Group evacuation simulation system and method by combining artificial bee colony and social force model

Abstract

The invention discloses a group evacuation simulation system and method by combining an artificial bee colony and a social force model. The method comprises the following steps: acquiring an evacuation scene parameter to construct an evacuation scene three-dimensional model; finding all exits of the evacuation scene in the three-dimensional model; dividing to-be-evacuated crow in the evacuation scene into a plurality of groups according to the individual-to-individual relation and the position from the exit, screening the individual closest to the exit position in each group as a leader of each group; using each exit of the evacuation scene as the food source, and the leader as the leader bee in the group, thereby establishing one-to-one mapping with each parameter in the artificial bee colony; under the leading of the leader of each group, executing a parallel artificial bee colony algorithm to dynamically plan a path to move to the exit; and if the leader arriving the corresponding exit, waiting at the exit until the individual is inexistent in each group, and ending the crow evacuation simulation. Through the adoption of the method disclosed by the invention, the simulation efficiency and the channel efficiency in the public place are improved, and the assistance is offered for the real evacuation drill.

Description

technical field [0001] The invention belongs to the field of crowd evacuation calculation simulation, and in particular relates to a group evacuation simulation system and method combined with an artificial bee colony and a social force model. Background technique [0002] In recent years, with the rapid development of social economy, various large-scale public activities that gather a large number of people have been increasing, and the safety issues have attracted more and more attention. In some densely populated public buildings, due to unreasonable architectural design and inadequate emergency management, when various emergencies occur and people need to evacuate urgently, it is easy to cause crowding and obstruction of evacuated people , and even serious stampede accidents. It is of great significance to study the behavioral characteristics and movement rules of crowd evacuation under emergencies to promote the rational design of buildings and strengthen safety manage...
