Due to the complexity and vulnerability of Arctic waters, mass of security risks inevitably arise for ship navigation in the Arctic. In the perspective of security, an Arctic navigation security system with 4 levels and 24 evaluation indexes is developed in the present study. The fuzzy AHP based on trapezoidal fuzzy number is adopted, and expert weights are taken into account in the evaluation, so as to scientifically evaluate the weight of each index. According to the Pareto principle, the key factors are identified. The results of this study can provide reference for improving the arctic navigation security level.
