Problems solved by technology

[0003] At present, the research on container shipping network mainly focuses on analyzing the connectivity of the network from the perspective of the network characteristic index and network centrality of the shipping network by using the analysis method of complex network. The ranking of a single centrality index cannot accurately reflect the comprehensive status of nodes in complex shipping networks

Embodiment Construction

[0058] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0059] The invention proposes a method for evaluating the importance of ports in a container shipping network based on comprehensive centrality. Combining the ports and routes in the "21st Century Maritime Silk Road", a route network model is constructed based on complex network theory, and the topological properties of the network are analyzed. Based on the centrality theory of the network, the importance of ports is ranked. The specific steps are:

[0060] (1) Construct container shipping schedule database

[0061] The container shipping network is composed of route network and network nodes. ...

Abstract

The invention discloses a container shipping network port importance evaluation method based on integrated centrality, which comprises the following steps: S1, obtaining port route information in thecontainer transportation process, and constructing a container shipping network database according to the port route information; S2, constructing a container shipping network model; S3, calculating the average path length, the aggregation coefficient, the degree and the distribution function thereof, and further analyzing the network type of the contain shipping network model; S4, calculating thescores of degree centrality, approaching centrality and intermediary centrality of each port in the container shipping network model, and calculating the comprehensive centrality scores of each portby the comprehensive centrality method, and then ranking and evaluating the importance of each port in the container shipping network model. The invention provides an evaluation mode of port importance, carries out importance analysis and research on ports in a container shipping network, and provides a reference basis for investment construction of a marine port and optimization of a shipping network.

Description

technical field [0001] The invention relates to the field of evaluating the importance of sea ports, in particular to a method for evaluating the importance of ports in a container shipping network based on comprehensive centrality. Background technique [0002] Maritime transportation is an important way to improve a country's level of opening up and promote regional economic integration. Nowadays, many shipping groups have the functions and services of maritime logistics business. Ports and routes are an important part of maritime logistics business. The construction of ports will promote the optimization and improvement of existing sea and land transportation logistics channels. By studying the characteristics of container shipping network ports and the complexity of shipping networks, it can provide advice and reference for the construction of global ports and the optimization of shipping networks in the future. [0003] At present, the research on container shipping ne...
