Research on the Risks Evolution Model Based on Complex Networks in Airport Flight Area

Based on the complex networks model, a mathematical model and a topology model of risks evolution in airport flight area are constructed. The analyses of the mathematical model conclude clustering coefficient, average path length and degree distribution. The analyses of the topology model conclude in-degree, out-degree, node subnet number and the contained branched numbers. The control scheme of risks chain scission is proposed. The results show that safety management system vulnerabilities in airport flight area, lack of employee safety training, the ground staff security awareness and illegal operations and the lack of inclement weather are the crucial nodes of risks evolution model in airport flight area
