Abstract

The motion of a group of people is modeled for an emergency where it is necessary to evacuate people from a building of complicated structure as quickly as possible without stampede. To build the model, it is important to determine which information is available for a current analysis of the situation and which parameters can be used as controls. A macroscopic model of crowd flows is considered in which split factors in separate parts of the area are the control parameters. A scheme for calibrating the model using an auxiliary microscopic model is proposed, in which the behavior of individual persons is considered. The problem of estimating the minimum possible time needed to perform evacuation is solved. An algorithm for achieving suboptimal control is provided.

疏散期间建筑物中的人群流量控制

摘要

一群人的运动是为紧急情况建模的，在紧急情况下，必须尽快将人们从复杂结构的建筑物中撤离而不会踩踏。为了建立模型，重要的是确定哪些信息可用于当前情况分析，哪些参数可用作控制。考虑人群流动的宏观模型，其中该区域不同部分的分裂因子是控制参数。提出了一种使用辅助微观模型校准模型的方案，其中考虑了个人的行为。解决了估计进行疏散所需的最小可能时间的问题。提供了一种用于实现次优控制的算法。
