Abstract: Ground operation is the basis of aviation security, and the prevention core is security check. Risk assessment of airport security system is important for aviation security. Seventeen risk factors of airport security system from four aspects(security personnel, equipment, environment and management) are identified, and the risk evaluation index system of the airport security system is built. Risk assessment model is established based on the gray analytic hierarchy process of airport security. The risk of an airport security system are evaluated as an example,and the calculated overall risk level is between normal risk and high risk. Research shows that the established model has good application value to the risk assessment of airport security system, providing basis for risk control.
