Navigation Risk Evaluation in Port Waters Based on Improvement Fuzzy Comprehensive Evaluation
Abstract— Ship navigation safety is affected by various factors. A ship navigation risk evaluation method
based on Rosen gradient projection method and fuzzy comprehensive evaluation is proposed in this paper. A
three-layer navigation factor fuzzy comprehensive evaluation model is established. Rosen gradient projection
method is used to calculate the weight of the model. This method can greatly weaken the influence of human
subjective factors, maintain a certain calculation accuracy, and make the evaluation objective and accurate.
Finally, experiments verify the feasibility of this method.
Index Terms— Gradient projection, fuzzy comprehensive evaluation, risk evaluation
