Aviation security check system on neural network risk assessment model

With the development of civil aviation,the problem of aviation security is focused by extensively in these years.Security checkt is the main part of aviation security,it is an important task how to enhance the management level further.So it is urgent to build up a reasonable risk assessment model to direct the security check management.In this paper,the characteristics of back propagation neural network and the steps to complete a BP model are discussed.The security check risk assessment model based on security check analysis was built up.,and a feasibility analysis of the model was checked according to an actual example.
