Embodiment 1
[0081] Such as figure 1 As shown, Embodiment 1 of the present invention provides a crowd evacuation simulation system considering the impact of knowledge dissemination on negative emotions. The system includes:
[0082] The first building block is used to construct knowledge-negative emotion infection multiple transmission network;
[0083] The calculation module is used to infect the multiple transmission network based on knowledge-negative emotion, determine the individual's negative emotion intensity value, and determine the total amount of knowledge received by the individual according to the negative emotion intensity value; according to the received total amount of knowledge, combined with Siminov A psychological model to determine the value of the change in negative emotions;
[0084] The second building block is used to construct an emotion-speed model according to the negative emotion intensity value and the negative emotion change value;
[0085] The optimization m...
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.
[0210] Embodiment 3 of the present invention provides a computer device, including a memory and a processor, the processor and the memory communicate with each other, the memory stores program instructions executable by the processor, and the processor calls the The above-mentioned program instruction executes the crowd evacuation simulation method considering the impact of knowledge dissemination on negative emotions as described above, including the following process steps:
[0212] Based on the knowledge-negative emotion infection multiple transmission network, determine the individual's negative emotion intensity value, and determine the total amount of knowledge received by the individual according to the negative emotion intensity value; according to the received total knowledge amount, combined with Siminov's psychological model, determine Negative mood change value;
[0213] Constru...

Abstract
The invention provides a crowd evacuationsimulation method and system considering the influence of knowledge propagation on negative emotions, and belongs to the technical field of crowd evacuationsimulation. 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 evacuationsimulation 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 heuristicartificial 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...
