Embodiment 1

[0081] like figure 1 As shown, Embodiment 1 of the present invention provides a crowd evacuation simulation system considering the influence of knowledge dissemination on negative emotions, and the system includes:

[0082] The first building block is used to construct the knowledge-negative emotion infection multiple propagation network;

[0083] The calculation module is used to determine the negative emotion intensity value of an individual based on the knowledge-negative emotion infection multiple communication network, and determine the total amount of knowledge received by the individual according to the negative emotion intensity value; Psychological models to determine the value of negative mood changes;

[0084] The second building module is used to construct an emotion-velocity model according to the negative emotion intensity value and the negative emotion change value;

[0085] The optimization module is used to optimize and solve the emotion-speed model by using...

Embodiment 2

[0142] Embodiment 2 of the present invention provides a crowd evacuation simulation method based on knowledge dissemination and optimization of negative emotion regulation.

[0143] Firstly, a model of collaborative communication of emotion and knowledge is proposed to explore the process of emotional contagion and knowledge transmission and the influence of knowledge on negative emotions. In this model, a multiple network of emotion and knowledge is constructed, and a mathematical model is used to describe the dissemination process of emotion and knowledge in the multiple 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, an artificial bee ...

Embodiment 3

[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 that can be executed by the processor, and the processor calls the The above-mentioned program instruction executes the above-mentioned crowd evacuation simulation method considering the influence of knowledge dissemination on negative emotions, including the following process steps:

[0211] Construct knowledge-negative emotion infection multiple communication network;

[0212] Based on the knowledge-negative emotion infection multiple transmission network, the negative emotion intensity value of the individual is determined, and the total amount of knowledge received by the individual is determined according to the negative emotion intensity value; negative emotion change value;

[0213] According to the negative emotion intensity value and the negative emotion change val...

Abstract

The invention provides a crowd evacuation simulation method and system considering the influence of knowledge dissemination on negative emotions, belonging to the technical field of crowd evacuation simulation. Combined with Siminov's psychological model, determine the change value of negative emotions; build an emotion-velocity model; use artificial bee colony algorithm to optimize and solve the emotion-velocity model, and determine the optimal position that maximizes the average movement speed of the crowd; Realize crowd evacuation simulation based on optimal location. The invention describes the process of emotional infection and knowledge dissemination and their mutual influence, quantifies the impact of knowledge on negative emotional infection, proposes the relationship between negative emotions and movement speed, and describes the problem of crowd evacuation efficiency as a speed maximization problem. The heuristic artificial bee colony algorithm completes the optimization problem, and realizes the simulation results of the crowd evacuation simulation of visual control of negative emotions.

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 influence 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 emergencies occur in these places, how to efficiently evacuate people becomes the most worrying issue. Emotions play a crucial role in the decision-making behavior of crowds, especially on the speed of individual movement. Psychological studies have shown that individuals move faster in negative emotional states than in positive emotional states, but in extremely negative emotional states, individuals become still. So, how to control the moderate negative emotions in the crowd in a critical situation, so as to evacuate the crowd efficiently is a challenging problem. [0003] However, indi...
