Dynamic scheduling method for multi-runway flight getting in and out

Abstract

The invention discloses a dynamic scheduling method for multi-runway flight getting in and out. The method comprises the following steps that flight delay cost is analyzed, and a flight delay cost minimization objective function for multi-runway flight getting in and out scheduling is provided; theoretic delay time is calculated, and flight delay time of different aircraft types is converted into delay time of unit delay cost; fairness of multi-runway scheduling is analyzed, and the objective function considering the fair factor is built; ordinary constrain conditions of multi-runway flight dynamic scheduling are provided; the multi-runway flight scheduling constrain conditions considering flight delay are designed; the dynamic scheduling problem of multi-runway flight getting in and out is solved by adopting the genetic algorithm, dynamic scheduling of multi-runway flight getting in and out is achieved, and the purposes of improving the runway using rate and reducing the flight delay cost are achieved. According to the method, influence on multi-runway scheduling caused by flight delay is sufficiently considered, and the purposes of improving the runway using rate and reducing the flight delay cost are achieved.

Description

Technical field: [0001] The invention relates to a dynamic scheduling method for the arrival and departure of multi-runway flights, belonging to the technical field of civil aviation. Background technique: [0002] The airport is one of the bottlenecks of civil aviation transportation, and the runway is the key resource of airport surface transportation. Reasonable scheduling of flight arrivals and departures can ensure flight safety, reduce delay losses and improve airline reputation. Therefore, scheduling the arrival and departure of multi-runway flights at large airports is one of the important contents of air transport management. [0003] The current scheduling of arrival and departure of multi-runway flights is mainly to establish a single-objective scheduling model with the goal of minimizing aircraft delay time or delay loss. dynamic scheduling and planning. Because large airports often have multiple runways, the complexity of flight arrival and departure scheduli...

AI Technical Summary

Problems solved by technology

Because large airports often have multiple runways, the complexity of flight arrival and departure scheduling is increased. The complexity is reflected in the fact that there are many take-offs and landings of flights. Once a flight delay occurs or a flight delay at other airports will cause a very large The impact of flight delays is large; second, flight delays, especially during flight-intensive time periods, will lead to the adjustment of multiple flight scheduling plans; third, the scheduling problems of multiple runways at hub airports are mutually Fourth, certain constraints jointly affect the scheduling of incoming and outgoing flights on the runway; fifth, flight delay is one of the key indicators for assessing airlines, and the scheduling of flight arrivals and departures on the runway is directly related to the interests of airlines
