基于GAMA平台的多智能体应急疏散仿真模型

Multi-agent simulation of emergency evacuation based on GAMA Platform

应急疏散的研究对象是一个复杂的社会系统,利用多智能体模型可以有效模拟人群复杂的社会行为。将多智能体模型应用于应急疏散领域,设计5种类型的智能体实体,构建多智能体应急疏散仿真模型,从被疏散个体的相互作用行为入手,研究整个被疏散群体的行为特征。基于GAMA平台,实现以矢量地理空间数据为基础的多智能体应急疏散仿真模型,通过仿真实验,动态呈现整个应急疏散过程。对灾害、突发事件应急疏散指挥,应急疏散设施建设、城市规划设计等工作具有重要的意义。

T he object of emergency evacuation is designed as a complex social system .Sophisticated human social behaviors can be simulated through multi‐agent‐based models .This proposes a multi‐agent‐based model applied to the emergency evacuation behaviors in real word .An multi‐agent‐based model that consists five types of agent entities is developed to characterize the individual behaviors and the features of a group .The model is designed and implemented on the GAMA Platform (GIS & Agent‐based Modeling Architecture) .The results present a dynamical emergency evacuation process that will provide suggestions about command and regulation of emergency evacuation in disasters and planning in urban construction .
