Abstract

The invention provides a flight conflict resolution method and a flight conflict resolution device. The method comprises steps: according to a four-dimensional trajectory of a to-be-optimized aerocraft, a flight conflict situation estimation model is acquired, wherein each individual in the model comprises the departure delay time for all to-be-optimized aerocrafts, and different individuals are different; according to a target function, a target function value corresponding to the above model is acquired, wherein the target function is built according to the flight conflict situations between all to-be-optimized aerocrafts; all individuals in the above model are divided into M groups, and as for each group, a memetic algorithm is adopted for preset times of variation; the M groups are arranged in a cycle, the optimized individual in each group is copied to the next group sequentially to replace the poorest individual in the next group, an updated model and the corresponding target function value are acquired, and the model corresponding to the larger value in the two target function values is kept. The computing efficiency is high, the flight conflict resolution efficiency is improved, and the average departure delay time is low.

Description

technical field [0001] The invention relates to airspace traffic management technology, in particular to a flight conflict resolution method and equipment. Background technique [0002] In recent years, the air transport industry has developed rapidly, and it is expected that the civil aviation market will continue to maintain rapid growth in the next few years. However, as the flight traffic increases, the density of aircraft in the airspace also increases accordingly, making it difficult to guarantee the safe interval between aircraft, and the possibility of conflicts increases, which in turn poses a serious threat to flight safety. As one of the key technologies to ensure flight safety, research on flight conflict resolution methods is necessary and urgent. [0003] The research on the traditional flight conflict resolution method is mainly concentrated in the local airspace, lacking the global resolution method at the strategic level. In addition, the single-point calc...
