Research On Network Configuration And Port Resources Optimiza-tion Configuration Of The Yangtze River Container Transportation

Yangtze River container transport market continues to grow and develop,and it promotes the regional circulation of goods and watershed economic development,but in the process,there are many problems.Past researches for the Yangtze River container transport system are mainly about the ship and route,and port is mostly as a simple node to deal with,in fact,port nodes in the container transport system occupies a very important position.Based on the theory of complex system science,this paper analyzes the composition elements of Yangtze River container transportation system and its relationship,constructs the simulation model of Yangtze River container transportation system and carries on the simulation experiment,studies the performance of system performance under different configurations,and analyzes the optimal allocation of port resources under transportation system.The main achievements of this paper are as follows:(1)Element composition and network configuration of Yangtze River container transportation system.This paper analyzes the relationship between element composition and elements of Yangtze River container transport system from the perspective of system science,studies the influence of element activities on system performance,and puts forward three typical network configurations,including Wuhan and Chongqing as shipping center,a single star configuration for direct transport of each node,and a composite star configuration of the upstream node transit by Wuhan or Nanjing.(2)Construction of simulation model of Yangtze River container transportation system.Based on the basic activities of the container transportation system in the Yangtze River,the hierarchical model and the conceptual model of the system are established from the top to bottom.Then,the correspondence between the entity and the simulation element is established,and the system boundary and input parameters are determined.On the construction of the Yangtze River container transport system simulation model,put forward the logistics as the main line of macro-logistics system simulation modeling method.(3)Research on port node resource allocation for container transport.Based onthe analysis of the container port logistics activities of the container,the optimization of the resource allocation of the micro-node network under the environment of the macro-transportation network is put forward based on the system simulation method and the queuing theory.(4)The three network configuration of Yangtze River container transport system and port resource allocation simulation test research.The performance of the system is analyzed and the performance of the system is analyzed,and the resource allocation of the port under the single star configuration system is optimized.The research results of this paper have certain academic value to the simulation modeling of macroscopic logistics large system,which has certain reference value to the macroscopic understanding of deep container container transportation system,deep level quantitative analysis,policy formulation of future departments and future planning.
