| In 2020,the new crown epidemic will spread around the world.The impact of the epidemic is intensifying the structural reshuffle of bilateral trade between countries,accelerating the promotion of the global value chain and the localization,regionalization and decentralization of the production chain.The global aviation consumer market has entered a period of deep adjustment.Air cargo It plays a huge role in stabilizing the global production chain and value chain.With China’s orderly resumption of work and production,the demand for domestic and international air cargo has surged.The state has issued incentives and measures to comprehensively improve the capacity of international air cargo and build an independent and controllable international air logistics.With the distribution index system,air cargo has bucked the trend and ushered in a major new opportunity for rapid development.As a comprehensive service base that can provide comprehensive and perfect logistics and distribution basic functions,the aviation logistics park will usher in rapid development.However,because the planning and construction of my country’s aviation logistics park functional area is still in its infancy,the relevant methodology and practical experience are relatively scarce,resulting in the lack of sufficient theoretical guidance and experience for reference in its spatial layout.In addition,the aviation logistics park functional area construction project has a long period,a large area,and a large investment.Once its layout planning is unreasonable,it will cause problems such as unclear functions,unsuitable scale,and messy layout.This is not only for the park The normal operation of the system causes adverse effects,and the cost and efficiency of changing the functional areas that are put into use are high.This paper selects the aviation logistics park of Beijing Daxing International Airport as the research target.The first step is to analyze the current situation and problems of the Daxing Airport Aviation Logistics Park,find the direction that can be optimized at the moment,and comprehensively consider the basic logistics functions,determine the layout optimization ideas,and get the specific 7 functional zones;then use the functional zone area calculation formula to solve the problem The size of the 7functional areas;finally,the correlation analysis of the functional areas of the Daxing Airport Aviation Logistics Park is carried out,including the logistics and non-logistics relations.The second step is to construct and solve the layout model of the functional area of the Daxing Airport Aviation Logistics Park.First,improve the traditional system layout method;then make preparations for modeling,including modeling assumptions and symbol descriptions;then set up objective functions and constraints;finally pass The particle swarm algorithm solves it to get the initial layout plan.The third step is to simulate and optimize the layout of the aviation logistics park of Daxing Airport.Through the observation during the simulation process and the detailed analysis of the data results obtained after the operation is completed,the deficiencies in the planning are obtained.Then,according to the spatial layout The problem is developed and improved,and the final optimization plan is obtained through debugging and operation. |
