A Model Of Crowed Evacuation Simulation Based On Game Theory

In modern society, people gathered become normalcy. A large number of peoplegathered resulted in evacuation efficiency reduced when faced with an emergencysituation. In the self-organizing behavior and the role of external intervention,evacuation shows complexity.At present,computer simulation has become the main means of crowedevacuation. Domestic and foreign researchers study on the crowd evacuation modelwith variety dimensions: the body size, speed, density of personnel evacuationtime, walking space, human behavior etc. By the method of game theory to studythis problem is still in the initial stage. This article based on the Cellular Automatonframework,using Agent-based Model to simulate the independent existence ofindividual behavior and interactions between individuals. This model takes fullcharacterization of individual decision and behavior modeling. In the formulationof individual decision-making and conflict detection, this paper introduces the basicmethod of Game Theory.Other scholars emphasis on multi-exit evacuation model based on GameTheory,interesting in Nash equilibrium and evolutionary stable strategy in thestudy; or the emphasis with the evolutionary game theory strategy update research.The crowd evacuation in individual decision making and conflict checking processis actually a game between escapes. Different strategies to escape bring differentbenefits. This paper build a model to analysis and simulation that game.The simulation based on the Swarm simulation software, Swarm is Object-oriented features of good,clear hierarchy,with many convenient tools.Swarm developed for supporting agent-based model simulation. This paper widelyused the GUI interface to the simulation process visualization in the process ofsimulation. We can through the visualization model to verify the model’s rationality.The simulation result comparison with the related conclusion on evacuation of thesocial psychology support the research in social psychology found from the point ofview of model.This paper build a model based on the Cellular Automaton framework,usingAgent-Based Model by means of Game Theory. It described agent’s individualdecision and behavior in crowd evacuation, used Swarm simulation software toimplement and verify, obtained some social psychology theory of mutual supportconclusion. We can discuss more individual factors and complex environmentalfactors in next steps, we can also studies on the model of crowed evacuation multi-exit choice or evacuation of evolutionary game theory strategy update.At the sametime,we can correction model to describe the reality more rational and support thesocial psychology better.
