Chance-constrained air traffic flow management method

Abstract

The invention discloses a chance-constrained air traffic flow management method. During a preliminary tactical stage of air traffic flow management, for an uncertainty of future capacity information,a chance-constrained method is used to preliminarily adjust a future air traffic flow; and the chance-constrained air traffic flow management method is specifically as follows: obtaining a flight schedule; obtaining sector capacity distribution information and determining a chance constraint value; and on the basis of the capacity distribution information and the chance constraint value, making apreliminary tactical air traffic flow management policy. The chance-constrained air traffic flow management method provided by the invention applies a chance constraint to the preliminary tactical stage of air traffic flow management, and preliminarily adjusts a flow according to future capacity distribution information under a condition where an airspace capacity is balanced with the flow at a large probability, to achieve the effect of greatly reducing total tardy of a flight; and the chance-constrained air traffic flow management method is easy to understand and easy to implement, only needs to predict airspace and airport capacities within a future period of time, and has advantages of promotion and practice.

Description

technical field [0001] The invention belongs to the technical field of air traffic flow management, and relates to a pre-tactical management method, in particular to a chance-constrained air traffic flow management method. Background technique [0002] The fundamental purpose of air traffic flow management is to balance the supply and demand of air traffic, to speed up and maintain the smooth flow of air traffic, and to promote the rational, effective and full utilization of airspace and airport resources. "Supply" refers to the capacity of airspace and airports, "demand" refers to the flow of flights, and the balance between supply and demand refers to ensuring that the flow does not exceed the capacity. The pre-tactical management method refers to the pre-allocation of traffic on the basis of the flight plan combined with the forecast information provided by the information network through ground waiting before takeoff, air waiting and diversion after takeoff. Because the...

AI Technical Summary

Problems solved by technology

Because the forecast information is not completely accurate, the future airspace and airport capacity are uncertain, making it difficult for relevant departments to make effective pre-tactical air traffic flow management strategies, so it is easy to cause more air congestion and flight delays
