Research On Scheduling Method Of Boarding Bridge In Large Airport

In recent years,with the rapid development of the domestic economy and the significant increase in the middle class population,the development of the air transport industry has advanced by leaps and bounds,and higher requirements have been placed on the service quality of the air transport industry,from the basic requirements of the previous safe arrival to the destination.With sufficient comfort and convenience,civil aviation transportation faces new challenges in terms of service and transportation quality.While the rapid development of civil aviation transportation industry has brought new challenges to the resource dispatching and flight support services of China’s airports,as the scale of domestic flights and the scale of routes increase year by year,the air traffic congestion is becoming more and more serious,and the number of delayed flights is rising rapidly..The rapid growth of flights at large airports poses a huge challenge to airport boarding bridge scheduling.How to improve the utilization of the boarding bridge,especially the near-board boarding bridge,while ensuring the safe operation of the boarding bridge equipment,with a certain number of available boarding bridges,to ensure airport stability and service guarantee efficiency and level Great significance.When the flight pre-scheduling scheme fails to meet the time requirement after the flight is delayed for some reason,the boarding bridge needs to be re-scheduled.The paper mainly studies the dynamic rescheduling phase of the boarding bridge.Specific work includes:In the large-scale airport research and analysis,the main reason for the need for dynamic re-scheduling is due to flight delays.Therefore,based on the actual situation of the airport,a number of flights and flights are scheduled to be dispatched to the far-end airport.The number of changes in the original correspondence of the boarding bridge,the time-weighting of the passenger arrival time and the minimum multi-target boarding bridge operation rescheduling model,and the constraints at the time of scheduling are set.There are many algorithms applied to solve the scheduling problem.An improved artificial bee colony algorithm is proposed to solve the model.The search process of the improved artificial bee colony algorithm is summarized and analyzed,including the introduction of greedy algorithm in the population initialization stage.Chaotic search and optimal solution strategies are added to the follow-bee local search and detection bee global search strategy.According to the actual flight information of a large airport in China and the distance time data provided by the airport,the three objectives proposed in this paper are analyzed and evaluated by Matlab.The experimental results verify the reliability of the model and the effectiveness of the algorithm.The proposed model can Better solution to the impact of flight delay on the rescheduling of the airport boarding bridge,compared with the previous rescheduling plan of the airport,improved the utilization rate of the near-camera.
