Abstract
Description
Technical Field
[0001] This application relates to the field of air transport management technology, and in particular to a method for assessing flight delay response levels and a central control device within a designated airport. Background Technology
[0002] With the rapid development of the air transport industry and the continuous growth of flight volume, large-scale flight delays caused by factors such as severe weather, airspace flow control, and emergencies are becoming increasingly frequent. As a key node in the air transport network, the operational efficiency of large hub airports directly affects the normal operation of the entire air transport network. Failure to provide timely and accurate early warnings and responses to large-scale flight delays will not only cause huge economic losses but may also lead to passenger congestion, service complaints, and seriously affect airport operational order and service quality.
[0003] Currently, domestic and international research on flight delay early warning mainly focuses on flight delay prediction, airport flight delay risk warning, and traffic congestion identification. However, research on the assessment of large-scale flight delay response levels at major hub airports is relatively limited. Existing flight delay response level assessments often do not consider airport operating time periods. Airports typically set fixed warning thresholds based on experience, lacking a scientific and dynamic assessment mechanism that cannot adapt to changes in delay trends at different times and under different operating environments. The traditional criteria for evaluating large-scale flight delays are subjective, relying mainly on daily experience and lacking time-specificity, failing to consider the characteristics of different airport operating periods. The determination of delay response levels is also relatively simple, lacking a systematic approach and a clear, operational method for determining criteria. Furthermore, there is a lack of a dynamic correction mechanism; once the criteria are established, they cannot be adjusted and updated according to changes in actual conditions. Unreasonable criteria can lead to inaccurate delay response level assessments, resulting in untimely delay handling or unnecessary occupation of handling resources.
[0004] Meanwhile, delay response level assessment is essentially a multi-indicator comprehensive assessment problem. Traditional matter-element models, when the measured data for one or more indicators of the matter being assessed are outside the segment interval, may fail to obtain the correlation degree of the indicators or result in inconsistent representation scales of the correlation degree with different segment intervals after substituting the measured data into the proximity function. Furthermore, a defined boundary for the delay indicator judgment interval is beneficial for measuring and calculating the correlation degree and weight of delay indicators. Although there is a theoretical upper limit to the right boundary of the segment interval in actual production operations, due to the objective requirements of safe operation and the existence of large-scale flight delay handling mechanisms, it is impossible to allow delay indicators to approach this theoretical upper limit in actual operation. Therefore, the segment intervals in the matter-element model are often countable sets whose right boundaries cannot be completely determined. Traditional methods do not handle this situation well, often ignoring this lack of interval closure and forcibly giving a defined right boundary for the segment interval. This approach does not adequately adapt to the actual operational situation.
[0005] Therefore, there is an urgent need for an early warning technology solution that can combine airport time-slot characteristics, dynamically adjust judgment criteria, adapt to complex data scenarios, and incorporate future trend analysis to improve the scientificity and accuracy of decision-making in response to large-scale flight delays.

Figure 2 The basic logical process for issuing early warnings of large-scale flight delays at hub airports. Figure 3 This is a logic diagram of a flight delay response level assessment system according to this application. In this embodiment, the executing entity of the flight delay response level assessment method is the central control equipment within a designated airport, such as the central control equipment of Daxing Airport (i.e., the backend server) or any computing device running Daxing Airport data (e.g.,...). Figure 3 (e.g., China Airport Flight Management System (FOMS)). Figure 1 As shown, the method for assessing the flight delay response level includes:
[0076] S100, based on actual flight operation data and flight plan data from the central control system within the designated airport (i.e. Figure 2 (Based on airport operation data and related information), obtain the values of multiple delay characteristic evaluation indicators corresponding to actual operation data and planned data.
[0077] Specifically, actual flight operation data and flight plan data refer to: flight number, arrival / departure flight identifier, planned arrival / departure time, estimated arrival / departure time, actual arrival / departure time, and origin / destination station.
[0078] Based on the flight operation status within a specified time period centered on the current time in the central control system of the designated airport, obtain the corrected flight volume for correcting at least one indicator.
[0079] The value of at least one delay characteristic evaluation index related to flight volume is adjusted based on the adjusted flight volume.
[0080] For example, the actual flight operation data and flight plan data in this embodiment can be the operation data for the current 24 hours and the flight plan data for the next 24 hours.
[0081] correspond Figure 2 In this embodiment, the selection of indicators can be based on pre-given indicator information.
[0082] S200. Based on the response level range information of each delay feature evaluation index, the values of the delay feature evaluation index are processed using an improved matter-element model to obtain the correlation matrix between all delay feature evaluation indices and all response levels, and the weight sequence of all delay feature evaluation indices corresponding to each response level.
[0083] For example, the delay characteristic evaluation indicators in this embodiment can be five or seven. When there are five indicators in this embodiment, the actual operation data and flight plan data of night flights may not be included. When there are seven indicators, the actual operation data and flight plan data of night flights may be included. Thus, the method of this embodiment can solve the technical problem that it is difficult to disperse stranded passengers caused by flight delays or cancellations after the suspension of comprehensive transportation at night, which can easily lead to passenger conflicts.
[0084] For ease of expression, all delay characteristic evaluation indicators will be referred to simply as indicators.
[0085] The matter-element model can be an existing model. In this embodiment, in order to better associate it with the delay feature index and interval information, an improved matter-element model is adopted. For details, please refer to the description in Embodiment 4 below.
[0086] The criteria for determining the delay response level of each indicator are shown in Table 1 below. The determination intervals for each delay response level can be pre-defined or manually assigned when used for the first time. In subsequent uses, the pre-defined intervals can be dynamically corrected based on delay data from multiple airports.
[0087] S300. Based on the correlation matrix and weight sequence, obtain the assessment value of flight delay.
[0088] S400. Based on the assessment value of flight delay and the given assessment rules, obtain the assessment result of the flight delay response level.
[0089] Based on the flight delay response level assessment method in the above embodiments, this method takes into account the characteristics of nighttime flights and supporting public transportation at large hub airports, and considers the optimization effect of future operation trends on the current warning level, thereby improving the foresight of decision-making, ensuring the accuracy of the assessment results, and is applicable to different airports.

For each response level, the airport, airlines, and relevant support units should take corresponding measures to minimize the impact of flight delays on passengers. Based on airport support capabilities and past experience, the judgment ranges for each delay response level are shown in Table 1.
[0168] Table 1. Judgment Intervals for Each Delay Response Level
[0169]
[0170] Currently, the criteria for determining flight delay response levels mainly rely on daily experience, and the judgment criteria are highly subjective. The aforementioned delay characteristic evaluation index system takes into account the operational characteristics of large hub airports. The calculation rules for all delay characteristic evaluation indicators are different. By combining airport support capabilities and past support experience, delay response level standards are set to meet the needs of stable airport operation.
[0171] Example 3
[0172] To better understand the corrected flight volume in S100 of Embodiment 1, this embodiment, in conjunction with the accompanying drawings, explains the specific steps for correcting the value of at least one delay feature evaluation index associated with the flight volume among multiple delay feature evaluation indicators based on the corrected flight volume.
[0173] In some embodiments, based on the flight operation status within a specified time period centered on the current time in the central control system of a designated airport, the corrected flight quantity for correcting at least one indicator is obtained, including:
[0174] Based on the flight operation status, the departure capacity of flights departing in the next 30 minutes, the planned number of flights departing in the next 30 minutes, the actual departure time, the planned departure time, the estimated processing time for delayed flights, and the number of delayed flights, the following calculation rules are used to obtain the corrected flight volume.
[0175] Obtaining the corrected flight volume is based on the analysis of future trends to correct the current delay situation, ensuring that the assessment results are more scientific and reasonable. This application mainly uses the corrected flight volume as a correction parameter for the large-area flight delay characteristic evaluation index, to correct large-area flight delay characteristic evaluation index 1 and index 2.
[0176] The number of delayed flights includes all scheduled but not yet departed flights as of the current time, which will need to be processed and executed later. A flight delay trend prediction chart based on corrected parameters is shown below. Figure 4As shown, with the middle horizontal line as the boundary, the upper half represents departures and the lower half represents arrivals. Using the current timeline (virtual vertical axis) as the boundary, the flight operation status is projected backwards and forwards within a certain time range, such as the planned and actual flight volume for the previous hour, and the planned and projected flight volume for the next hour. Figure 4 In the diagram, the number of delayed flights is the area difference between the planned departure flights and the actual departure flights shown on the line graph before the current time.

[0181] in: To correct for flight volume, NN represents the number of delayed flights, TT represents the estimated processing time for delayed flights, STD represents the scheduled departure time, and ATOT represents the actual departure time (null if empty). To ensure the departure capacity of flights in the next 30 minutes, This represents the planned number of departing flights in the next 30 minutes.
[0182] In this embodiment, based on future trends, the delay indicator parameters are adjusted using modified flight volume, enhancing the foresight of the assessment decision and ensuring a more scientific and reasonable assessment result. Compared to existing technologies, this approach optimizes the current early warning response level judgment by considering airport operating time periods and future flight delay trends. It improves the engineering applicability and situational awareness accuracy of large-scale flight delay response level assessment methods, enabling dynamic adjustments based on the current situation to adapt to changes in delay trends under different time periods and operating environments.
[0183] Example 4
[0184] In the implementation of this embodiment, the problem of flight delay response level assessment is reduced to a multi-index evaluation and analysis problem. In this embodiment, the basic model of traditional matter-element theory is used, and the improved correlation and weight calculation method of this application is applied to process the various indicators and the judgment intervals of each delay response level obtained in the aforementioned embodiment 2; the matter-element model corresponding to the seven indicators is used for illustration.
[0185] S201, based on the aforementioned seven indicators, construct the classical domain, the section domain, and the object element to be judged;
[0186] The classical domain is determined based on the characteristics of the matter-element being evaluated and its value range. Assuming the evaluation level is divided into m levels, then... To represent the j-th level, use Let represent the evaluation index for the i-th feature. In this embodiment, there are evaluation indices for 7 features. This represents the range of values for the i-th feature evaluation index at the j-th level. The range of values for this range is represented by the interval [interval name missing]. This indicates that a classical domain matter element is formed by combining N, c, and v in ordered triplet form. :
[0187] ;
[0188] definition Let the range of values for the domain element with respect to the i-th feature evaluation index be: ;
[0189] Among them, the range of values It is obtained by taking the union of all value intervals of the i-th feature evaluation index, that is... .
[0190] Then the domain element The expression is:
[0191] ;
[0192] The object to be evaluated is defined as:
[0193] ;
[0194] in, Let be the actual value of the evaluation index for the i-th feature of the object to be evaluated.
[0195] S202, Obtain the correlation matrix according to the following formula;
[0196] This formula expresses the correlation between the numerical values of delay characteristic evaluation indicators and the response level determination interval:
[0197] ;
[0198] in, For the elements of the classical domain matter-element model in the improved matter-element model, the actual value sequence of the matter-element to be evaluated. ; This represents the actual value of the i-th feature evaluation index in the object element to be evaluated; This represents the correlation value between the actual value of the i-th indicator in the object to be evaluated and the j-th delay response level determination interval. This represents the range of values for the i-th index in the j-th classical domain matter element. ; This represents the maximum value of the left endpoint of the value range of the i-th index in the classical domain matter element; This represents the minimum value of the left endpoint of the range of values for the i-th index in the classical domain matter element.
[0199] The correlation matrix is as follows: .
[0200] S203, obtain the weight sequence of each flight delay warning indicator corresponding to response level j according to the following formula. ;
[0201] This formula represents the weight of the correlation between the i-th delay characteristic evaluation index and different response levels:
[0202] ;
[0203] in:
[0204] ;
[0205] n represents the number of flight delay warning indicators;
[0206] This represents the maximum value of the left endpoint of the value range of the i-th index in the classical domain matter element;
[0207] This represents the left endpoint value of the value range of the i-th index in the domain element;
[0208] This represents the right endpoint value of the range of values for the i-th index in the domain element.
[0209] Based on the description of steps 201 to 203 above, in step S300, the assessment value of flight delay is obtained according to the correlation matrix and weight sequence, which can be specifically explained as follows:
[0210] The assessment value of flight delay is obtained using the following formula;
[0211] This formula is used to ultimately determine the degree of correlation between the object element to be evaluated and the response level: ;
[0212] in: This represents the overall correlation of the j-th delay response level; Represents the object element to be evaluated; This represents the correlation value between the i-th indicator and the j-th delay response level in the object to be evaluated.
[0213] Optionally, taking indicator 1 as an example, the method for determining the correlation between the actual value of a certain feature evaluation indicator and the interval for determining the delay response level is as follows: Figure 5 As shown:
[0214] Closed interval: The closer to the midpoint of the interval, the greater the correlation with the interval;
[0215] Non-closed intervals: The farther away from the left boundary of the interval, the greater the correlation with the interval;
[0216] In the table of judgment intervals for each delay response level, closed intervals are yellow and orange responses, and open intervals are red responses.
[0217] The judgment is based on the position of the indicator value relative to the entire range, to avoid the indicator being too large or abnormal trends being overweighted, which would lead to imbalance.
[0218] This embodiment addresses the bottlenecks in traditional assessment models, namely, the distortion of correlation and weight calculations after normalization due to differences in the dimensions of characteristic indicators, and the non-closure problem caused by the ambiguity of the right boundary of the judgment interval. It improves the traditional matter-element model and refines the calculation method of the comprehensive correlation between flight delay degree and various delay response levels. At the same time, it uses variable weight theory to construct an indicator weight calculation method, which improves the applicability of the assessment model and the accuracy of situational awareness.
[0219] To better understand the evaluation results in step S400 above, the evaluation results will be explained in detail below with reference to the weighting formula given above.
[0220] A certain object to be evaluated The comprehensive correlation matrix of its evaluation value as a flight delay can be:
[0221] ;
[0222] In practice That is, the final evaluation result, The corresponding value is the final assessment result of the flight delay response level. The highest value indicates that the current delay situation is in a state of widespread yellow response level. The highest value indicates that the current delay situation is in a state of widespread red response.
[0223] To further ensure accuracy and robustness of results, the method in this embodiment may further include updating the aforementioned manually given interval information.
[0224] For example, by updating the response level range information to which each delay feature evaluation indicator belongs, the criteria for judging the delay response level indicator can be optimized.
[0225] Specifically, historical operational data of designated airports (such as Daxing Airport) and historical operational data of other airports, as well as information on the frequency of flight delay warnings, are obtained. All data are statistically analyzed, and the probability distribution function of the duration of large-scale flight delay warnings at airports across the country is obtained.
[0226] In this embodiment, a probability distribution function and historical operational data can be used to dynamically fit the delay distribution pattern, and the flight delay response level judgment criteria can be statistically iterated and optimized to obtain the response level interval information of each delayed feature evaluation index, thereby reducing human influence.
[0227] The optimization approach and functional logic for the delay response level assessment criteria in this embodiment are as follows:
[0228] Data information including specific airports issuing delay warnings, the month of the warning, the duration of the warning, and the reason for the warning can be obtained from the Civil Aviation Administration's air traffic network. Taking large-scale flight delay warning data from all major airports in China over two years as an example, after comprehensive processing, the results show that the frequency distribution of the duration of large-scale flight delay warnings conforms to a log-normal distribution. Figure 6 As shown.
[0229] The probability distribution function of the duration of large-scale flight delay warnings at airports nationwide was obtained through fitting:
[0230] ;
[0231] in, It is the probability density function of the log-normal distribution model for a warning delay duration of t; These are the undetermined parameters for the log-normal distribution model.
[0232] Similarly, in this embodiment, historical operational data is used as data for review and analysis. Subsequently, the review and analysis data is periodically input into the delay response level assessment model to obtain early warning delay duration data. The statistical analysis output results are then fitted to obtain the corresponding probability distribution model parameters. The deviation value between the two parameters is defined as:
[0233] , ;
[0234] The above formula is used to continuously iterate and calculate until the deviation between the final fitted parameter result and the distribution parameter of the national historical delay data is within a given threshold range. Then the iteration optimization stops, thereby realizing the update of the judgment standard for delay response level index.
[0235] This embodiment dynamically fits the delay distribution pattern based on historical data and iteratively optimizes the judgment criteria, reducing human influence and significantly improving the scientific, accurate, and timely nature of large hub airports in dealing with large-scale flight delays. It has high practical value and promising prospects for promotion.
