Research On Evolution Motion Of World Shipping Complex Network

World shipping network which is a typical complex network has obvious complexity. Within world shipping network, a large number of ports, ships, and routes are in the process of dynamic evolution. The study of world shipping network and its evolution motion can discover the nature of world shipping network, and can help us understand and accommodate world shipping network, which is the basis of making scientific relevant planning. Currently the research methods are still focused on the individual level. There are some useful results, but inevitably missing information on the overall level. The complex network theory can be used for real-world mathematical abstraction, describing the interactions between elements from the overall perspective.Therefore, using basic theory and methods of complex network, we consider the world shipping network as nodes in the network, and the shipping routes as edges, so the world shipping network will be visually abstracted into complex network. This paper focuses on the evolution and evolution motion of world shipping network. Firstly, based on research status, decide to use complex network theory and improved model; Secondly, define the concept of world shipping complex networks, then analyze the main features and evolution factors; Thirdly, with the principle of priority connections, build the world shipping complex network evolution model; Fourthly, according to the model, do the computer simulation, then analyze the simulation results and do further contradictions with several other models; Fifthly, according to the results of computer simulations, summarize the evolution mechanism. Through the study of evolution of world shipping complex network, we can understand the macro-link between various regions. The research provides theoretical basis for the analysis of transport, trade, economic links between various regions, provides theoretical references for equitable route distribution and improving network efficiency, and provides theoretical support for the national port planning and construction.
