Research on Setting of Sector Opening and Closing Valve Based on Controller Workload

Abstract

Flexible open and close management of sector airspace is one of the main methods to improve the utilization of airspace.The full use of real-time airspace capacity and traffic flow information can provide early warning information for sector opening and closing,so as to improve the utilization of human resources and the ability to cope with the huge fluctuation of flight flow in emergency.Based on Wickens′information processing and cognitive model,the relationship between attention resources and control workload is constructed.Based on the susceptible infected recovered(SIR)model,the dynamic equations of attention resources and control workload are established.The stability of the equation at the equilibrium point is proved by Lyapunov stability theorem.Based on this algorithm,the opening and closing valve for sector operation is designed.Through numerical simulation,the evolution rules of attention resources and residual workload of controllers are verified.The sector opening and closing valve can provide sector opening warning for large flow and capacity environment and predict the future workload of controllers.
