A Simulation Method of Regional Emergency Evacuation Process Based on Event Queue

Abstract

The invention relates to a region emergency evacuation process simulation method based on event queue. The region emergency evacuation process simulation method based on the event queue comprises the following steps: (1) obtaining region evacuation simulation initial element data and an evacuation transportation task list are obtained; (2) carrying out event lists, stimulation relationship between the events and each event processing procedure in a module according to evacuation transportation task list definition events; (3) sending initialized event information by an evacuation simulation system module, and adding timing sequence event queue; (4) inquiring timing sequence event queue by an event processing module, extracting the newest event in the timing sequence event queue to be carried out according to the relevant event processing procedure, and generating a new event according to the stimulation relationship between the events to add the timing sequence event queue, simultaneously, updating the element data in real time; (5) repeating the step (4) until the timing sequence event queue is empty; (6) recording each element final states by the evacuation simulation system, and finishing the evacuation simulation. Compared with the prior art, the region emergency evacuation process simulation method based on the event queue has the advantages of being fast in simulation speed, high in efficiency, and the like. The requirement of the evacuation of a large-scale passenger train can be met.

Description

technical field [0001] The invention relates to a computer simulation method, in particular to a simulation method of an event queue-based regional emergency evacuation process. Background technique [0002] With the development of society, the safety of large public places has attracted more and more attention. In these places, a large number of people come and go. Once an emergency occurs, how to safely and quickly evacuate a large number of people is not only a problem that must be carefully considered in architectural design, but also an important research method for the formulation of emergency response plans for existing buildings. In the actual environment, affected by cost and other reasons, the usual practice method is difficult to apply. The most economical and feasible method is to test the design scheme of the building and the emergency response plan through computer simulation. [0003] Emergency evacuation simulation is the basis for formulating regional emer...
