Complex Network Theory Model of Arctic Marine Rescue and Emergency Response

Global warming makes it possible for vessels to sail through the Northern Sea Route, and emergency rescue response to sudden and dangerous events at the Arctic Ocean has caused extensive concern. This paper analyzes the current situation of the Arctic marine rescue and uses complex network theory to describe the characteristics of Arctic marine rescue and emergency response networked system. A weighted complex network model is established and the empirical study is carried out. Through the calculation, the varying rescue response intensities of different countries were obtained. The cooperation of involved countries is needed to ensure the safety of navigation in the Arctic routes.
