" Maritime piracy risk assessment and policy implications : A two-step approach "
Maritime piracy is a serious threat to the safety of cargo , ships , and crews , which can cause enormous losses to stakeholders , highlighting the significance of piracy risk assessment and prevention to the maritime industry . In this study , we propose a two-step analytical framework based on a Random Forest ( RF ) model , Generative Adversarial Nets ( GANs ), and Matrix Completion ( MC ) algorithms to assess the risks of successful piracy attacks . We consider different decision-makers in each step , namely , pirates first select which ships to attack and then ship operators determine the probability of a ( un ) successful attack . According to a proposal of the researchers , there are different influencing factors for each step and , in the meantime , are solving the problems of incomplete and imbalanced data . A case study in Southeast Asia is then conducted based on the proposed approach . The results show that , in mild wind weather , the likelihood of a piracy attack on a ship with a DWT not exceeding 50,000 tons is up to 90 %. Further , if the attack occurs between 0 and 6 a . m ., the probability of success is over 90 %. These results provide more specific information for ship operators and local authorities to develop efficient anti-piracy strategies and policies .
