In order to evaluate the safety status of transport ships, a multi-level fuzzy comprehensive evaluation model based on improved AHP (Analytic Hierarchy Process) is proposed. The weight of factors is determined by improved AHP, which effectively solves the problem that the judgment matrix determined by experts with strong subjectivity is difficult to be consistent, and the problem that a large number of single factor information of various risk sources is ignored is reasonably solved by using multi-level fuzzy comprehensive evaluation. This paper conducts the case study on the model. The results show that the model can evaluate the ship safety risk scientifically and reasonably, and provide reference for the ship management company and the maritime bureau to improve the management methods.
