Robustness of maritime network along the Maritime Silk Road based on trajectory data

Abstract

Abstract Most of the current research on the robustness of the maritime network is based on container liners, ignoring the diversity of maritime trade. Based on the 2014 AIS trajectory data, this paper constructs the maritime network of three cargo ships of container, tanker and bulk along the MSR. The author uses two strategies of random attack and deliberate attack to analyze the changes of three networks under different attack strategies. The study finds: (1) The maritime network that is constructed based on the real cargo ship AIS trajectory more fully reflects the changes in the maritime trade route of the MSR. (2) The dry bulk maritime network is the most robust, the tanker maritime network is second, and the container maritime network is the most vulnerable. (3) In the deliberate attack, the container maritime network is extremely vulnerable, and the collapse domain of the tanker maritime network is short. Once the tanker network begins to collapse, it will quickly fail. The research results can provide decision-making basis for a comprehensive understanding of the MSR shipping trade, port investment planning, route optimization.
