Research Of Configuration For Aiport Taxiway On Path Optimization

The increasing development of civil aviation transportation has caused serious congestion.Long ground taxing time has become an important factor,which constraint the efficiency of overall air transport network.Design a reasonable and efficiently taxiway configuration Planning is a great significant practical,which can ensur taxi safety,improve taxi efficiency and reduce ground delay.this practical can also increase civil aviation energy saving and emission reduction and improve passenger satisfaction.This paper focuses on the three aspects of taxiway configuration features of the taxiway,the configuration parameters of the taxiway and the configuration of the taxiway.it has make a scientific,systematic and in-depth research on theoretical research and practical operation.First,the type of the crossing point of the taxiway is introduced.The relationship between the running mode of the busy airport runway and the configuration of the skiing road is analyzed in detail.The correlation between the X cross points and the T cross points and the peak hour capacity is analyzed by SPSS software.It is confirmed that the number of two cross points is counted.The correlation between airport peak hour capacity is obvious,and the number of X crossing points can be regarded as the number of fast exit taxiway.Secondly,we choose the design parameters of taxiway configuration to determine the object of this study: the number and location of X intersection and the number and location of T intersection.The mathematical model of various parameters of the taxiway is set up.Taking the least occupancy time of the weighted runway as the goal,the method of dynamic programming is used to solve the position and quantity of the fast export taxiway.A numerical example shows that when the number of fast sliding settings is 2,the location is set at 1848 m and 2064 m,and the setting number is 3,and the location is set at 1780 m,2032m and 2293 m.Then we design the taxiway configuration scheme and establish the path optimization mathematical model based on the minimum total sliding time.The model is solved by combining genetic algorithm with sliding time window.Through the two schemes evaluation methods based on the delay cost and the fuel consumption measurement,the optimal solution of the example is plan 8 and the contact interval 253 m.Finally,the taxiway configuration is adjusted through the utilization factor of taxiway.
