In order to effectively prevent accidents caused by shipwreck, this paper proposes a fuzzy logic approach for navigation obstruction risk of shipwreck. Firstly, the historical accidents in the Yangtze River are analyzed to identify the influencing factors for navigation obstruction of shipwreck. These factors are classified into four categories, which are ship conditions, traffic environment, distance from the sensitive areas and natural environment. Secondly, after fuzzifying the influencing factors based on theoretical analysis and statistical data, a fuzzy rule base is established and the crisp values for navigation obstruction risk of shipwreck are obtained by defuzzification. Thirdly, the proposed approach is applied to the navigation obstruction risk assessment of several historical shipwrecks in Yangtze River. The assessment conclusions derived from the approach are consistent with historical evaluation experience, demonstrating the feasibility and practicality of the approach.
