Research On Scheduling Of Ground Service Vehicles For Large Airport Airside Transition

Ground service for airside transition is the key work to ensure the normal operation of the aircraft.The efficiency and quality of airport services will be directly improved by the efficient use of ground service resources.At present,the ground service vehicle dispatching work at most airports in China is still in the stage of manual management.The work efficiency of this dispatching method is low,the quality of the dispatching plan is poor and it easily leads to flight delays.In order to ensure the normality of flights,improve the level of airport ground services and promote the intelligent development of large airports,it is necessary to rationally dispatch the ground service vehicles.A large hub airport in China is taken by this paper as a prototype to study the problem of ground service vehicle scheduling for airside transition and provides a better service vehicle scheduling solution for the airport.Firstly,based on the previous research results and the actual work of the airport,the work process,influencing factors and features of the ground service vehicles scheduling work for airport airside transition are analyzed,and the characteristics and solution methods of the vehicle routing problem are also discussed.Secondly,taking the ferry bus problem,which is the representative subject of the ground services operational process,as the research object,the assumptions related to the problem are determined,and various constraints such as the service flow of the vehicle,the configuration of the airport resources,and the time window of the ground service for airside transition are applied to the vehicle.The ferry bus dispatch model is established with the objectives of the minimization of the total vehicle number,the minimization of the total mileage of the vehicle,and the minimization of the difference in the workload between vehicles.Thirdly,based on the heuristic algorithm,a two-stage algorithm for solving the static scheduling problem is designed.A corresponding solution strategy is developed for dynamically updated flight information and the dynamic scheduling algorithm for the ferry bus is designed.Finally,the effectiveness and practicality of above theory is verified using the actual information of Kunming Changshui International Airport.The empirical results show that the static scheduling scheme can realize intelligent scheduling of airport ferry bus,effectively reduce the number of vehicles required and the total mileage of vehicles,improve the equilibrium degree of vehicle workload,and reduce the cost of ground services.At the same time,the use of dynamic scheduling algorithm can not only improve the efficiency of airport dispatching work and reduce the running cost of vehicles,but also obtain a vehicle routing plan in which the inheritance of adjacent dispatching schemes is high.Such a scheme is conducive to the redeployment of vehicle and driver tasks,and meets the needs of dynamic scheduling of airports.So the model and algorithm are suitable for solving practical problems.
