Comprehensive Evaluation of Emergency Response for Super-Large Vessel Navigation in Port Areas Based on Cloud Modele

In order to better solve the problem of emergency response for super-large vessels navigating in the port area, this paper proposes an evaluation method based on the combined weighting cloud model. Firstly, the risk factors are analyzed and evaluation indicators are established based on three aspects: environment, vessels, and the development of emergencies. Secondly, AFP and entropy weight method are introduced and combined with cloud model theory and technology to construct an emergency response evaluation model for port navigation. Through case analysis, it is demonstrated that the model accurately assesses the risk of ultra-large ships when sailing in the port area, which providing a theoretical basis for ports and shipping enterprises to improve their emergency response capability.
