Abstract

There have been many studies to analyze the ship collision risk of navigation. However, most papers mainly solve the navigation collision risk using DCPA (Distance to Closest Point Approach) and TCPA (Time to Closest Point Approach). There are limitations for being lack of considering the traffic weather conditions around the ships. In this paper, we propose a novel algorithm to solve the ship’s collision risk based on vulnerability, where DCPA, TCPA and bad weather environment are combined using fuzzy logic for e-Navigation. and its validity is shown with some experiments.
