Embodiment 2

[0142] Embodiment 2 of the present invention provides a crowd evacuation simulation method for regulating and optimizing negative emotions based on knowledge dissemination.

[0143] Firstly, a cooperative communication model of emotion and knowledge is proposed to explore the process of emotional infection and knowledge diffusion and the influence of knowledge on negative emotions. In this model, a multi-network of emotion and knowledge is constructed, and a mathematical model is used to describe the propagation process of emotion and knowledge in the multi-network. The impact of knowledge on negative emotions was quantified using the Siminoff psychological model.

[0144] Secondly, in order to regulate the moderate negative emotions of the crowd and improve the evacuation efficiency, a psychology-based emotion and speed model was proposed to quantify the relationship between individual negative emotions and movement speed.

[0145] Finally, a heuristic algorithm-artificial b...

Abstract

The invention provides a crowd evacuation simulation method and system considering the influence of knowledge propagation on negative emotions, and belongs to the technical field of crowd evacuation simulation. The method comprises the steps of constructing a knowledge-negative emotion infection multi-propagation network, determining the negative emotion intensity value of an individual, and determining the total knowledge quantity received by the individual; determining a negative emotion change value in combination with a Simnov psychology model; constructing an emotion-speed model; optimizing and solving the emotion-speed model by utilizing an artificial bee colony algorithm, and determining an optimal position enabling the average movement speed of the crowd to be maximum; and realizing crowd evacuation simulation according to the optimal position. The emotional infection and knowledge propagation process and mutual influence thereof are described, the influence of knowledge on negative emotional infection is quantified, the relationship between negative emotions and the movement speed is provided, the crowd evacuation efficiency problem is described as the speed maximization problem, the optimization problem is completed through a heuristic artificial bee colony algorithm. A visual negative emotion regulated crowd evacuation analogue simulation result is realized.

Description

technical field [0001] The invention relates to the technical field of crowd evacuation simulation, in particular to a crowd evacuation simulation method and system considering the impact of knowledge dissemination on negative emotions. Background technique [0002] In recent years, the rapid economic development has led to more and more large shopping malls and shopping centers. When an emergency occurs in these places, how to efficiently carry out crowd evacuation becomes the most worrying issue. Emotion plays a crucial role in crowd decision-making behavior, especially on the speed of individual movement. Psychological research has shown that individuals move faster in negative emotional states than in positive emotional states, but remain stationary in extremely negative emotional states. Then, how to control the moderate negative emotions in the crowd in a critical situation, so as to efficiently evacuate the crowd is a challenging problem. [0003] However, individu...
