Study On Optimal Refueling Strategy Of Flight Based On Linear Programming Model

The cost of aviation oil has long been an important factor affecting the operating cost of airlines.In recent years,the cost of aviation oil of large domestic aviation enterprises has been hovering between 25% and 40%.In addition,the long-term fluctuation of international crude oil prices,aviation oil costs also fluctuate,the large fluctuation of international oil prices has greatly hampered the performance of airlines,and even become a key factor for airlines to make profits.With the increasingly fierce competition between domestic and foreign airlines,how to reduce the cost of aviation oil has become a topic for companies to study.At present,although domestic airlines fuel efficiency(flight technology level)is much higher than the international level,the price of domestic airlines affected by the fluctuation of aviation fuel is higher than the average level in the industry.It shows that domestic airlines have poor ability to control aviation oil cost.On the other hand,with the increasing demand for international aviation,airlines have increased the proportion of international routes they operate.It is necessary to further enhance the sensitivity of airlines to the cost of international aviation oil.At present,domestic and foreign oil pricing strategies vary from country to country.Generally speaking,the oil supply market competition in countries and regions with more active market economy is more adequate.The price of aviation oil fluctuates almost with the market and is not disturbed by the government.The domestic aviation oil supply market belongs to the state monopoly industry,and the price is regulated by the state.The different pricing strategies of aviation oil in different countries and regions also lead to the different refueling prices of airlines at different points.For airlines,how to accurately estimate the fuel demand of each flight is the basis of aviation oil management.At present,major airlines have their own prediction models,and there are many mature software to automatically calculate and estimate the fuel volume according to the actual situation of flights.However,few models take the refueling price of landing airports into account,and make use of the difference of aviation fuel prices in different places to minimize the aviation fuel cost of flights.This study regards flight refueling decision as a multi-stage ordering strategy with price fluctuation.Through data analysis,the relationship between flight fuelconsumption and refueling volume is obtained.Then,a linear programming model with minimum cost is established to explore the optimal refueling strategy for airline flights.This study will test the results of the model calculation with the actual operation data of airlines in order to give more practical business guidance to the aviation enterprises.The aviation enterprises can formulate an order model with minimum cost based on the results of this study.
