Description

Technical Field

[0001] The present invention belongs to the field of airport flight scheduling and information technology, and in particular relates to a flight reduction and time adjustment method and system based on an airport operation management committee model. Background Art

[0002] In recent years, the civil aviation industry has developed rapidly. The airport flight throughput has increased year by year, and the requirements for the airport flight coordination and scheduling capabilities have become increasingly higher. How to ensure that flight reductions can be carried out in a timely and orderly manner under complex and changeable flight adjustment situations to ensure the coordinated operation of airports is an issue that must be studied and paid attention to.

[0003] The Airport Operations Coordination Committee (AOC) is an organization responsible for airport operations coordination, aiming to improve the airport's operational efficiency and service quality. The AOC is jointly established by the airport, air traffic control and airlines to ensure safe, efficient and smooth flight operations by establishing information sharing channels and implementing air-ground release sequencing.

[0004] The airport's next-day flight information (flight number, departure time, departure time) will be planned in advance under normal circumstances, and the airport operation command center does not need to adjust it. However, when special circumstances occur (such as extreme weather, natural disasters, exercises, etc. that affect flight operations), the airport operation command center will select flights in a certain period of time according to the next-day flight plan and reduce or adjust them to other times.

[0005] The traditional method is basically manual adjustment by the staff of the airport operation command center. In the manual adjustment process, it is inevitable that there will be problems such as slow speed and inappropriate allocation time. In a Chinese patent (application publication number CN117764351 A, publication date 20231226), a method for automatic airport time adjustment is disclosed, which only describes flight time adjustment, while in actual scenarios, flight reduction, reduction and time adjustment flight screening, etc. need to be considered.

[0006] Through the above analysis, the problems and defects of the existing technology are as follows: the existing technology takes a long time to reduce and adjust the next day's flights, is inefficient, cannot meet the management needs of the airport transportation management committee, and cannot meet the needs of the airport's coordinated operation for safety, efficiency and smooth operation. Summary of the invention

[0007] In order to overcome the problems existing in the related art, the disclosed embodiment of the present invention provides a flight reduction and time adjustment method and system based on the airport transportation management committee model.

[0008] The technical solution is as follows: A flight reduction and time adjustment method based on the airport operation management committee model, including: S101, flight adjustment information acquisition, establishing flight operation adjustment information collection; S102: The authority shall, based on the flight operation adjustment intelligence collection, confirm the target collection of flights to be reduced for the next day; S103: After obtaining the flight reduction target for the next day, the airport operation command center will analyze the data of the airport, airlines and authorities, evaluate the affected flights for the next day and negotiate flight adjustment plans; S104: Each airline confirms the flight adjustment plan and forms a final flight reduction plan after reaching agreement with the airport and the authority.

[0009] In step S101, the flight operation adjustment information set includes flight operation adjustment information from airports, authorities, airlines, and major flight operation adjustment information; Among them, the main flight operation adjustment information includes: weather, emergency rescue, and information about flights being unable to enter or leave the airport due to a continuously low release rate.

[0010] In step S102, the next day's flight reduction target set is: [time period t, flight reduction ratio s].

[0011] In step S103, the affected next day flights are evaluated and the flight adjustment plan is negotiated, including: S1031, the airport calculates the number of flights to be reduced in each reduction period based on the next day's flight reduction target and the next day's flight plan data. ; S1032, count the number of flights of each airline in each period, and calculate the number of flights that need to be reduced by each airline in each period ; S1033, each airline company confirms the specific flight reduction set for each period , In order of airlines, is the time period sequence; S1034, adjust the reduced flights to subsequent time periods in sequence; S1035: If it is not possible to adjust the flight schedule during the remaining time period, the flight operation will be cancelled.

[0012] In step S1031, reduce the number of flights The calculation method is: ; In the formula, It is the serial number of the time period that needs to be reduced.

[0013] In step S1032, each airline needs to reduce the number of flights in each period. The calculation method is: ; At the same time, the following formula is satisfied: ; In the formula, For airlines during the period The number of flights planned.

[0014] In step S1034, the reduced flights are adjusted to subsequent time periods in sequence, including: (a) The number of flights in each hour does not exceed the capacity requirement ; (b) Scheduled flights are scheduled to arrive at a time period with spare capacity according to the principle of slot insertion; (c) If all eligible time slots have been filled and there are still flights that have not been adjusted, the remaining time slots cannot be reduced and the flights will be cancelled.

[0015] Another object of the present invention is to provide a flight reduction and time adjustment system based on the airport transportation management committee mode, the system implements the flight reduction and time adjustment method based on the airport transportation management committee mode, the system comprises: The flight operation adjustment information set establishment module is used to obtain flight adjustment information and establish the flight operation adjustment information set; The next day's flight reduction target set confirmation module, the authority confirms the next day's flight reduction target set based on the flight operation adjustment intelligence set; The flight adjustment plan evaluation module is used by the airport operation command center to analyze the data of the airport, airlines, and authorities after obtaining the flight reduction target for the next day, evaluate the affected flights for the next day, and negotiate flight adjustment plans; The final flight reduction plan acquisition module is used for each airline to confirm the flight adjustment plan and form the final flight reduction plan after reaching an agreement with the airport and the authority.

[0016] Furthermore, the system is mounted on a computer-readable storage medium, which stores a computer program. When the computer program is executed by a processor, it can realize the functions of the flight reduction and time adjustment system based on the airport operation management committee model.

[0017] Furthermore, the system is mounted on an information data processing terminal, which is used to provide a user input interface when executed on an electronic device to implement the functions of the flight reduction and time adjustment system based on the airport operation management committee model as described above.

[0018] In combination with all the above-mentioned technical solutions, the beneficial effects of the present invention are as follows: the present invention achieves rapid and effective reduction and adjustment of next-day flights by establishing a flight reduction and time adjustment method based on the airport transportation management committee model, thereby meeting the management needs of the airport transportation management committee and the goal of safe, efficient and smooth coordinated operation of the airport. The present invention can effectively enhance the airport flight coordination capabilities. On the one hand, by establishing multiple information channels for information sharing, flight adjustment information can be obtained in a timely manner; on the other hand, flight adjustments take into account both flight reduction and time adjustment, and can try to meet the maximum capacity conditions to ensure the airport flight throughput as much as possible.

[0019] The present invention can improve the coordination efficiency and operation efficiency of the airport, especially the operation and coordination efficiency in the case of large-scale flight reduction caused by extreme weather. In the traditional processing method, when flight reduction occurs, the airport needs to manually compile the flight reduction plan and communicate with the authority and each airline in turn, which is inefficient and easy to fall into the process of wrangling back and forth, and affect the subsequent flight arrangement and scheduling, which can easily lead to the efficiency of airport flight release, affect passenger travel, and increase the operating costs of airports and airlines. According to the technical solution of the present invention, on the one hand, flight operation information is shared, and relevant parties can obtain the latest situation in a timely manner; on the other hand, the flight reduction plan can be automatically and quickly generated, and the reduction is carried out according to the same proportion to ensure fairness, while also leaving room for airlines to adjust specific flights. Ensure flexibility so that all parties can reach an agreement as soon as possible. Leave enough time for all relevant parties to prepare for relevant reduction matters, such as corresponding flight plan updates, ground service scheduling, crew arrangements, etc. Try to ensure the airport release efficiency and operation performance. Ensure the normal travel of passengers and reduce the compensation costs of airlines. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0022] The innovation of the present invention lies in that the present invention can quickly formulate a flight reduction plan based on the flight plans of each airline according to the flight reduction targets given by the authority, and automatically confirm the flight reductions and flight time adjustments. The airport and the airline only need to make a simple confirmation, which improves work efficiency.

[0023] Embodiment 1, as Figure 1 As shown, the flight reduction and time adjustment method based on the airport transportation management committee mode provided by the embodiment of the present invention includes: S101, flight adjustment information acquisition, establishing flight operation adjustment information collection; Flight operation adjustment information comes from airports, authorities, airlines, etc. The main flight operation adjustment information includes: (1) Special circumstances include weather, emergency rescue, and a continuously low release rate; (2) Weather conditions may cause the efficiency of flight support to decrease during a certain period of time, resulting in the need to adjust a certain percentage of flights to other time periods. For example, according to the weather forecast, there will be thunderstorms between 8 and 9 a.m. the next day. Under such weather conditions, the efficiency of flight support is only 70% of the usual level. Therefore, the extra 30% need to be adjusted to the period after 9 a.m.

[0024] (3) The exercise will result in flights on a certain route or at a certain terminal being unable to enter or depart from the airport for a certain period of time; (4) Emergency rescue may result in flights at a certain terminal being unable to arrive or depart for a certain period of time; (5) The release rate is continuously too low due to other reasons, such as volcanic eruption causing route interruption in a certain area.

[0025] For example: the Civil Aviation Meteorological Center issues a notice that there will be heavy rain around the airport at 8-9 am and 12-13 pm the next day. Then these two pieces of information will form S1={(there will be heavy rain at the airport at 8-9 am the next day, which will affect flight operations), (there will be heavy rain at the airport at 12-13 pm the next day, which will affect flight operations)}.

[0026] S102: The authority shall, based on the flight operation adjustment intelligence collection, confirm the target collection of flights to be reduced for the next day; The next-day flight reduction target is mainly presented in the form of the next-day flight reduction target set [time period t, flight reduction ratio s].

[0027] For example, S2(1)[09-10,-15%] means that the number of flights between 9:00 and 10:00 the next day will be reduced by 15%.

[0028] The time period t is divided according to natural time, with each hour as a time period, such as: 0:00-1:00, 1:00-2:00…23:00-0:00 the next day, divided into 24 time periods.

[0029] Reduction of flight ratio: The authority will comprehensively consider factors such as the traffic conditions of air routes around the airport, airport runway parameters, number of parking spaces, etc., and give an appropriate reduction ratio. For example, due to weather conditions, the traffic efficiency of air routes around a certain airport is reduced (the number of flights passing per unit time is reduced) to ensure safety; the airport runway is slippery due to rain, so the number of flights released at the airport is reduced to ensure safety, etc.

[0030] S103: After obtaining the flight reduction target for the next day, the airport operation command center will analyze the data of the airport, airlines and authorities, evaluate the affected flights for the next day and negotiate flight adjustment plans; S1031, the airport calculates the number of flights to be reduced in each reduction period based on the next day's flight reduction target and the next day's flight plan data. ; ; In the formula, It is the serial number of the time period that needs to be reduced.

[0031] S1032, count the number of flights of each airline in each period, and calculate the number of flights that need to be reduced by each airline in each period ; Each airline needs to reduce the number of flights at each time period The calculation method is: ; Indicates that the airline is in the period The number of flights that need to be reduced = the number of flights planned for this period × the reduction ratio; At the same time, the following formula is satisfied: ; In the formula, For airlines during the period The number of planned flights is the number before the reduction. Corresponding to a specific flight list.

[0032] S1033, each airline company confirms the specific flight reduction set for each period , In order of airlines, is the time period sequence; Is a flight list Sort by historical flight regularity in ascending order and take the highest flights, i.e. For example, from Beijing to Shanghai, there are three flights from 6:00 to 7:00 on a certain airline: MU510X, MU515X, and MU516X. Their historical flight regularity rates are 89%, 87%, and 86%, respectively.

[0033] AL(6)={MU516 X (86%), MU515 X (87%), MU510 X (89%)}; Assume AC(6)=2, which means that two flights need to be cut during the 6-7 o'clock period.

[0034] AF(certain airline)(6)={MU5164(86%), MU5158(87%)}.

[0035] The airline will sort the flights during this period from low to high according to the historical flight regularity rate, and take the corresponding number of flights with the highest rankings.

[0036] According to the official documents of the Civil Aviation Administration, the flight regularity rate = (actual number of normal flights / total number of flights)*100%.

[0037] The historical flight regularity rate is calculated by taking the flight data of this flight in the past month.

[0038] S1034, adjust the reduced flights to subsequent time periods in sequence; When adjusting the time, the following principles should be followed: (a) The number of flights in each hour should not exceed the capacity requirement The airport has a capacity cap for incoming and outgoing flights in each hourly period; This is a number given after evaluation by a professional organization. For example, if the maximum number of flights released per hour at an airport is 15, , which means that no more than 15 flights can be released every hour.

[0039] (b) Flights that are scheduled to change their schedules will be scheduled to a time period with spare capacity according to the "slot principle". The adjustment time cannot exceed 4 hours and cannot exceed 6:00 the next day.

[0040] Slot principle: When flights are rescheduled, they will search for vacancies in the later time periods (i.e. if the capacity limit is not reached in the time period). If the upper limit is not reached, the flight can be rescheduled to this time period. If the upper limit is reached, continue to look for empty seats in the following hours.

[0041] When there is a gap, we try to ensure that flights are evenly distributed within this time period. Usually, one hour is divided into 6 small intervals of 10 minutes, that is, X:00, X:10, X:20...X:50. If there are many flights, they will be divided into 12 small intervals of 5 minutes.

[0042] If there are 15 flights in the next time period, the number distribution is usually: 00 minutes - 3 flights, 10 minutes - 3 flights, 20 minutes - 3 flights, 30 minutes - 2 flights, 40 minutes - 2 flights, 50 minutes - 2 flights.) (c) If all eligible time slots are filled and there are still flights that have not been rescheduled, the remaining time slots cannot be reduced for rescheduled flights and the flights will be cancelled.

[0043] When all eligible idle time slots have flights and the number of flights per hour reaches Due to the capacity limit requirements, there are still flights that have not completed the time adjustment, and the remaining flights can only be cancelled.

[0044] For example: there are 15 flights in the time period of 7:00-8:00, 13 flights in the time period of 8:00-9:00, and 12 flights in the time period of 9:00-10:00. Due to weather reasons, the number of flights in the time period of 7:00-8:00 is adjusted to 9, and 6 flights need to be reduced.

[0045] Assuming that the maximum flight release capacity per hour is 15 flights, the number of flights after 10 o'clock will reach the upper limit of 15.

[0046] Then there are 15-13=2 seats available in the 8:00-9:00 time period, and 15-12=3 seats available in the 9:00-10:00 time period. There are 0 seats available in the remaining time periods.

[0047] After 9:00, there are only 5 flights that can be rescheduled. There is still one flight that has no available time slot. The only option is to cancel.

[0048] S104: Each airline confirms the flight adjustment plan and forms a final flight reduction plan after reaching agreement with the airport and the authority.

[0049] Embodiment 2, as Figure 2 As shown, an embodiment of the present invention provides a flight reduction and time adjustment system based on an airport transportation management committee mode, including: A flight operation adjustment information set establishment module 1 is used for obtaining flight adjustment information and establishing a flight operation adjustment information set; Next day flight reduction target set confirmation module 2, the authority confirms the next day flight reduction target set based on the flight operation adjustment intelligence set; Flight adjustment plan evaluation module 3 is used by the airport operation command center to analyze the data of the airport, airlines and authorities after obtaining the flight reduction target for the next day, evaluate the affected flights for the next day and negotiate the flight adjustment plan; The final flight reduction plan acquisition module 4 is used for each airline to confirm the flight adjustment plan and form the final flight reduction plan after reaching an agreement with the airport and the authority.

[0050] The flight details are shown in Table 1: Table 1 Flight Details

[0051] like Figure 3 As shown, the airport capacity requirement is capped , that is, no more than 23 flights per hour; 1. Assume that the flight operation adjustment information set = {7:00-10:00 airport heavy rain warning}.

[0052] 2. The authority confirms that the target set of flight reductions = {(07:00-08:00, -20%), (09:00-10:00, -20%)}, which means that flights at 7-8 and 9-10 will be reduced by 20% each.

[0053] 3. Calculate the number of flights to be reduced in each hour period: C(7)=23*20%≈5, C(9)=20*20%=4. Count the number of flights of each airline in each period and calculate the number of flights to be reduced in each period; count and calculate according to the flight details table as shown in Table 2 and Table 3; Table 2, Flight schedule for 7-8 o'clock

[0054] Table 3: Flight schedule for the 9-10 o'clock time period

[0055] If there are very few airlines (such as 1 flight), and the reduction numbers of several airlines are consistent after calculation, you can refer to the historical normal rate data in S1033 and give priority to the airlines with normal flights.

[0056] Each airline confirms the reduction of flight schedule based on normal rate data.

[0057] AF(Australian Airlines)(7)={BK27XX (78.38%)} AF(Chengmu Airlines)(7)={EU18XX (79.41%)} AF(Huzhou Airlines)(7)={A672XX (81.52%)} AF(Southern Airlines)(7)={CZ37XX (80.33%)} AF(Xiamen Airlines)(7)={MF80XX(81.27%)} AF(Eastern Airlines)(9)={MU27XX (80.59%)} AF(Southern Airlines)(9)={CZ36XX (81.57%)} AF(Shandong Airlines)(9)={SC22XX (80.45%)} AF(First Air)(9)={JD56XX (78.98%)} Confirm that each airline has confirmed the specific flight reductions for each period After that, the reduced flights will be adjusted to the subsequent time periods in turn. The 7 o'clock time period will be adjusted to the 8 o'clock time period first, and the 9 o'clock time period will be adjusted to the 10 o'clock time period first. Flight adjustment must meet Flight restrictions.

[0058] Finally, the adjusted flight details are shown in Table 4; Table 4 Adjusted flight details

[0059] The distribution of flights in different time periods is as follows Figure 4 As shown, after inspection, the adjusted flight data meets the requirements and achieves the goal.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any modifications, equivalent substitutions and improvements made by any technician familiar with the technical field within the technical scope disclosed by the present invention and within the spirit and principles of the present invention should be covered within the protection scope of the present invention.
