基于多Agent的人员应急疏散模型研究

Research on personnel emergency evacuation model based on multi-Agent

在分析、比较现有疏散仿真模型的基础上,考虑到Agent的智能性、自治性、交互性,提出基于多Agent的人员应急疏散模型,该模型中疏散空间被分成相等的正方形,每个行人有包括静止在内的9个运动方向。个体在选择疏散出口的决策过程中,综合考虑个体到出口的距离、视野范围内的人员、障碍个数及其相关密度。在仿真中,考虑出口的数量位置和出口的宽度,结果表明,增加出口的数量和出口的宽度,疏散过程中加入引导员能够有效地提高疏散效率。该研究对于制定有效的应急疏散方案,具有一定的实际参考意义。

On the basis of analyzing and comparing the existing evacuation simulation models,a multi-agent-based emergency evacuation model is proposed in consideration of the intelligence,autonomy and interactivity of agents. In this model,the evacuation space is divided into equal squares,and each pedestrian has 9 directions of motion,including the static one. In the decision-making process of individual choosing the evacuation exit,the distance from individual to exit,the number of personnel and obstacles within the scope of vision and the relevant density are comprehensively considered. In the simulation,in consideration of the quantity,position and width of the exit,the results show that the evacuation efficiency can be improved effectively by increasing the quantity and width of the exit,and adding the guide in the evacuation process. The research has certain practical reference significance for the formulation of effective emergency evacuation planning.
