All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In this application, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
As can be seen from the background art, in order to guarantee the revenue of the airline company, the airline company needs to predict the booking value when the flight leaves the airport, and can use the predicted booking value to determine the market demand and then set up the corresponding selling price of the seat.
Therefore, the embodiment of the invention provides a flight booking value processing method and system based on an exponential model, which are used for determining a data acquisition point and departure time of a target flight and determining historical sample flights of which the departure time and the departure time of the target flight are in the same week dimension. The method comprises the steps of obtaining a first booking value of a designated cabin of a target flight corresponding to a data acquisition point, obtaining a second booking value of a designated cabin of a historical sample flight corresponding to the data acquisition point, and obtaining a third booking value of the designated cabin of the historical sample flight when the historical sample flight leaves. And determining whether the historical sample flights meet the use requirements based on the second order value, the third order value and the number of the historical sample flights. And if the historical sample flights meet the use requirements, predicting the departure reservation predicted value of the designated cabin of the target flight by combining a preset exponential model based on the first reservation value, the second reservation value, the third reservation value and the number of the historical sample flights. And calculating the standard deviation of the departure reservation predicted value based on the second reservation value, the third reservation value and the number of the historical sample flights. And according to the predicted value and the standard deviation of the departure booking seat obtained by calculation, the navigation department is subjected to income management and market trend prediction so as to ensure the income of the navigation department.
Referring to fig. 1, a flowchart of a processing method for flight booking value based on an exponential model according to an embodiment of the present invention is shown, where the processing method includes:
step S101: and determining the data acquisition point and departure time of the target flight.
It should be noted that each Data Collection Point (DCP) corresponds to a Data collection time, and each Data collection point indicates the number of departure days of a flight, that is, different Data collection points indicate the number of departure days of a flight, such as: DCP1 corresponds to a number of hong kong days (days away from hong kong) of 120 days, DCP2 corresponds to a number of hong kong days of 900 days, and DCP24 corresponds to a number of hong kong days of 0 days (in this case, DCP24 is also referred to as DCP-final).
It is understood that, in the process of predicting the departure reservation prediction value of the target flight at the departure time, the corresponding data needs to be utilized, and therefore, before performing step S101, flight data information corresponding to the target airline (the airline corresponding to the target flight) needs to be acquired.
It should be noted that the flight control system of the target airline company contains the flight data information of the index or increment of the driver (airline company), so that the flight data information corresponding to the driver can be acquired from the flight control system of the target airline company at predetermined time intervals (for example, at 24-hour intervals).
It should be further noted that, from the obtained flight data information, inventory data of a designated flight of the target airline company is obtained, where the inventory data includes inventory data of flights that have departed from the airport and inventory data of flights that have not departed from the airport, and the inventory data includes details of the flight space, the booking value of each space, the flight number, the origin airport, the arrival airport, the departure date (i.e., departure time) of the flight, and a week dimension corresponding to the departure date of the flight, and the week dimension indicates that the departure date of the flight is a day of the week.
It should be further noted that, in order to ensure the accuracy of the predicted departure reservation value of the designated space of the predicted target flight, it is necessary to ensure the richness of the obtained inventory data, so that when obtaining inventory data, a sufficiently rich amount of inventory data is obtained as much as possible, such as: taking the system date of the designated flight of the target airline company as a reference date, acquiring inventory data of departure flights three years (which can be calibrated) past the reference date, and acquiring inventory data of non-departure flights one year (which can be calibrated) in the future of the reference date.
In the process of implementing step S101, a data collection point of the target flight is determined, and the departure time of the target flight is determined.
Step S102: historical sample flights are determined whose departure time is the same week dimension as the departure time of the target flight.
As can be seen from the foregoing, inventory data of flights that have left and flights that have not left (including the target flight) is obtained, and at least week dimensions corresponding to the departure date and the departure date are included in the inventory data.
In the process of implementing step S102, from the departing flights, flights with the same week dimension of the departing time as that of the target flight are determined, and the determined flights are used as historical sample flights.
Such as: and if the departure time of the target flight is 12 months and 1 day in 2020, and 12 months and 1 day in 2020 is Tuesday, determining the flight with the departure time of Tuesday from the departure flights as the historical sample flight.
Step S103: and acquiring a first booking value of the appointed cabin of the target flight corresponding to the data acquisition point.
It will be appreciated that the above references that a data acquisition point corresponds to a data acquisition time, and thus for a flight, the data acquisition point may be used to obtain a corresponding order value from the inventory data for the flight, such as: the reservation value of the flight corresponding to DCP1 (120 days from port) is obtained.
In the process of implementing step S103 specifically, a first booking value of a designated slot of the target flight corresponding to the data collection point (DCPn) is obtained from the obtained inventory data of the target flight.
Step S104: and acquiring a second booking value of the appointed cabin of the historical sample flight corresponding to the data acquisition point, and acquiring a third booking value of the appointed cabin of the historical sample flight when the historical sample flight leaves.
In the process of implementing step S104, a second booking value of the designated slots of the historical sample flight corresponding to the data collection point (DCPn) is obtained from the inventory data of the acquired historical sample flight (departing flight), and a third booking value (i.e., departing booking value) of the designated slots of the historical sample flight when the historical sample flight departs from the airport is obtained.
Step S105: and determining whether the historical sample flights meet the use requirements based on the second order value, the third order value and the number of the historical sample flights.
It can be understood that before predicting the predicted departure reservation value of the target flight by using the data corresponding to the historical sample flight, it is required to determine whether the data corresponding to the historical sample flight meets the use requirement.
In the process of implementing step S105 specifically, a plurality of preset conditions are preset, it is determined whether the second booking value, the third booking value, and the number of historical sample flights satisfy all the preset conditions, and if all the preset conditions are satisfied, it is determined that the historical sample flights satisfy the use requirements.
The preset conditions are as follows:
and the second booking value and the third booking value are both more than or equal to 1.
The number of historical sample flights is greater than or equal to 4.
That is, for each historical sample flight, the second and third booking values for the historical sample flight need to be greater than or equal to 1. And the number of the historical sample flights is more than or equal to 4, so that the historical sample flights are ensured to cover the flights of the whole month, and the determined departure reservation predicted value is ensured to be more accurate.
And when the historical sample flight meets the conditions, predicting the departure reservation predicted value of the target flight by using the data corresponding to the historical sample flight. And when the historical sample flight does not meet the condition, the corresponding historical sample flight needs to be obtained again until the obtained historical sample flight meets the condition, and the following steps are continuously executed.
Step S106: and if the historical sample flights meet the use requirements, predicting the departure reservation predicted value of the designated cabin of the target flight by combining a preset exponential model based on the first reservation value, the second reservation value, the third reservation value and the number of the historical sample flights.
It should be noted that a corresponding exponential model (also referred to as an exponential regression model) is preset.
In the process of implementing step S106 specifically, if the historical sample flight meets the use requirement, the second booking value and the third booking value of the historical sample flight are used as sample data, and the departure booking prediction value of the designated cabin of the target flight is predicted by combining the first booking value of the target flight, the number of the historical sample flights and the exponential model, that is, the booking value of the designated cabin of the target flight is predicted when the target flight leaves.
It can be understood that, when the index model is used for predicting the departure reservation predicted value of the specified cabin of the target flight, the value of the first reservation value of the target flight does not need to be considered, that is, as long as the historical sample flight meets the use requirement, the index model can be used for predicting the departure reservation predicted value of the specified cabin of the target flight no matter how many the values of the first reservation value of the target flight are.
Step S107: and calculating the standard deviation of the departure reservation predicted value based on the second reservation value, the third reservation value and the number of the historical sample flights.
In the specific implementation of step S107, based on the second booking value, the third booking value and the number of historical sample flights, a standard deviation stdreror of the departure booking prediction value is calculated by using formula (1), and the standard deviation is used as an important basis in revenue management of the airline company.
In formula (1), Coefficient is a model Coefficient of the exponential model, Constant is a Constant of the exponential model, Bd is a third seat value of each historical sample flight, Bn is a second seat value of each historical sample flight, and Obse is the number of historical sample flights.
It is understood that the specific content of Coefficient is as formula (2), and the specific content of Constant is as formula (3).
In the above calculation of the standard deviation of the predicted departure reservation value, the calculation is performed using the parameters related to the exponential model, that is, the calculated standard deviation corresponds to the exponential model. Similarly, when determining the predicted departure seat value by using other types of models, the corresponding standard deviation can also be calculated by using the relevant parameters of the other types of models, that is, each type of model can calculate the standard deviation corresponding to the type of model.
In practical application, an optimal model can be selected from a plurality of models in the following modes: and selecting the optimal model from the multiple models by using a minimum standard deviation method according to the standard deviations corresponding to the multiple models.
It should be further noted that, when the index model is applied, the actual effect of the index model on predicting the predicted departure booking value of the designated cabin of the target flight can be determined by an F-test method.
In the embodiment of the invention, the data acquisition point and the departure time of the target flight are determined, and the historical sample flight with the departure time being in the same week dimension as the departure time of the target flight is determined. The method comprises the steps of obtaining a first booking value of a designated cabin of a target flight corresponding to a data acquisition point, obtaining a second booking value of a designated cabin of a historical sample flight corresponding to the data acquisition point, and obtaining a third booking value of the designated cabin of the historical sample flight when the historical sample flight leaves. And determining whether the historical sample flights meet the use requirements based on the second order value, the third order value and the number of the historical sample flights. And if the historical sample flight meets the use requirement, predicting the departure reservation predicted value of the designated cabin of the target flight by using the index model. And calculating the standard deviation of the departure reservation predicted value based on the second reservation value, the third reservation value and the number of the historical sample flights. And according to the calculated departure reservation predicted value and standard deviation, carrying out revenue management and market trend prediction on the navigation department, improving the accuracy of the predicted reservation value and ensuring the revenue of the navigation department.
In the above embodiment of the present invention, referring to fig. 2, the process of determining the predicted departure reservation value of the designated slot of the target flight in step S106 in fig. 1 shows a flowchart for determining the predicted departure reservation value according to an embodiment of the present invention, which includes the following steps:
step S201: and determining the model coefficient of the preset exponential model by using the second booking value, the third booking value and the number of the historical sample flights.
In the process of implementing step S201 specifically, the model Coefficient of the exponential model is determined by using the second order value, the third order value and the number of historical sample flights according to the above formula (2).
Step S202: and determining the constant of the exponential model by using the second order value, the third order value, the model coefficient and the number of the historical sample flights.
In the process of implementing step S202 specifically, the Constant of the exponential model is determined by the above formula (3) using the second order value, the third order value, the number of historical sample flights, and the model coefficient.
Step S203: and predicting to obtain the predicted departure booking value of the designated cabin of the target flight based on the first booking value, the model coefficient and the constant of the exponential model.
In the process of specifically implementing the step S203, the departure reservation predicted value Demand of the designated slot of the target flight is calculated and obtained through the formula (4) based on the first reservation value, the model coefficient of the exponential model and the constant of the exponential model.
Demand＝Constant+Coefficient*ln(Bf) (4)
In the formula (4), the Constant of the exponential model is shown in the above formula (3), the model Coefficient of the exponential model is shown in the above formula (2), and Bf is the first order value of the target flight.
