Reviwing research literature, factors which are effective on creation of maritime accidents has identified and classified based on view point of experts. Then, using Multi-Criteria Decision Making Techniques, including; AHP, SWARA, and Shanon Entropy, weight and importance of factors has determined. Finally, using Mean Ranking, Borda and Copland techniques, factors final ranking identified. Based on research findings, according to AHP technique, due to weight, factors importance are: human error, environment and route conditions, vessel technical conditions, profession planning conditions, physiological conditions respectively. Based on SWARA techniques, ranking of factors are: Human error, vessel technical conditions, environment and rout conditions, profession planning conditions and physiological conditions. Finally Shanon Entropy technique results show ranking of factors are: human error, vessel technical conditions, profession planning conditions and physiological conditions. At last, using Mean Ranking, Borda and Copland techniques final ranking of factors are: human error; vessel technical conditions; environment and route conditions; profession planning conditions; physiological conditions.
