考虑情绪感染机制的实验室人员疏散模型
A laboratory personnel evacuation model considering the mechanism of emotional contagion
摘要
Abstract
[Objective]Efficient personnel evacuation during sudden disasters such as fires and earthquakes is critical to life safety.Although existing studies have investigated the influence of emotional contagion on evacuation time,most focus on buildings with a single exit and neglect layouts with multiple exits.Moreover,the coupled effects of instantaneous panic fluctuations across scenarios and gradual emotional evolution over time are rarely considered.To address these gaps,this study develops a personnel evacuation model that incorporates dynamic emotional changes and contagion mechanisms to analyze their impacts on evacuation performance.[Methods]A personnel evacuation model incorporating emotional contagion was constructed by coupling a cellular automata framework with a susceptible-infected-susceptible(SIS)model.A cellular automata-based evacuation scheme accounting for individual emotional states in emergency scenarios was designed,and the corresponding simulation program was developed in MATLAB.Simulation and verification were conducted using the National Experimental Teaching Demonstration Building for Air Traffic Control at Civil Aviation University of China as the application scenario.Based on an evacuation plan that did not account for emotional contagion,the effects of panic emotions on overall evacuation time were analyzed,with particular attention to key parameters,including the emotional threshold and the emotional self-attenuation coefficient.[Results]The validity of the proposed evacuation model was first verified by comparison with results from the Pathfinder simulation software.Without incorporating emotional contagion,the difference in evacuation time between the proposed model and Pathfinder was only 1.5%.After introducing the panic emotion mechanism,evacuees in a panicked state often lost rational judgment and exhibited behaviors such as acceleration,collisions,and conflicts.These behaviors propagated through emotional contagion,adversely affecting surrounding individuals and resulting in a 15.8%reduction in evacuation efficiency,corresponding to a notable increase in total evacuation time.[Conclusions]The results indicate that incorporating emotional contagion leads to congestion and conflict behaviors in high-density areas such as exits and staircase entrances,thereby reducing evacuation efficiency compared with scenarios without emotional effects.As the emotional threshold increases,evacuation time initially decreases and then stabilizes.A higher emotional self-attenuation coefficient promotes faster emotional recovery among panicked individuals and a gradual reduction in the number of panicked evacuees,whereas a lower coefficient causes the number of panicked individuals to first increase and then decrease.These findings highlight the importance of considering emotional dynamics in evacuation modeling and emergency management.关键词
