Description

Technical Field

[0001] The present invention belongs to the technical field of air traffic management, and in particular relates to a route airspace track collaborative planning method taking user preferences into consideration. Background Art

[0002] In recent years, with the continuous growth of air transport demand, the contradiction between air traffic demand and capacity has become increasingly prominent. In airspace with dense traffic flow, the current air traffic control operation mode and management methods of traditional flight plans combined with experience intervals are difficult to cope with the safer, more efficient and flexible air traffic operations in the future. To this end, ICAO has proposed operational concepts such as airspace organization and management based on information management, trajectory-based operations, and collaborative flow management, in order to improve the efficient operation of the air traffic network and improve the level of air traffic services, including adapting to the large flow, strong coupling, and high time-varying characteristics of future air traffic.

[0003] At present, most of the research on trajectory planning is to globally optimize all flight trajectories to be planned by constructing different multi-objective optimization models and trajectory adjustment strategies, and has achieved a certain degree of maturity in theoretical exploration, but these methods are still insufficient in terms of integration with the actual operation of air traffic control. During the actual operation of flights, airspace users are responsible for providing flight plan information, air navigation service agencies are responsible for airspace structure adjustment, and air traffic control units are responsible for flight scheduling within the jurisdiction of the airspace. This process requires the collaborative participation of multiple parties to better promote the efficient operation of flights. At present, the global trajectory optimization method has the problem of insufficient participation of all parties, resulting in low execution of the optimization plan. Therefore, it is urgent to build a route airspace trajectory collaborative planning method that has the ability to consider user preferences to achieve the goal of collaborative control of flight trajectories. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and to provide a method for collaborative planning of airway airspace trajectories taking into account user preferences.

[0012] Step S6: With the goal of minimizing system cost, all trajectory selection schemes and delay allocation schemes involving delayed flights are generated according to the flight delay states preferred by different airspace users and the set of alternative trajectories.

[0077] ,

[0078] The decision variables for ensuring that the flight is protected, the flight is delayed, the baseline delay is maintained, and the alternative trajectory is selected must comply with the 0-1 variable constraints.

[0079] In some embodiments, step S6: with the goal of minimizing system cost, generating trajectory selection schemes and delay allocation schemes for all delayed flights according to the flight delay status preferred by different airspace users and the set of alternative trajectories, including:

[0113] In summary, the route airspace trajectory collaborative planning method provided by the present invention can improve the deficiencies in the prior art. For complex route airspace capacity and flow balance problems, the present invention can assist air traffic control units to quickly realize conflict-free trajectory allocation of flights in the pre-tactical stage. In trajectory planning, it can consider the delay status preferences of different airspace users for delayed flights. In flight delay decision management, it can further consider the fuel cost, route charging cost and emission charging cost of the flight trajectory, improve the green sustainability of flight trajectories, and further provide technical support for the research and development of air traffic control automation systems and control decision support tools.

[0114] To further verify the effectiveness of the trajectory collaborative planning method provided by the embodiment of the present invention, the embodiment of the present invention selects the operating data of a typical day of the French national airspace system for simulation verification, including 6255 scheduled flights, 15 regional control centers, 1511 airspace configurations, 164 basic sectors, and 431 operating sectors. The time window for matching demand and capacity within the sector is set to 60 minutes (i.e., the operating sector updates the structure and capacity values ​​once an hour). The trajectories of airspace flights within 24 hours of the day are pre-planned, and calculations are performed according to the detailed steps of the claim specification to determine the latest four-dimensional trajectory of each flight plan.

[0115] like Figure 2 As shown in Figure 1, the initial flight demand of the operating sector is described. Considering that the airspace sector will allow additional overload operations in actual operations, it is assumed that the maximum allowable overload of the sector capacity is 50%. By comparing the demand and capacity values ​​of the operating sectors, 15 hotspot sectors that exist throughout the day are identified and used as experimental scenarios for this case. In these 15 hotspot areas, a total of 941 flights are affected, of which 427 flights are allowed to submit user preference information to improve the abnormal operation of their flights. Table 1 describes the basic hotspot information of a typical operating sector.

[0116] Table 1 shows the basic hotspot information of five typical operating sectors.

[0117]

[0118] Considering the differences in the operating costs of flights for each airspace user, we classify them into different cost scenarios. Table 2 lists the types of airspace users, the number of flights for each airspace user, and their associated costs and operating categories.

[0119] Table 2 User-related information participating in the user preference information submission process

[0120]

[0121] In order to illustrate the differences in flight schedule sorting between different models, we take the LFMMZL sector during 13:00-14:00 as an example to further describe the optimization results of the model. Table 3 provides the flight schedule list information for some benchmark delay scenarios and scenarios considering user preference. The relevant basic information mainly includes flight call signs, airspace users (AUs), estimated time of arrival (ETA), controlled time of arrival (CTA), delay preference status, optimization results, and the corresponding delay time difference.

[0122] Table 3 Examples of optimization results for the baseline delay scenario and the scenario considering delay preference

[0123]

[0124] like Figure 3 As shown in Figure 4, the decision results of airspace users who participate in user preference decision-making on flight delay status are described. As shown in Table 4, for the trajectory planning model considering user preferences, we can find a very good optimization result. Since airspace users are allowed to submit alternative trajectory options, the overall delay time of the case is significantly reduced to 135 minutes. At the same time, it can be seen from the table that most flights (i.e., 6083) maintain the original planned trajectory, accounting for 97% of the total number of flights. In other words, this means that only 3% of flights are allowed to deviate from the planned trajectory to reduce 99% of the overall delay, which is of great significance for the actual flight delay relief.

[0125] Table 4 Overall optimization comparison results of the baseline delay model and the model considering user preferences

[0126]

[0127] Through the above-mentioned specific implementation method and simulation verification, it can be illustrated that the method proposed in the present invention can take into account the delay status preferences of different airspace users for delayed flights in trajectory planning, and can further consider the fuel cost, route charging cost and emission charging cost of the flight trajectory in flight delay decision management, thereby improving the green sustainability of flight trajectories and providing technical support for the research and development of air traffic control automation systems and control decision support tools.
