Simulation And Optimization Of Flights Time Slot Of The Large Airports In China

With the rapid development of civil aviation in China,the number of flights at large airports in China is increasing,and the problem of flight delays is becoming more and more serious.It is an effective means to reduce the delay rate by means of flight time optimization.The current flight time optimization is mainly by setting up the mathematical model to set the constraints.But some large airports and airspace are more complex in the actual situation,the mathematical model is difficult to establish,the mathematical model optimization results are different from the actual situation,and the adjustment of flight time by simulation optimization can make up for this shortage.This paper mainly uses the simulation method to find out the machine.The bottleneck of a certain period of time in the field is to establish an optimization model for the bottleneck section,optimize the flight time,and improve the normal rate of Airport Flights.From the airport point of view,this paper finds the bottleneck of the airport through the simulation of the airport ground operation at the time of the flight plan,and adjusts the flight time for the design optimization model of the bottleneck link,simulates the optimized flight time again and optimizes the flight time by using the simulation results again,realizing the simulation and optimization.A set of corresponding flight time optimization system is developed for the fast interaction of simulation and optimization.Finally,taking Hangzhou Xiaoshan International Airport as an example,we optimize the simulated airport flight time,and verify the feasibility and effectiveness of the flight time optimization system.This paper first introduces the basic facilities system of the airport,including the taxiway system,the runway system and the downtime system,and introduces the operation rules of the airport.Secondly,it introduces the Anylogic simulation software,the advantages and disadvantages of the simulation software as well as some basic controls,functions,variables and simulation steps,and establishes the airport simulation model.The corresponding flight time optimization system is developed with VB language.The system is divided into four modules,flight time information module,airport basic information module,flight time optimization module and system information module.Each module can be subdivided into two modules,and the development steps of each module are also introduced.The function to be realized.Finally,the flight time simulation and optimization are carried out at Hangzhou Xiaoshan International Airport.Finally,the results of the simulation and optimization are finally obtained,and the feasibility of flight time optimization system and airport simulation is verified.
