Construction of airfield security risks evaluation index system based on the grey clustering

In order to do the scientific and reasonable comprehensive evaluation of airfield security risks and improve airfield security capabilities, this paper analysis the expert scoring results of airfield security risk assessment indicators based on the theory of gray clustering. And it constructes airfield security risks evaluation system. The system includes four aspects of risk, human fators, equipment and facilities factors, environmental factors and management factors. 20 second grade indexes are included in the system, including the matching degree of airport staff personality and positions, airport staff working pressure and so on. The construction of security risk assessment index system provides the guidance of airfield security risks investigation. It makes a contribution to the prevention of unsafe events occur and the security enforcement improvement.
