团体行为对航站楼内流感传播扩散的影响分析

Analysis of the Group Behavior's Influence on the Spread of Influenza in Terminal

针对团体行为对航站楼内流感传播扩散的影响,运用社会力模型建立基于个体接触的易感者-潜伏者-感染者-移出者(suspicious expoced infected removed,SEIR)改进模型。以某航站楼为例,模拟航站楼内流感的传播扩散过程,定量分析团体行为对楼内流感扩散的影响。实验结果表明,团体行为对进港流程中流感扩散的影响较离港流程大,造成的二者感染者数量增幅分别为47.7%和14.2%。

An individual contact based SEIR model is developed with social force to analyze the influence im- posed by group behavior on the spread of influenza in terminal. The model is conducted on a terminal to quantita- tively analyze the influences. Experiments demonstrate that group behavior generate more effect of arrival than that of departure. The amount of passengers infected in arrival and departure increase by 47.7% and 14. 2% respec- tively.
