Public security event scene representation method based on HyperGraph

A public security event scene representation method based on HyperGraph comprises the steps of building a public safety event scene evolution hypergraph, and decomposing the evolution hypergraph intotwo hypergraph models including an event-disaster-affected body hypergraph model and an event-disaster-pregnant environment hypergraph model; representing the hypergraph through a matrix to form an incidence matrix, and performing granulation analysis on the evolution hypergraph according to user requirements; and analyzing the topological characteristics of the public security event scene evolution hypergraph, and making risk evaluation. According to the invention, the public security event scene evolution network structure and the evolution relation are described from the perspective of interaction between the event scene and the scene elements, the public security event scene and the multivariate relation between the constituent elements of the public security event scene can be clearlydisplayed, the static sce
