Embodiment 1

[0048] In the specific implementation process, a behavior layer model of the crowd simulation evacuation Agent is established.

[0049] Firstly, the present invention needs to design a state update mechanism of the behavior layer, and model the state update mechanism of the behavior layer. For the X state machine, we give its definition:

[0050] X=(Σ,Γ,Q,M,Φ,F,q 0 , m 0 )

[0051] In the formula, ∑ is the input alphabet, which contains the Agent's perception set; Γ is the output alphabet, which is a set of abstract information. During the modeling process, this set of information will output the state and position of the Agent in real time for tracking Agent's behavior information; Q is a non-empty finite set of states, and there are 5 states, namely: safe state, looking for evacuation plan, evacuation, exploring path, passing through exit; M is memory, which saves the current coordinates of Agent, evacuation and evacuation plan, walking speed towards the exit; Φ is a fun...

Abstract

Provided is a multi-agent based population evacuation simulation model. The model includes a behavioral layer model, an emotion layer model and a guidance model; an emotion layer update mechanism anda behavior layer update mechanism are designed based on an X state machine idea, an emotion X state machine is refined, and the guidance model is added; the guidance model has an impact on emotions ofpedestrians, reduces the negative emotions of the pedestrians, helps the pedestrians find outlets, and updates the emotional layer update mechanism while updating emotions; a mechanism that the emotions react on behaviors is proposed, interactions between 'environment-emotions-behavior' are established, data output is calculated in the behavior layer and passed to the emotion layer, and feedbackgenerated by the emotions acts on the behavior layer. By applying the population evacuation simulation model to real life, the model solves the problem that the evacuation of population can be quicklyimplemented if an emergency occurs.

Description

technical field [0001] The invention relates to the technical field of crowd evacuation, and more specifically, to a multi-Agent-based crowd evacuation simulation model. Background technique [0002] my country's economy has achieved rapid development in recent years. There are more and more large buildings such as railway stations, subways, cinemas, and gymnasiums. Urbanization has become the mainstream trend. While the continuous development of the city brings convenience to people's life, the frequency of people's travel is also increasing, followed by the problem of increasing crowd density in public places, especially during rush hours or subway rush hours Period, etc., the crowds in public places are often in a dense state. The architectural design is complex and the flow of people is huge. If an emergency occurs, it will be difficult to quickly evacuate the crowd. In 2014, a large number of citizens and tourists gathered on the Bund of Shanghai to participate in New...
