The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Fig. 1 is a flowchart of a method for recommending a transit flight based on an aviation alliance and an airport main transit function according to an embodiment of the present invention. The method is suitable for the situation of carrying out optimal recommendation on flights transferred through the hub airport, and is executed by the electronic equipment. As shown in fig. 1, the method specifically includes:
S110, acquiring a plurality of hub airports, and extracting flight data of each hub airport in the same historical period.
As described in the background art, the terminal airport can ensure that most passengers can transfer in the terminal airport, and the number of transfer flights and the quality of transfer service provided by the terminal airport greatly influence the riding experience of the transfer flights. Therefore, in this embodiment, first, a plurality of hub airports and their historical flight data are acquired as the basis for airport evaluation and recommendation of the transfer flights.
In one embodiment, first, a historical period similar to a recommended period traffic environment is obtained. The recommended period refers to a period in which a transfer flight recommendation is required.
Then, a set of related data such as global flight data, airport location data, and annual airport passenger throughput ranking of a plurality of airports over the historical period is extracted. Optionally, the global flight data is from an OAG (Official Aviation Guide database ), each flight record including a flight number, an airline, a departure airport, a departure time, a departure date, an arrival airport, an arrival time, an arrival date, a flight distance, a weekly operation date, a number of seats, and the like.
Finally, selecting a plurality of airports with passenger traffic throughput arranged in the front as a plurality of hub airports to be evaluated.
S120, for the flight data of each hub airport, executing the operations of S1-S3 respectively:
S1, respectively combining each arrival flight and each departure flight in the flight data, and determining the maximum transfer time and the minimum transfer time of the two flights in each combination according to the types of the two flights in each combination and whether the two flights belong to the same aviation alliance, wherein the types of the flights comprise international flights and domestic flights.
The turn time refers to the length of time that a flight is turned from one trip to another. In general, the turning time includes a minimum turning time and a maximum turning time, where the minimum turning time can ensure that a passenger has enough time to transfer, and the maximum turning time can reduce uncertainty of waiting of the passenger. In this embodiment, the transit time is mainly affected by two factors, namely, the type of flight and whether two flights belong to the same aviation alliance. The transfer time required for an international flight is longer and the transfer time required for a domestic flight is relatively shorter in terms of flight type. In the case of the aviation alliance, if two flights belong to the same aviation alliance, seamless transfer service can be provided for passengers, and the transfer time required by the passengers is less; if the two flights do not belong to the same aviation alliance, more turn-around time is required by the passengers. It can be seen that, for the same flight, the present transfer combinations are different, and the transfer times may be different, so that this step first constructs a plurality of flight combinations, each including an arrival flight and a departure flight, and in the subsequent operation, it will be determined for each combination whether the arrival flight and the departure flight in the combination can complete transfer in the current hub airport.
In a specific embodiment, first, in order to improve the data processing efficiency, an arrival flight and a departure flight with a possibility of linking may be selected to be combined, instead of combining all the arrival flights and the departure flights one by one. Optionally, traversing each arrival flight and each departure flight in the flight data; if the actual arrival time of an arrival flight is earlier than the actual departure time of a departure flight, combining the arrival flight with the departure flight; if the actual arrival time of the arriving flight is later than or equal to the actual departure time of the departure flight, there is no possibility of engagement in time, and the method does not take into consideration.
And then, for each flight combination, respectively determining the maximum transfer time and the minimum transfer time of the two flights in the combination according to the types of the two flights in the combination and whether the two flights belong to the same aviation alliance. Alternatively, the process may include the following steps:
Step one, determining the same minimum transfer time for domestic flights in each combination, and increasing the outbound and inbound handling time based on the minimum transfer time to obtain the minimum transfer time of the international flights in each combination. Specifically, according to the meaning of the minimum turn time, the minimum turn time of the flight includes the time required for necessary links such as landing, taxiing, ferrying, re-check-in, etc. of the aircraft, the time is closely related to the type of the flight, and is not greatly related to which combination the flight belongs to, so that the same minimum turn time can be allocated to domestic flights in all combinations At/>Increasing the outbound and inbound transaction time as the minimum turn-around time/>, for all combined chinese interstar flights。
Step two, subdividing each combination into a first combination that two flights belong to the same aviation alliance and a second combination that two flights do not belong to the same aviation alliance. Through the first step, the minimum turning time of all flights in all combinations is determined, and the step continuously considers the influence of aviation alliance on the turning time to divide all aviation combinations into two types: one type is a combination in which two flights belong to the same aviation alliance, and is called a first combination; the other is a combination in which two flights do not belong to the same aviation alliance, referred to as a second combination. If the two flights do not belong to the same aviation alliance, the baggage is required to be extracted and the baggage is required to be re-checked during the transfer; and belongs to the same aviation alliance, the luggage does not need to be re-checked. The present embodiment will calculate the maximum turn time for each flight in the two classes of combinations accordingly.
And thirdly, increasing the maximum waiting time of passengers on the basis of the minimum transfer time of each flight in the first combination, and obtaining the maximum transfer time of each flight in the first combination. As described above, the first combination transfer does not require a re-check of baggage, and only takes into consideration psychological factors of waiting of the user. Specifically, if the flights in the first combination are domestic flights, then inIncreasing the maximum time that a passenger is willing to wait to get the maximum turn time/>, of the flight in the first combination; If the flights in the first combination are international flights, then at/>Increasing the maximum time that a passenger is willing to wait to get the maximum turn time/>, of the flight in the first combination。
And step four, increasing the time for consignment of baggage during the transfer based on the maximum transfer time of the first combination of flights of different types, and obtaining the maximum transfer time of flights of the same type in the second combination. As described above, the second combined turning machine needs to fetch and put the baggage again, and the maximum turning time is increased. Specifically, the maximum turn time of the first combined internal flight is known asIncreasing the time for consigning the baggage on the basis of the time, and obtaining the maximum transfer time/>, of the flights in the second combined China; The maximum turn-around time for the first combined chinese interstar is known as/>The time for consigning the baggage is increased on the basis of the time, and the maximum transfer time/>, of the second combined Chinese inter-flight is obtained。
The embodiment also provides a preferred implementation mode, and provides a numerical basis for determining the flight transfer time in each combination. Alternatively, for any one of the two flights in any combination, the minimum and maximum turn times may include the following four cases:
in case one, the flights are international flights and the two flights belong to the same aviation alliance, determining the minimum turn time of the flights in the combination 90 Minutes, maximum transfer time/>210 Minutes.
In the second case, if the flight is an international flight and the two flights do not belong to the same aviation alliance, determining the minimum turn time of the flights in the combination90 Minutes, maximum transfer time/>240 Minutes.
In the third case, if the flights are domestic flights and the two flights belong to the same aviation alliance, determining the minimum turn time of the flights in the combination60 Minutes, maximum transfer time/>150 Minutes.
Determining a minimum turn time of the flights in the combination if the flights are domestic flights and the two flights do not belong to the same aviation alliance60 Minutes, maximum transfer time/>180 Minutes.
S2, determining a plurality of time points in the history period, and judging whether each combination can finish turning in a time window taking each time point as a center according to the maximum turning time and the minimum turning time of two flights in each combination; if so, each combination is determined to be a transit flight.
In this embodiment, by means of the concept of the time window, it is determined whether each combination can complete the transfer at the current hub airport, and the basic theory is as follows: airlines generally centrally arrange inbound flights and outbound flights at hub airports, achieve basic synchronization of arrival and departure waves, promote effective connection of the inbound flights and the outbound flights, and further ensure compact connection of the transit flights. It is thus possible to achieve efficient turnovers and to form substantial communication between flights by continuously arriving and continuously departing flights within a certain time window. The present embodiment defines a time window based on the time center and the turn-around time. The moments of the time window are distributed axisymmetrically about the time center t c, as shown in fig. 2. Considering the time required by the passenger to transfer, assuming that the maximum transfer time of the international flight is I max and the minimum transfer time is I min; the maximum transit time of the domestic flight is D max, and the minimum transit time is D min. The definition of each moment in the time window is based on the following: the earliest international arrival flight of one shift is at the time t 1, and the transit flight can start at the time t 6 and can start at the time t 7 at the latest; symmetrically to t 1, t 8 is set. With t c as the center, the earliest arriving flight in the first class is at the time t 3, and the transfer flight can start at the time t 5 at the latest; with t c as the center, the latest arrival flight in the first class is at the time t 4, and the transfer flight can start at the time t 5 at the earliest. The time instants of the time windows are determined by the following mathematical equations:
since the turn-around times required for international flights and domestic flights are different, the arrival period and departure period of different flight types within a time window are different. From the definition of the time of day, the transit flights may include 4 types:
International arrival flights in the type one, t 1~t2 time window → turn → international departure flights in the t 7~t8 time window.
Domestic arrival flights in the time window of type two, t 3~t4, transfer, domestic departure flights in the time window of t 5~t6.
International arrival flights in time window of type three, t 1~t2, transfer, domestic departure flights in time window of t 6~t8.
Domestic arrival flights in the time window of type IV, t 1~t3, transfer, international departure flights in the time window of t 7~t8.
Thus, given I max、Imin、Dmax and D min, four types of transit flights can be combined by determining arrival flights within the time window t 1~t2、t3~t4、t1~t3 and departure flights within the time window t 6~t8、t5~t6、t7~t8, respectively.
Based on the above theory, the present embodiment determines a plurality of time centers with equal intervals in the history period, and for each time center, determines whether each flight combination can complete the transfer in the time window corresponding to the time center. As long as a combination is able to complete a transfer within a time window, it is added as a transfer flight (or referred to as a transfer-capable flight) to the transfer-capable dataset of the current hub airport. Unlike the basic theory described above, the turn time of the same flight in different combinations may be the same in this embodiment, and thus the time windows that the same flight needs to satisfy in different combinations may be the same, so it is not possible to directly determine which flights are included in each time window, and it is necessary to calculate the time windows that the two flights in each combination need to satisfy to complete the turn according to the types and turn times of the two flights in each combination, including the arrival time period of arriving flights and the departure time period of departing flights.
In one embodiment, the model is calculated based on equations (1) - (8) for each combination corresponding to a time window. According to the four types of transit flights, the calculation models are respectively as follows:
International arrival flights in the type one, t 1~t2 time window → turn → international departure flights in the t 7~t8 time window. If two flights belong to the same air consortium, the calculation model of the arrival period t 1~t2 of the arrival flight is:
The calculation model of the departure period t 7~t8 of the departure flight is:
If the two flights do not belong to the same air consortium, the calculation model of the arrival period t 1~t2 of the arrival flight is:
The calculation model of the departure period t 7~t8 of the departure flight is:
domestic arrival flights in the time window of type two, t 3~t4, transfer, domestic departure flights in the time window of t 5~t6. If two flights belong to the same air consortium, the calculation model of the arrival period t 3~t4 of the arrival flight is:
The calculation model of the departure period t 5~t6 of the departure flight is:
If the two flights do not belong to the same air consortium, the calculation model of the arrival period t 3~t4 of the arrival flight is:
The calculation model of the departure period t 5~t6 of the departure flight is:
International arrival flights in time window of type three, t 1~t2, transfer, domestic departure flights in time window of t 6~t8. If two flights belong to the same air consortium, the calculation model of the arrival period t 1~t2 of the arrival flight is:
the calculation model of the departure period t 6~t8 of the departure flight is:
If the two flights do not belong to the same air consortium, the calculation model of the arrival period t 1~t2 of the arrival flight is:
the calculation model of the departure period t 6~t8 of the departure flight is:
Domestic arrival flights within the time window of type four, t 1~t3 → turn → international departure flights of the time window of t 7~t8. If two flights belong to the same air consortium, the calculation model of the arrival period t 1~t3 of the arrival flight is:
The calculation model of the departure period t 7~t8 of the departure flight is:
if the two flights do not belong to the same air consortium, the calculation model of the arrival period t 1~t3 of the arrival flight is:
The calculation model of the departure period t 7~t8 of the departure flight is:
For each flight combination, according to the types of the two flights and whether the two flights belong to the same aviation alliance, a corresponding calculation model can be determined, the maximum turning time and the minimum turning time of the two flights are respectively substituted into the model, and the arrival time and the departure time which are required to be met when the combination finishes turning in the current time window can be respectively calculated. If the actual arrival time of the arrival flight in the combination falls in the arrival time period to be met and the actual departure time of the departure flight falls in the departure time period to be met, judging that the combination can finish turning in the time window, taking the combination as a transfer flight, and adding the transfer flight into a transfer data set of the current hub airport.
S3, accumulating the number of transfer flights to reflect the transfer capability of the hub airport; and identifying a main transfer function of the hub airport according to the transfer type of each transfer flight and the communicated region, wherein the main transfer function comprises an international transfer for communicating with three countries and an international transfer for communicating with a mother country and another country.
The method is characterized in that the number of the transfer flights in the hub airport and the main transfer function are identified based on the transfer flights in the transfer data set, and the number and the main transfer function are used as the basis of flight recommendation. In one embodiment, the number of flights in each airport is counted.
In addition, the main transfer function of the hub airport can be identified according to the transfer type of each transfer flight and the connected region. Optionally, among the four types of transit flights, type two belongs to a domestic transit, and the other three are all international transit. If the proportion of the domestic transfer machines in all transfer flights exceeds 60%, identifying the main transfer machine function born by the hub airport as the domestic transfer machine; and if the proportion of the international transfer machines in all the transfer flights exceeds 60 percent, identifying the main transfer machine function born by the hub airport as the international transfer machine.
Furthermore, when the main transfer function is the international transfer, the main transfer function of the hub airport can be further identified as the international transfer of the connected three countries or the international transfer of the connected mother country and other countries according to the airport and the city connected by the transfer flight of each international transfer. Wherein, the three countries refer to a mother country and two other countries.
S130, recommending a preferred hub airport and transfer flights passing through the preferred hub airport according to the number of transfer flights of each hub airport and the main transfer function.
The number of transit flights and the main transfer function of each hub airport can be obtained through the processing of each hub airport in S120, and based on the number of transit flights and the main transfer function, more optimal hub airports and transit flights transferred through the hub airports are recommended to passengers.
Alternatively, when the passenger opens the ticket booking software and has not entered the origin and destination, the passenger may be considered to have a travel intent, but the origin and destination have not yet been clarified. The passenger may then be recommended, on the software page, the top of the former hub airport and its associated flights, including the transit flights through these hub airports.
When the passenger inputs an explicit departure place and destination explicitly, the passenger may be simultaneously recommended a direct flight and a transit flight between the two places. When there are a plurality of available transfer flights, a hub airport with a larger number of transfer flights can be used as a transfer station, and the transfer flights with the main transfer function matched with the departure place and the destination of the hub airport can be recommended as the preferred flights.
In summary, the embodiment provides a method for recommending transfer flights based on the aviation alliance and the main transfer function of an airport, integrates the angle of the aviation alliance and the flight types, identifies the transfer-capable flight selection of the hub airport, is beneficial to evaluating the transfer capability and the transfer service quality of the hub airport more comprehensively and accurately, further identifies the transfer flight number and the main transfer function of the hub airport, and provides more reasonable advice for passengers to select transfer flights. Particularly, the influence of the aviation alliance on the transfer time is fully considered, the maximum transfer time, the minimum transfer time and the time window of each flight in each flight group are respectively calculated, the prediction precision of the transfer time is improved, and the identification of the transfer flights is more accurate. Meanwhile, the embodiment evaluates the transfer capability of the airport according to the number of transfer flights provided by the airport, and ensures transfer selection and experience of passengers. In addition, the international transfer function is further subdivided into two types of communication three countries and communication mother and other countries, the travel demands of passengers can be matched better, and accurate recommendation of transfer flights is achieved.
The acquired historical data includes data including global flights, airport location data, annual passenger throughput ranking, and the like. Wherein the global flight data originates from an official aviation data provider (OAG), each flight record comprising: flight number, airline, departure airport, departure time, departure date, arrival airport, arrival time, arrival date, flight distance, weekly operation date, number of seats, etc. Annual passenger throughput ranking comes from wikipedia. The passenger throughput with larger scale is one of important judging indexes of airport busyness and status, so the passenger throughput is used as one of key indexes for determining target hub airports, and the airport with global passenger throughput rank of top 30 in 2020 is selected as the hub airport to be evaluated.
The time centers were determined at 5min for one time interval, for a total of 288 time centers in a day. The maximum transfer time and the minimum transfer time of each flight in each combination adopt the values in the preferred embodiment, and the transfer flight number of 30 hub airports is calculated by adopting the method. The higher the number of transfer flights, the stronger the overall transfer capability of the hub airport and the higher the overall transfer quality. The results show that the airports with the top 5 transit flight numbers are mostly American airports, namely an American atlanta airport, an Chicago Aujel airport, a Dallas-Walsh airport, a Danver airport and a London Hirsquaro airport, the five airports provide more transit flight options, and the overall transit capacity of the airports is high.
The number of domestic transfer flights and the number of international transfer flights in the transfer flights of each major hub airport are further calculated, and the result is shown in fig. 3. The European airport, such as the International airport of London Hirslo, the International airport of Xiaer-dyke, the International airport of Amsterdam Shi Jipu and the International transfer rate of the Dibei airport of Asia, mainly bears the function of the International transfer machine in the global aviation network, and establishes a transnational connection; the airport in the united states can transfer and select more, but is mainly a domestic transfer machine, and the airport in the united states mainly bears the function of the domestic transfer machine in the global aviation network, namely, the airport in the united states mainly establishes connectivity for communication among all continents.
For the hub airport mainly bearing the international transfer function (in this embodiment, the airport with the international transfer rate of 15 ranking), the airport and city which are communicated with each other are identified, and are further divided into two types, namely, establishing aviation connectivity between three countries and establishing aviation connectivity between a mother country and other countries. The results show that: the five airports of debye airport, london greelo international airport, summer-dyke international airport, amsterdam Shi Jipu airport and frankfurter airport provide high proportion of the three countries that can be transferred, namely the function of establishing aviation connectivity among three different countries is mainly born in the global aviation network. In the choice of the transfer of four airports of Beijing capital airport, guangzhou white cloud airport, los Angeles International airport and Endi La Gan De International airport, the aviation connectivity of the mother country and the other country is high, namely the aviation connectivity of the mother country and the other country is mainly established.
According to the information, when the transfer flights are recommended, the hub airport with a large number of transfer flights can be selected, and the transfer flights with the main transfer function matched with the passenger travel region are used as the preferred flights.
