、强制通风）、建筑布局（如走廊、隔断、开口）以及材料燃烧特性的影响。烟雾不仅阻碍视线，而且含有有毒有害物质，对被困人员构成生命威胁。烟雾蔓延可以通过火灾动力学模型（如热层流方程、组分传输方程）进行模拟分析，如使用FDS（Fire Dynamics Simulator）软件。

基本烟雾扩散模型都是基于流体方程建模的：
