Method for evaluating positioning capability of intelligent ship dynamic positioning system

The invention provides a method for evaluating the positioning capability of an intelligent ship dynamic positioning system, and the method comprises the steps: calculating the maximum environment load which can be resisted by a target ship in each wind direction angle in a 360-degree range under each working condition, and the static balance relation between the maximum environment load and the thrust and thrust moment outputted by a corresponding thruster; drawing a dynamic positioning system capability analysis curve graph; determining a comprehensive weight of an evaluation index by obtaining a subjective weight and an objective weight of the evaluation index; and further obtaining a comprehensive evaluation value of each wind direction angle under each working condition, drawing the comprehensive evaluation value into a rose diagram, and comprehensively evaluating the positioning capability of the target ship under different working conditions. The invention is suitable for the characteristic that the in
