Analysis of Mass Violence Event Based on Analytic Hierarchy Process

This paper uses Analytic Hierarchy Process (AHP) to analyze the probability of individual appearing acts of violence by the influence of different roles in the crowd of Mass Violence Event, obtaining the weight of influence of organization leaders, agitators, general participants and bystanders to individuals. This paper also introduces spatial heterogeneity to reflect different roles' influence decaying with distance. By means of experiment, we obtain the approximate probabilistic data of individuals appearing violence in different locations and personnel situations, depict the roughly curve of probability affected by crowd density in different personnel situations. Then we can determine the areas of high violence probability in certain environment, which provide data support for the police to dispose analogous events.
