Evaluation on Northern Sea Route Navigation Environment

Northern Sea Route is known as a new route with complex navigation environment. It will greatly shorten the distance between the Far East and Europe. This article systematically analyzes the sailing conditions of Northern Sea Route and the main factors that influence the navigation environment. An evaluation index system is established. According to the fuzzy and gray characteristics of the evaluation index, the grey-cloud clustering model is built up and an actual evaluation is conducted. The results can not only enrich the relevance theory of polar research, but also provide reference for our country to make relevant strategic decisions on Northern Sea Route.
