Complex crowd evacuation behavior simulation method based on self-adaption intelligent agent model

Abstract

The invention discloses a complex crowd evacuation behavior simulation method based on a self-adaption intelligent agent model. The self-adaption intelligent agent model is adopted for defining four different types of attributes for each intelligent agent and can make escaping routes for each intelligent agent in a self-adaption mode according to the environment change, and therefore the self-adaption intelligent agent model has a better environmental change resisting capability. An ordinary self-adaption intelligent agent model based on a CPU platform can not deal with the complex crowd evacuation problem; a GPGPU multi-thread method based on a CUDA is adopted for developing a parallel simulation algorithm, the parallel computing thought is infused into the algorithm, and the executing efficiency of the self-adaption intelligent agent model is greatly improved while the algorithm effect is kept. Experiments prove that the method has better efficiency and usability in the actual large-scale complex crowd evacuation problem.

Description

technical field [0001] The invention belongs to the technical field of simulation modeling and relates to a complex crowd evacuation simulation method, in particular to a complex crowd evacuation behavior simulation method based on an adaptive agent model. Background technique [0002] Emergency plans refer to emergency management, command, and rescue plans for emergencies such as natural disasters, major accidents, environmental hazards, and man-made sabotage. It can effectively improve the ability of enterprises and institutions to respond to environmental emergencies, and minimize the losses caused by environmental emergencies to personnel, property and the environment. The development of emergency plans has long been the focus of research by government agencies, social activists, physicists and computer scientists. Crowd emergency evacuation is an important branch of emergency plan, which plays an important role in ensuring personnel safety. [0003] Many existing rese...

AI Technical Summary

Problems solved by technology

[0006] On the other hand, some existing CPU-based methods are greatly limited in large-scale complex crowd evacuation

The existing methods based on the agent model cannot deal with large-scale and high-complexity crowd evacuation problems. (1) The scalability of the existing algorithms is very poor. With the increase of the number of individuals, the increase of algorithm nodes greatly improves the calculation node load

(2) The correlation calculation between individuals will become more and more difficult as the number of individuals increases
