Multi-scenario Orientation Optimization For Gate Assignments

With the rapid development of logistics and transportation industry,the passenger throughput of civil aviation transportation airports is increasing,but at the same time,they are also facing some problems such as excessive airport load.Most of the airport ’s ground operations are carried out around aircraft that are parked in the parking space.The gate assignments directly affects the operating costs and efficiency of the airport and airlines,as well as passenger satisfaction.The effective gate assignments scheme is the key to the safety and efficient operation of airport.From the perspective of passengers and airports,this paper an overall study of the airport’s all-day flights is conducted.In the two states of single terminal and multi-terminal of airport,to make full use of the existing parking spaces and the best satisfaction of passenger,we consider the balance of parking space occupancy,and pay attention to the interaction of adjacent parking spaces in the gate assignment plan.The details are as follows:First of all,the development status of China’s civil aviation transportation industry is introduced in detail,the research status of the key means of airport seat allocation,as well as the differences of research at home and abroad.And the problems in the existing research are pointed out.Secondly,it analyzed the situation that the airport has only one passenger terminal,and discussed the distribution of the parking spaces under different types of passenger terminals.Then,based on the matching of flights and aircraft seats and the operational safety of the airport,the existing aircraft seats were fully utilized to analyze the service characteristics of the aircraft seats in each flight.The two-objective nonlinear programming model for the allocation of parking spaces under a single passenger terminal is solved using Lagrange.And the allocation of parking spaces under different types of passenger terminals,the results show that the model is suitable for the allocation of parking spaces under a single passenger terminal,which can enhance the anti-interference ability of the parking spaces and effectively improve the efficiency of airport operation management and passenger satisfaction.Thirdly,it analyzes the situation where the airport has multiple passenger terminals,and discusses the combination between the passenger terminals and the difference from a single passenger terminal.Then,based on the passenger’s route selection,the number of passengers on each flight,such as the number of seats in the flight room,was analyzed.With the goal of transit,the passengers had the least transfer tension and the most balanced idle time,the bi-objective nonlinear programming model for the gate assignment under multi-passenger terminal is constructed.It also solves the allocation of aircraft positions under different passenger terminal combinations and obtains the corresponding allocation plan.The results show that the model is suitable for the allocation of parking spaces in multiple passenger terminals,and can guarantee the execution rate of flight plans,so as to improve the service level for passengers and improve the efficiency of airport operation management.Finally,the main work and innovations of the full text are summarized,and the areas that need to be improved in the paper are given to point out the direction for future work.
