英文摘要：

According to the types of work mistakes risk for air traffic controllers,the dynamic characteristic in construction process of index system were pointed out.From the aspects of personal,team,equipment,environment and management,the early-warning index system of work mistakes risk was established.Using the rough sets in advantages of data mining technology,through the attribute importance of heuristic reduction algorithm,the key index was extracted,and the redundant index was eliminated.Combining with the BP artificial neural network,the real-time warning model was built in the case of without the loss of critical early-warning monitoring object.It not only can help to speed up the computational speed,but also help to focus on the key object monitoring.Through the sample simulation,combining rough sets with BP networks,the early warning model was constructed,which could effectively realize the function of real-time warning monitoring for work errors risk of air traffic controller.
