To improve the integrated evaluation on the operation performance of air traffic control,a general index system was established,including density of air traffic flow,safety performance,efficiency performance and workload of air traffic controller,and a classification evaluation method by means of artificial intelligence was presented on the basis of back propagation network model.Taking the Chengdu terminal area for example,under the condition of segregated operation on two parallel runways,a BP network model of 12-7-5 in topology was set up after 60 typical samples were collected for network training and test,and applied for classification evaluation for 40 exam samples.In comparison with another integrated evaluation method based on principal component analysis,both of the evaluation results were in agreement.
