Safety Risk Evaluation of Air Traffic Management System Based on Combination Weights Method and Matter Element Model

Abstract

The safety risk situation of the air traffic management system directly affects the safe operation of air transportation. Comprehensively considering the safety operation characteristics of air traffic management system, the evaluation index system of safety risk is constructed. The combination weights of the air traffic control system evaluation index are determined by means of the Euclidean distance function. The matter-element analysis method is introduced to establish the matter-element model, and verified with instances. The results show that the matter-element analysis method can obtain the overall safety risk status of the air traffic management system, and obtain the safety risk status of each evaluation index, which is helpful to take effective measures to improve the safety risk management level of the air traffic management department.
