Abstract
The collective panic behavior, which is caused by PI (Propagation Intensity), influences the welfare of citizens and the stability of the society (business). A well-known challenge is to understand the spreading mechanism of the panic behavior. In this work, the PI is classified as and , defined in the coefficient (Promotion Intensity) and (Inhibition Intensity) in the probability. MAS (multi-agent-simulation) model/tool is used to construct the systematic structure composed of four types of the participants (the individuals, the mass media, the social leaders, and the supervisors).This tool stimulates the collective panic behavior from the initial coefficient and , showing the different results in the condition of the population size and the conformity. Through setting up the rules and the strategies in an emergency, the framework stimulates the interaction between the agents (e.g. between the individuals, between the individuals and the mass media, between the individuals and the social leaders, between the individuals and the supervisors). The results advocate that the current simulator might be an appropriate first step towards the simulation and analysis of the combination of rules and strategies in panic behavior.
Highlights
Nowadays, understanding the spreading mechanism of individual irrational behavior and the collective panic behaviors in an emergency is still an open challenge
The researches on the abnormal phenomena of panic behavior had been analyzed before this study(Chen et al, 2007; Dai et al, 2015; Kou et al, 2012).They can be classified among: (a) the ones, those proposed the practical cases for the panic behavior,(Thomas et al, 2002;Edward et al, 2005; Li et al, 2009), and (b) the ones, those analyzed the different facets of the theoretical models in mathematics(Bergemann et al, 1996; Barabasi et al, 1999; Kirman et al, 2001;Yuan et al, 2005; Izquierdo et al, 2005), and (c) the studies based on the model of the simulation in individuals(Du et al, 2011; Zhang et al, 2011; Liu et al, 2014; Zhang et al, 2014;Zheng et al, 2016; Carlos et al, 2016)
Referring to Coulomb's law, the degree of persistence of an individual's attitude toward collective panic behavior is analogous to the amount of charge in a vacuum neutral point charge, and the gap between individual attitudes is analogous to the distance between vacuum point charges, and the influence of individual attitudes is analogous to the interaction force between point charges, which reflects the change in attitudes towards panic behavior among individuals at the t and t +1moments
Summary
Nowadays, understanding the spreading mechanism of individual irrational behavior and the collective panic behaviors in an emergency is still an open challenge. It can be spread heavily in a positive or negative way. The current work presents an MAS tool, which aims at stimulating and analyzing the collective panic behavior in an emergency. The framework of the CPBsim (Collective Panic Behavior Simulation) is given. MAS model is constructed to explore the impact of the PI(Propagation Intensity). Last, it gives some discussions and conclusions.
