Abstract

In order to reduce risks in the approach control system and ensure the safety of the flight, firstly, based on the process method, risks in the approach control system were identified, and a corresponding risk control strategy was determined. Then, by constructing the extended risk control network chart of virtual risk nodes, the control problem of single risk factor was transformed into an integrated whole risk combination control problem. A risk control network model of the approach control system was built. The optimal combination scheme of risk control was determined. Finally, the model was applied to analyze a certain example. The results show that the system risk reduction value by the model is 19.30, and the required control cost is 227 000 Yuan, and that the model can be used to determine the optimal combination control scheme and reduce the risk level of the system. © 2019 China Safety Science Journal.
