Research On Route Network Design Under The Operation Mode Of One City And Two Fields

With the continuous development of China’s civil aviation transportation industry,some aviation hub cities in China have begun to build urban second airports to meet relevant needs,and the concept of "one city,two fields" operation mode has gradually been proposed and discussed.In the new two-field operation mode,in order to achieve their own high-quality development,improve competitiveness,and rational route planning,the allocation of resources is particularly important.Therefore,it is necessary to conduct an in-depth study of the route network design of airlines.This thesis expounds the research status of the "one city,two airports" model and route planning and design at home and abroad,analyzes the typical two operating cities at home and abroad,discusses the route planning strategy of Airlines A in Chengdu under the "one city,two airports" mode based on the SWOT analysis method,and puts forward development strategy suggestions.Then,the comprehensive decision index system of route allocation is constructed and explained,the mapping and representation relationship of target layer,demand layer and decision layer is established,and 10 decision indicators are used to consider route allocation.Then,with the goal of maximizing airline revenue,a flight schedule evaluation model is established,and the optimization process of simulated plant growth algorithm is proposed to assist the screening of flight schedule in route network design.Finally,taking the route opened by Airline A in one city and two airports as an example,the experiment proves that the algorithm model can be closely related to the reality,and can solve the proposed problems in combination with the actual situation,so that the model is closer to reality and has strong versatility.Therefore,it provides a reference for airlines in the route network design under the "one city,two fields" operation mode,which is conducive to the next strategic planning and deployment of airlines and improves the competitiveness of airlines.
