Abstract

The invention relates to a simulation method and system for crowd evacuation based on a multi-bee colony algorithm. The method comprises the steps of setting evacuation scene parameter information, creating an evacuation scene model and a character model, and importing the character model into the evacuation scene model, wherein the evacuation scene model serves as the environment space of the crowd evacuation, and the character model serves as an evacuation crowd; extracting semantic information of the evacuation scene model, setting evacuation crowd parameter information under an evacuation scene, and conducting crowd initialization according to the evacuation crowd parameter information; dividing the evacuation crowd into groups, selecting a leading bee out from each group, adopting the multi-bee colony algorithm and adding auxiliary population to plan macroscopic paths, adopting a social force model to guide the movement of microscopic population, obtaining a final crowd evacuation path to conduct the simulation of the crowd evacuation. Through the adoption of the method, the simulation of the crowd evacuation in complex scenes can be really and effectively achieved, the evacuation time is shortened, the utilization rate of exits is increased, and the method can provided help for real evacuation rehearsals.

Description

technical field [0001] The invention belongs to the technical field of crowd evacuation simulation, and in particular relates to a crowd evacuation simulation method and system based on a multi-bee colony algorithm. Background technique [0002] In recent years, with the frequent occurrence of various fire accidents and emergencies, more and more attention has been paid to the safe evacuation simulation of emergencies in public places where crowds gather. Simulating the crowd evacuation behavior in the real scene has important social significance. It can help the emergency department to formulate corresponding emergency plans, guide the design of the scene, avoid disasters, and reduce casualties. Using computer simulation technology for scene modeling, path optimization, and crowd movement behavior modeling can minimize the cost while achieving the best evacuation drill effect. Therefore, computer simulation has become the most important method to study crowd evacuation und...
