Key node identification of container transport network based on muti-layer complex network theory

With the development of containerization of cargo, if the key nodes in the container transport network fail, it will inevitably have a serious impact on the entire container transport network. This paper proposes an improved information fusion algorithm to identify key nodes in container transportation network. Firstly, based on the structural characteristics of the container transportation network, this paper constructs a multi-layer network of container transportation. Secondly, a framework is proposed to measure the layer centrality of nodes in a single-layer transport network; Finally, the improved information fusion algorithm is used to obtain the global centrality of nodes; The results show that the top ten node cities identified in this paper are all port. cities, and the results are consistent with the actual situation.
