Mathematical Analysis of Air Traffic Control Safety Risk Coupling

The structure of air traffic control safety risk is very complex, which includes not only human factors, equipment element, environment element, management factors leading to the single factor risk, but also coupling risk after their forming, such as the single factor coupling risk, double factors coupled risk and more risk factors coupling. This paper illuminates the ATC risk flow, the connotation and classification of ATC risk coupling. It also discusses the adding process of the risk flow and heterogeneous homogeneous risk through the mathematical method to reveal ATC safety risk coupling law. In this way the paper can provide theoretical guidance and reference method for security departments to control risk with high efficiency.
