基于工程实践需要,分析了紧急情况下人员疏散的主要影响因素,提出了应急系统人员疏散处理策略,改进和优化了人员疏散仿真算法,设计了基于出口距离最近的随机元胞自动机的人员疏散模型。实验表明,模型较好地仿真了人员数、障碍物数、出口属性、疏散速度、疏散时间等因素相互之间的关系。仿真系统可为建筑结构设计、最大人员饱和数、消防预案提供参考。

Based on engineering needs in practice,analyses the main influence factors on personnelevacuation in case of an emergency,presents the emergency evacuation system processing strategy, improves and optimizes the evacuation simulation algorithm,and designs the evacuation model ofstochastic cellular automata located nearest to the exit. The experiments show that the model simu-lates well the relationships among the number of person,the number of obstacles,the exit attribute, evacuation speed,evacuation time and so on. The simulation system provides the effective referencevalue for architectural design,maximum personnel saturated number and fire plans.
