Method of sector optimum partition based on controller workload

In order to ensure flight security and increase airspace capability, in according to the balance rule of controller workload, a simulated annealing algorithm was adopted to solve sector optimum partition, which was based on the statistic method of controller workload and the mathematical model describing airspace topology structure. The new resolution satisfied the restriction of the three rules for airspace partition, they were preferential search, sector continuity and the minimum of sector number. The optimum result of Xiamen control airspace shows that the maximal workload difference among three sectors is 4.1 s, the value is smaller than 17.5 s, which indicates that the method is feasible.
