Research On The Cooperative Development Mechanism Of Beijing-Tianjin-Hebei Air Cargo Based On SD Model

In the era of resource elements globalization and speed economy,the air cargo industry with high timeliness advantage has emerged rapidly in the transportation industry.More and more airlines are putting more capacity into the air cargo market,making air cargo a new national economic growth point.At present,Beijing-Tianjin-Hebei air cargo development is uneven,Beijing air cargo is in the forefront of the world,but the growth rate is gradually reduced by resource restrictions;Tianjin air cargo volume is not high;Hebei air cargo resources can not be used efficiently,regional imbalances And differential impacts have affected the orderly development of air transport.Based on the goal of maximizing the balance of air cargo between Beijing,Tianjin,and Hebei and the unified management of the regional airport group.The static analysis + dynamic simulation is used to coordinate the development and dynamic feedback mechanism between the regional air cargo system and the regional trade system.First of all,Meaning of coordination level and performance mode of regional logistics are defined,Then,from the perspective of economy and trade affecting the air cargo supply side,the establishment of regional air cargo coupling Coordinated indicator system,and evaluated the status of Beijing,Tianjin and Hebei;subsequently,based on the evaluation index system,found the relationship and feedback relationship between regional air cargo related factors,and established the Beijing-TianjinHebei air cargo coordination.The system dynamics model was simulated and simulated.Based on the simulation results,the regional air cargo coordination system was optimized and simulated,and the Beijing-Tianjin-Hebei air cargo synergy development plan was obtained.Finally,The aviation-based power feedback adjustment mechanism was designed according to the air freight power feedback adjustment mechanism.
