A method and device for determining daily traffic capacity of an airport

Abstract

The invention provides a method and device for determining the daily traffic capacity of an airport. Wherein the method includes: obtaining a plurality of single-day flight plan quantities; using airport operation simulation software to simulate the operation of the airport under each of the single-day flight plan quantities, and obtaining the same number as each of the single-day flight plan quantities according to the simulation results Corresponding multiple airport busy degree evaluation indicators; using the set of the number of daily flight plans as the identification framework, using the multiple airport busy degree evaluation indicators as evidence, using DS evidence theory to determine one of the identified framework The number of flights planned for a single day is the maximum daily traffic capacity of the airport in question. Compared with the prior art, the present invention has the advantages of stronger comprehensiveness, better reflection of actual operation conditions, higher estimation accuracy, less calculation amount and higher efficiency.

Description

technical field [0001] The invention relates to the technical field of airport management and control, in particular to a method and device for determining daily traffic capacity of an airport. Background technique [0002] With the current increasing air traffic flow, flight delays occur from time to time. The determination of the airport's daily traffic capacity is of great significance to the reasonable mid- and long-term airspace planning and large-scale flow scheduling, and to minimizing delays at the system level. [0003] There are currently four main methods for determining airport capacity: based on spatial structure models, based on controller load calculations, based on historical data statistics and forecasts, and based on computer simulations. The first two types of methods establish mathematical models based on specific airspace structure characteristics, aircraft operating characteristics in the airspace, and controller control characteristics to calculate ai...

Problems solved by technology

The first two types of methods establish mathematical models based on the structural characteristics of specific airspace, the operating characteristics of aircraft in the airspace, and the control characteristics of controllers to calculate the airspace traffic capacity, which are more suitable for short-term specific situations and are not suitable for calculating the daily traffic capacity of airports.

The third method needs to be based on massive data, and the accuracy of the data needs to be guaranteed. The hardware requirements of the computing equipment required by it are relatively high, and the calculation time is also relatively long, which has considerable limitations from the perspective of realistic feasibility and cost. sex

Although this method is based on the maximum limit value of the operating rules, it does not analyze whether the corresponding operating conditions reflected by the simulation results really correspond to the maximum operating capacity level of the airport.

Therefore, the set maximum limit parameter value may make the obtained maximum daily capacity value too large or too small
