Dynamic Sector Plan Based on Variable Precision Rough Set Theory

  • To precisely estimate sector number and improve the flexibility of sector plans,a dynamic sector plan method based on variable precision rough set theory was proposed. In the method,the rules for a sector plan of different flight numbers are derived from the existing flight data and based on the variable precision rough set theory,and constraints are sector capacities determined by the controller’s workload,and the number continuity between adjacent sectors. The method was applied to a practical case. The results indicate that the airspace sector number varies with the air traffic flow in different period of a day,and that the method is valid to achieve dynamic airspace sector plans.
