Design And Implementation Of Flight Scheduling Simulation System

In recent years,the development of China's aviation industry still maintained a strong momentum.However,with the increase of flight traffic,the workload and difficulty of flight scheduling are increasing,and the congestion of busy airport is becoming more and more serious.At present,China's airport terminal area flight scheduling is still using manual scheduling,the controllers based on experience dispatch flights with randomness and uncertainty.It is easy to make airspace not fully utilized.Therefore,the airport terminal area automation scheduling research is of great significance.On the basis of the related research at home and abroad,this paper proposes a co-ant colony algorithm with A * algorithm for the problem of low efficiency of airport taxiway scheduling algorithm.Firstly,the result of the A* algorithm is used as ant colony heuristic information.Then the ant colony is used to sort the flight while detecting the conflict during the sorting process.And the collision resolution algorithm is used to deal with the flight according to the flight priority.Through the communication between the ant colony pheromone update iterative and ultimately,giving the optimal flight scheduling results.The experimental results show that the algorithm proposed in this paper has faster convergence speed and higher flight scheduling efficiency compared with the existing taxiway scheduling algorithm,and can provide decision support for taxi scheduling in busy airports.Aiming at the limitation of the existing taxiway scheduling model,this paper connects the flight landing problem and the taxiway scheduling problem through the shared resource of the runway.Combining the air network with the ground network,this paper unify the way to describe two issues.On the basis of taxiway scheduling,the collaborative scheduling that takes account of both landing and taxiing aircraft fusions the landing aircraft scheduling.At the same time,the collaborative ant colony algorithm is used to verify the cooperative scheduling model.The results show that the feasibility and superiority of the cooperative flight.Finally,the flight scheduling simulation system is designed on the basis of the above research work.The main functions of the system include the followings:1)The system can add flight scheduling algorithm through the updated version.2)By selecting the flight plan data and the airport network layout data,the system can obtain the optimal flight scheduling scheme according to the selected flight scheduling algorithm.3)The system can show the optimal value of each iteration of the algorithm and draw the change line graph.4)The system can show the optimal scheduling results.
