Research On Personnel Evacuation Based On Game Theory

Public venues are highly crowded places.In the event of an emergency,it is very easy for people to be crowded and trampled,causing injuries and deaths,and endangering the safety of people’s lives and property.In the evacuation process,the escaper’s behavior strategies are often different,which is the main reason that affects the evacuation efficiency.It is particularly important to describe the behavioral conflict and strategy evolution of the escaper in the evacuation process.Game theory is that This is a good way to resolve conflicts and make strategic choices.Therefore,this article focuses on using game theory to study the conflicts caused by the behavior of survivors and the evolution of group behaviors driven by internal factors.First of all,the background significance of the evacuation and the serious consequences it may cause are investigated.The current research status and advantages and disadvantages of various existing models are introduced to explain the necessity of this study.At the same time,some individuals and individuals who escaped during the evacuation are described.Group behavior in order to simulate and reproduce these phenomena later.Secondly,this article combines the results of social psychology in the field of personnel evacuation,abstracts the two main behavior strategies in personnel evacuation,competition and cooperation,and then introduces game theory on the model of the dynamic ground field to describe the conflict caused by the two behaviors.In addition,the evolutionary game is used to simulate the evolution of the escapeee’s strategy to establish an individual decision-making model.Thirdly,a quantitatively described panic index and cost coefficient were introduced to study the impact on the evacuation process in different situations.The research found that:(1)The greater the panic,the lower the level of group cooperation,the more scramble behavior,and the evacuation efficiency.The lower.(2)When the cost coefficient is large,although the evacuation time becomes longer,it is conducive to the emergence of cooperative behavior.(3)The cooperative behavior of the survivors may be solely for self-interest rather than high quality.Finally,the causes of panic were analyzed,and the relationship between the degree of urgency and the index of panic was established to explore the impact of the inertia and rationality of the escapees on the evacuation process under different urgency levels.The study found that:(1)the state of affairs The higher the emergency level,the more unfavorable the cooperative behavior is and the longer the evacuation time.(2)In emergencies,excessive human rationality can cause social dilemmas,individual rational behaviors cause irrational group behaviors,and high intellectuals of people can inhibit group cooperation,which leads to an increase in evacuation time.It may be considered excessive.Reason is an important cause of group disasters.(3)The proportion of competitors and the evacuation time will increase first and then decrease with the increase of inertia,and the proportion of evacuation time and competitors will reach the maximum at medium inertia.This article uses Microsoft Visual Studio software to build a simulation platform based on game theory,to achieve the simulation of the behavior of the escaped in conflict,and draws some interesting conclusions.These conclusions also help to understand the inherent mechanism problems in the evacuation process,to a certain extent Reproduce and explain the situation of evacuation of people in real situations,and provide a scientific theoretical basis for the formulation of evacuation plans and venue design.
