Research On Design And Simulation Of Cargo Multimodal Transport Process In Jiaodong International Airport

Jiaodong International Airport is an important gateway airport in Northeast Asia.After its formal operation,it will make up for the backward infrastructure and insufficient capacity of Liuting International Airport.However,facing the increasing competitive pressure of regional airports,especially the significant influence of the siphon effect of Japanese and Korean airports,Jiaodong International Airport should seek innovative development.With the fragmentation of global trade and the rapid development of cross-border e-commerce,the advantages of organizing combined transportation among different modes of transportation can be reflected,which can overcome the limitations of a single mode of transportation,broaden the scope of transportation,and help improve logistics efficiency.Therefore,Jiaodong International Airport should reform the cargo transport mode,take cargo multimodal transport as the breakthrough point of the construction of the hub airport,fully integrate the advantageous resources of Qingdao’s aviation,railway and ocean transport,and construct the cargo multimodal transport process,which is of long-term significance to the integrated cargo construction of Qingdao’s sea,land and air.This thesis takes the cargo multimodal transport process of Jiaodong International Airport as the research subject.Firstly,it sorts out and summarizes relevant literature,defines the concept of air cargo multimodal transport,and lays a theoretical foundation for the research process of the paper.Then,it analyzed the current situation of multimodal transport in Qingdao and the air cargo business process of Jiaodong International Airport,and found problems such as low level of automation,irregular operation,unreasonable security check links,and imperfect information platform.Based on this,the paper constructs a preliminary domestic departure multimodal transport process,and analyzes and tests its performance through Petri net model.Secondly,the Flexsim software is used to model the process,the bottleneck of the process is found through simulation experiments,and the key elements of the process are improved and optimized by combining ECRS analysis method.By canceling the aviation security process,simplifying the information transmission process,and adjusting the operation capacity of key equipment and personnel,the process efficiency is increased by 22.82%.Finally,the paper gives the cargo multimodal transport process scheme of Qingdao Jiaodong International Airport,and puts forward the corresponding countermeasures and suggestions for the possible problems in the construction of cargo multimodal transport process of the airport.
