A novel technique for predicting ship grounding based on fuzzy theory

Abstract

Due to the inefficiency of ship grounding prediction in Vessel Traffic Services (VTS), this paper proposes a two-stage alert architecture for this problem. Compared with conventional method which applies the uniform process to each object, the proposed method concentrates more on the individuation. The final calculation result-GRI (grounding risk index) can accurately reflect the degree of urgency that the ship to be grounded. The simulation results demonstrates that the GRI gives expression to the risk for grounding accurately in real time along one ship's track, shows that the method is effective and feasible. © 2011 Springer-Verlag Berlin Heidelberg.
