The assessment and analysis of the operational status and safety risks associated with Aids to navigation hold paramount significance in ensuring the safety of maritime navigation. This paper constructs a risk assessment system for Aids to navigation based on the AHP (Analytic Hierarchy Process) and entropy weight method. The evaluation system employs the AHP to subjectively weight both discrete and continuous data, while the entropy weight method is applied to objectively weight data that can be continuously monitored. The subjective and objective weights are combined with nonlinear weights to construct a risk assessment model. The model has been applied to analyze and evaluate the Aids to navigation data of the waters of Guangzhou Maritime Safety Bureau in 2023. The evaluation results show that the power risk of the aids to navigation is the main risk of the existing aids to navigation.
