Embodiment Construction

[0037] The present invention is used for solving the time slot optimal allocation scheme of the arrival and departure flights with multiple runs, and specifically comprises the following steps:

[0038] Step 1: Collect airport arrival and departure flight schedule information, and grasp airport capacity information;

[0039] Step 2: According to the airport capacity and flight time information, divide one of the time intervals into several consecutive sub-intervals, T={T 1 ,T 2 ,...,T N}, T is the time interval, T i It is the time subinterval i={1, 2, ..., N}, for example, the time interval between 11:00-12:00 in the morning is divided into 12 sub-intervals, T={[11:00-11:05], [11:05-11:10],...,[11:55-12:00]};

[0040] Step 3: Each interval corresponds to the airport capacity curve under a weather condition. According to the curve, the relationship between the airport’s arrival and departure capacity can be described as: Indicates the entry and exit capacity curves. A ...

Abstract

The invention relates to a multi-objective optimization method for collaborative allocation of time slots of multi-runway approaching-departing flights, belonging to the technical field of civil aviation. The multi-objective optimization method is mainly based on a collaborative decision-making idea and comprises the following steps of: firstly, dividing a time interval into a plurality of time slots, determining the approaching-departing capacity of an airport and dynamically creating time slots; secondly, establishing a multi-objective optimization model with minimum total delay cost, fair delay loss of each aviation company and balanced use frequency of each runway as objectives and with the effectiveness and the approaching-departing capacity of the airport as constraining conditions; and finally, solving by using a genetic algorithm to obtain an optimal flight time slot allocation scheme. The multi-objective optimization method disclosed by the invention is suitable for solving the time slot allocation problem of the approaching-departing flights of each airport.

Description

technical field [0001] The invention relates to a multi-objective optimization method for collaborative allocation of time slots for multi-runway arrival and departure flights, and belongs to the technical field of civil aviation. Background technique [0002] Flight delays are an important problem in my country's current air traffic. Delays not only bring huge economic losses and waste of resources, but also seriously restrict the development of my country's civil aviation industry. Especially in recent years, many large airports in my country have begun to build multiple runways to meet the needs of air traffic. The rationality of runway selection and time slot allocation will directly affect the economic benefits of each unit and the rational use of airport resources. Therefore, how to correctly select the runway and allocate time slots on the basis of safety, economy and benefit is the key to the current research problem. [0003] Coordinated ground holding is a commonl...
