基于线性规划模型对航班最优加油策略的研究

Study on the Optimal Refueling Policies of Flight Based on Linear Programming Model

结合航油消耗的相关理论与实际数据,建立航班耗油量的预测模型,在此基础上考虑起落机场的航油差价,对单架飞机连续航段的加油成本进行建模,计算几个航段的最优加油量,从而得到最优加油策略,降低航油成本。结果表明,航班耗油量受航班加油量影响并呈线性相关关系。运用真实的航班运行数据进行模型验证,证明了优化后的加油算法可使燃油成本节约5%。

Studying on the theories of aircraft fuel consumption as well as the practical data,this paper develops a predictive model of aircraft fuel consumption.Furthermore,it considers the oil price difference among different airports,model the single aircraft fueling cost with multiple legs and obtain the optimal fueling policies.The results show that the fuel consumption of the aircraft is linearly related to the amount of fuel on the aircraft.By using the real operation data of the flights to verify our model,it proves that the optimal fueling policies can reduce the fuel cost by 5%.
