With respect to extensive existence of subjective factors of multiple attribute decision making (MADM) in risk assessment of ships, this study applies intuitionistic linguistic variables to depict the information of decision making with multiple attributes, and combination coefficients are introduced to fuse the objective entropy weight and the subjective weight of various attributes. Fuzzy Euclidean Weighted Averaging (FEWA) operator is applied to calculate the integrated assessment values of ships in order to reflect the group opinions. With integrated linguistic assessment values and membership degrees as the basic measures of risk, the ship safety expectation is obtained. As for case studies, five ships undergoing insurance assessment are taken as the alternatives. Five ships are ranked based on their integrated assessment values and safety expectation values. It is found that intuitionistic linguistic variables are useful for efficiently evaluating risk levels of ships.
