Description

TECHNICAL FIELD

[0001] The application belongs to the field of civil aviation transportation, and particularly relates to an airline route operation mode selection analysis method based on fuel price changes. BACKGROUND

[0002] With the rapid economic development, the aviation transportation industry has developed rapidly. While the aviation transportation brings convenience to passengers, the problem of increased carbon emissions caused by the aviation transportation has begun to be concerned by people. According to statistics, 2% of the total amount of global human carbon dioxide (CO2) emissions is from aviation transportation emissions. Therefore, more and more countries aim at the carbon emissions of aviation transportation, establish a carbon emissions trading system, and use market mechanisms to more effectively allocate resources and control greenhouse gas emissions. The carbon emissions trading system allocates a certain amount of CO2 emissions to airlines. If the CO2 emissions of the airline exceed the permitted amount, additional emission fees need to be paid, which actually increases the aviation fuel price. The increase in aviation operating costs forces airlines to shift costs to passengers, resulting in reduced revenue and decreased service quality. In summary, according to the influence of fuel price changes on airlines operating a single route, a hub-and-spoke (HS) route network and a point-to-point (FC) route network, the airlines can select the route operation mode to maximize the total profit, and provide auxiliary support for the airlines to make decisions in advance.

[0107] The above and / or other aspects of the present application will become apparent and more readily appreciated from the following description, taken in conjunction with the accompanying drawings in which:

[0108] Figure 1 is a flow chart of the method of the present application. DETAILED DESCRIPTION

[0109] As shown in Figure 1 the present application provides a method for analyzing airline route operation mode selection based on fuel price changes,

[0110] Step 1, determining the total profit of an airline operating a single route, specifically comprising the following steps:

[0111] Step 1-1, determining the total cost of an airline operating a single route. The total cost of an airline operating a single route includes fuel cost and aircraft leasing cost, and the calculation method is:

[0112]

[0113] where g(e,s) represents the aircraft leasing cost per flight hour, expressed as The cost increases with the decrease of e, and when e is constant, g(e,s) per passenger decreases with the increase of s, r represents the unit fuel price, e represents the fuel consumption per seat per flight hour, s represents the number of seats, f represents the flight frequency, k represents the flight time, d represents the flight distance, and β and ε are cost parameters.

[0114] Step 1-2, determining the travel cost of passengers. Considering that there are two types of delays when passengers travel, frequency delay (the difference between the passenger's preferred departure time and the nearest flight time) and random delay (delay caused by not being able to board due to overbooking), the frequency delay cost depends on the airline flight frequency and can be represented as The random delay cost depends on the airline flight load factor and can be represented as λl. Therefore, the travel cost of passengers is calculated as:

[0115]

[0116] where p represents the flight ticket price, f represents the flight frequency, l represents the flight load factor, and γ and λ are demand parameters.

[0117] Step 1-3, determine the total number of passengers transported by each airline on a single route. Assume that the total number of passengers in the airline transportation market for this single route is 1, and the number of passengers served by the two airlines in the market is q1 and q2, respectively, and the ticket prices are p1 and p2, respectively. Although the ticket price will greatly affect the choice of passengers for airlines, brand loyalty will also affect the choice of passengers. For passengers who prefer airline 1, it is negative, and for passengers who prefer airline 2, it is positive. Assume that brand loyalty is uniformly distributed in the interval [-α, α], and the calculation method is:

[0118] The total number of passengers transported by airline 1 q1 is:

[0119]

[0120] The total number of passengers transported by airline 2 q2 is:

[0121]

[0122] Only when the ticket price p, flight frequency f and flight load rate l of the two airlines are the same, their passenger numbers are the same.

[0123] Step 1-4, determine the total profit of airlines operating a single route, and the calculation method is:

[0124] The total profit of airline 1 operating a single route π1 is:

[0125]

[0126] The total profit of airline 2 operating a single route π2 is:

[0127]

[0128] Step 2, based on the condition of profit maximization, analyze the influence of changes in aircraft fuel price on flight ticket price, fuel consumption, flight frequency, load rate and number of seats in a single route, which includes the following steps:

[0129] Step 2-1, in order to help airlines make decisions and choose appropriate flight ticket prices, fuel consumption, flight frequency and flight load rate to achieve maximum profit, it is necessary to determine the first-order partial derivative of the total profit function expression of airlines 1 and 2 operating a single route with respect to each variable, and the calculation method is:

[0130]

[0131]

[0132]

[0133]

[0134] wherein, denotes the first derivative of the total number of passengers q1 transported by airline A with respect to the flight ticket price p1;

[0135] Step 2-2, considering the symmetry of the above formula for airlines 1 and 2, after substitution and rearrangement, the functional expressions of flight ticket price, fuel consumption, flight frequency, flight load factor, and flight seat number can be obtained, and the calculation method is:

[0136]

[0137]

[0138]

[0139]

[0140]

[0141] Step 2-3, determine the maximum value of fuel consumption, flight ticket price, flight frequency, flight load factor, and flight seat number under the condition of profit maximization, and the calculation method is:

[0142]

[0143]

[0144]

[0145]

[0146] wherein,

[0147] When the market share of the two airlines is the same, i.e. then we get:

[0148]

[0149] Step 2-4, take the derivative of the above expression with respect to the unit fuel price to determine the change trend of fuel consumption, flight ticket price, flight frequency, flight load factor, and flight seat number with respect to the unit fuel price, and the calculation method is:

[0150] The change trend of fuel consumption with respect to the unit fuel price is as formula (21):

[0151]

[0152] This indicates that as the unit price of fuel increases, the fuel consumption of aircraft will decrease.

[0153] Because f * It's about e * Since the frequency of flights is a function of the price of fuel per unit, the trend of change in flight frequency relative to the unit price of fuel is the same as the trend of change in fuel consumption. That is, as the unit price of fuel increases, the frequency of flights will decrease.

[0154] The trend of flight load factor relative to unit fuel price is shown in equation (22):

[0155]

[0156] This indicates that as the unit fuel price increases, the passenger load factor of flights will increase.

[0157] Because p * It's about l * Since the function is , the trend of flight ticket prices relative to unit fuel prices is the same as the trend of flight load factor, that is, as unit fuel prices increase, flight ticket prices will increase.

[0158] The trend of the number of flight seats relative to the unit fuel price is shown in equation (23):

[0159]

[0160] This indicates that changes in unit fuel prices have no impact on the number of seats on a flight.

[0161] Step 3, based on the profit maximization condition, analyze the differences between the HS route network and the FC route network in terms of fuel consumption, flight frequency, and number of seats per flight. This includes the following steps:

[0162] Step 3-1: Since the above analysis only addresses the impact of fuel price changes on a single route, but actual air service is provided in a network environment, airlines can choose to operate either an HS (High-Speed) or FC (Fuel-Cost) route network. The following analysis is based on a three-node symmetrical city network layout, assuming all routes are equidistant and each city has the same market demand, and that this market is served by two airlines. Under the FC route network, each group of cities is connected by one route, while under the HS route network, only two routes connect two non-hub cities to a hub city. The total profit of an airline operating either the HS or FC route network is calculated as follows:

[0163] Total profit of airline 1 operating the FC route network for:

[0164]

[0165] Total profit of airline 1 operating HS route network is:

[0166]

[0167] Step 3-2, determine the values of flight ticket price p, fuel consumption e, flight frequency f, flight load factor l and flight seat number s of airline operating FC route network under the condition of profit maximization, the calculation method is: FC FC FC FC FC

[0168]

[0169]

[0170]

[0171]

[0172]

[0173] Step 3-3, determine the values of flight ticket price p, fuel consumption e, flight frequency f, flight load factor l and flight seat number s of airline operating HS route network under the condition of profit maximization, the calculation method is: HS HS HS HS HS

[0174]

[0175]

[0176]

[0177]

[0178]

[0179] Step 3-4, analyze the differences in fuel consumption, flight frequency and flight seat number under the operation of two different route networks, the calculation method is:

[0180] By comparing the following formula (36) and formula (37):

[0181]

[0182] ​​​​​​​​​​

[0183] The difference of aircraft fuel consumption between operating two different route networks is analyzed, because Therefore, operating HS route network can improve the fuel efficiency of the aircraft;

[0184] By comparing f FC and f HS , the difference of flight frequency between operating two different route networks is analyzed, because Therefore, the flight frequency under HS route network is higher than that under FC route network;

[0185] By comparing s FC and s HS , the difference of flight seat number between operating two different route networks is analyzed, because Therefore, larger aircraft can be selected when operating HS route network.

[0186] Step 4, determine the impact of aircraft fuel price change on the total profit of the airline operating HS route network or FC route network, specifically including the following steps:

[0187] Step 4-1, determine the difference of total profit of the airline operating two different route networks, the calculation method is:

[0188] The difference of total profit of Airline 1 operating two different route networks Δπ1 is:

[0189]

[0190] The difference of total profit of Airline 2 operating two different route networks Δπ2 is:

[0191]

[0192] Step 4-2, determine which route network the airline chooses to operate to obtain higher profit when the fuel price changes, the calculation method is:

[0193] Take the derivative of the total profit difference function expression with respect to the unit fuel price and rearrange it using symmetry to get equation (40):

[0194]

[0195] Let Substitute equation (41) into equation (42) to get equation (42):

[0196]

[0197]

[0198] Substitute equation (43) and equation (44) into equation (42) to get equation (45):

[0199]

[0200]

[0201]

[0202] wherein 0<θ<0.5.

[0203] By comparing the cost coefficient with the demand coefficient It can be determined that when the fuel price changes, the airline chooses to operate which route network to obtain higher profits.

[0204] Since when , θ<0.2025; when , θ>0.2025. That is, when θ<0.2025, the unit fuel price r rises more favorably to the operation of the HS route network, and vice versa. According to , when the cost coefficient is large enough relative to the demand coefficient , the unit fuel price r rises more favorably to the operation of the FC route network, thereby possibly deviating from the current HS route network structure.
