[0007] However, in these simulation models, the information mastered by people and the influence of people's subjective will on the evacuation process are ignored, and individuals are set to have perfect information and complete rationality, which deviates greatly from the reality

Embodiment Construction

[0015] (1) Application of cellular automata and multi-agent technology

[0016] (1) Cellular Automata

[0017] In the traditional cellular automata theory, multiple agents can be accommodated in a grid. When the number of agents exceeds a certain value, an agent is selected according to certain rules and moves randomly to the adjacent grid. When the agent is a person, this rule is often the priority, that is, the person with the worst mental state to leave. The premise is that the environment in which the cellular automaton is applied has characteristics—the agent can reach every place in the environment regardless of obstacles.

[0018] But the environment to be studied by the present invention must have internal obstacles, and the places with obstacles are just inaccessible. In addition, the collapse of buildings, fire or poisonous gas attacks will definitely affect the surrounding environment, and people's health and vision are not fixed. In this case, having multiple ce...

Abstract

The invention discloses a crowd-evacuation simulating method based on an extended BDI model. The crowd-evacuation simulating method, on the basis of the extended BDI model and with the cellular automaton and multi-agent technologies, can simulate the crowd evacuation in a public place in emergency (e.g. a fire, etc.) according to the plane layout of a building. The extended BDI structure provides a certain support for the factors in the spiritual aspect, so the method fully considers the influence of the psychological state of the people on the evacuation in the process of crowd simulation; the method is used for simulation of a crowd with incomplete environmental information; and the method can conform better to the practice. The method has an extensive application prospect in simulation studies of safe and fast evacuation of a large crown in a building and can test design proposals or responding proposals, and therefore the invention is an economical and feasible crowd-evacuation simulating method.

Description

technical field [0001] The invention relates to crowd simulation in computer graphics, in particular to a simulation model of personnel evacuation in a public place established based on an extended BDI model in an emergency (such as a fire) and its system realization. Background technique [0002] With the development of social economy and cities, large-scale buildings, such as skyscrapers, stadiums, stations, docks and airports, have emerged in large numbers. In these places, there are usually a large number of people coming in and out or staying. How to safely and quickly evacuate a large number of people in a building is not only a problem that must be carefully considered and studied when designing a building, but also an important research topic for emergency response plans for existing buildings. In this aspect of research, it is more economical and feasible to test the design scheme or response plan through computer simulation. [0003] Once an emergency occurs, whe...
