摘要
分析了紧急情况下人员疏散的难点,提出了应急系统人员疏散策略,设计了一种基于CA的人员疏散模型.通过模型仿真,分析模型中相关参数对疏散效果的影响,在此基础上对人员疏散模型中地场方法进行改进,模拟结果表明,基于CA的应急疏散仿真能够很好的模拟建筑内人员应急疏散行为及紧急事件的发展情况.同时该仿真方法具有直观性、灵活性和可扩展性,为应急管理研究提供了一个很好的研究思路.
In this paper, we analyze the difficulties of people evacuation under emergency, propose an evacuation strategy of an emergency system and design an evacuation model based on CA. And through model simulation, we analyze the effects of the relevant parameters on evacuation and improve field method. Finally, we successfully apply this CA model to simulate the evacuation results in an example. And the simulation result indicates that the emergency evacuation simulation based on CA can simulate evacuees＇ behavior under emergency in a building and predict the future development of emergency event. Further, the immediacy, the flexibility and the expendability of this method can provide a good idea for emergency management research.
