Problems solved by technology

[0005] Overall, research on the impact of severe weather on airport flight operations has achieved certain results, but the models are mostly based on certain assumptions and are out of touch with actual flight operations
Most of the studies on the coupling relationship between severe weather and flight operations are not deep enough, and there are few studies on the performance changes of airport flight operations under the overall process of severe weather, and most of the existing studies use traditional statistical prediction methods, lacking in-depth combination of learning

Embodiment Construction

[0060] It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict.

[0061] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0062] 1 Airport flight operation resilience assessment model

[0063] 1.1 Construction of resilience assessment model

[0064] The present invention proposes an index that has memory and can comprehensively measure the actual operation performance of airport flights under bad weather, namely the departure rate (Departure Rate) is defined as follows:

[0065]

[0066] where: for [T 1 ,T 2 ] The total number of scheduled departures in the time period; represents the planned departure time at [T 1 ,T 2 ] The number of flights with a departure delay of less than 30 minutes at the same time within the time period; stands for T 1 delayed before ...

Abstract

The invention provides an airport flight operation toughness evaluation and prediction method in severe weather, and the method comprises the following steps: 1, constructing an airport flight operation toughness evaluation model, and evaluating the airport flight operation performance through different measurement indexes; and step 2, constructing an airport flight operation toughness prediction model based on LSTM, and predicting airport performance in severe weather. The airport flight operation toughness can be predicted according to meteorological factors, so that disasters are reduced, and the emergency response capability is improved.

Description

technical field [0001] The invention belongs to the field of aviation technology, and in particular relates to a toughness evaluation and prediction method for airport flight operation under bad weather. Background technique [0002] In recent years, the air transport industry has maintained a rapid growth trend, and the airport traffic has grown rapidly year by year. Due to the continuous update and iteration of software and hardware, the continuous improvement of aircraft performance, control technology, ground support and operating procedures, and the increasingly scientific scheduling of airlines, the impact of equipment reasons and human factors on the safety and efficiency of airport operations is constantly reducing. Bad weather has become the main factor restricting the normal flight of flights. In order to resist the severe impact of severe weather, the research on the resilience of airport flight operations is needed. [0003] Unlike the extensive literature on t...
