Abstract: In order to evaluate the safety of ships in the Yellow River reservoir area, a multi-level comprehensive evaluation model using triangular fuzzy analytic hierarchy process was proposed. The triangular fuzzy analytic hierarchy process was used to determine the weights of factors, which effectively solved the problem that the subjectivity of expert scoring was strong and the judgment matrix was difficult to be consistent. The multi-level comprehensive evaluation was used to solve the problem of a large amount of single factor information submerged in a wide range of risk sources, and the model was studied with examples. The results show that the proposed model can assess the ship safety risk scientifically and reasonably, which provides a reference for the ship management company and the maritime bureau to improve the management method.
