Study on the Dynamical Model and Numerical Simulation Method of Field Spectator Violence

The evolution of field spectator violence is obtained by using the " dynamic" dynamical method and numerical simulation method.Our methods make up the " static" characterization of research on field spectator violence by speculative methods,statistical analysis and questionnaire investigation.Taking soccer as an example,for the cases with leaders and without leaders,we formulate dynamical models studying the evolution and the prediction of spectator violence,respectively.The result shows that the cohesion between the members of field spectators is not strong;there needs a long time for occurrence of field spectator violence in the case with leaders,but there will be huge destructive impact;the probability of the occurrence of field spectator violence will be greatly reduced with civilization watching the soccer game and when police and security personnel are present.According to our simulation results,we present the following advices for the prevention and control of field spectator violence:1)Field spectators should be educated and the number of police and security personnel should be arranged according to the numbers of field spectators and soccer hooligans;2)Different strategies should be taken by different types of spectator individuals when field spectator violence occurs;3)Emotion of soccer hooligans should be observed on time by establishing rogue file and quarantine measures should be taken when it is necessary and 4)the dialogue among the security personnel,the police and the stadium audience should be strengthened and the police's understanding of soccer culture should be deepened.The innovation of our proposed research methods and the corresponding results are important for the prevention and control of field spectator violence.In addition,they are also of important theoretical significance and have great potential applications.
