AGRASP-based algorithm called T_GRASP for avoiding typhoon route optimization is suggested to increase the security and effectiveness of ship *** of the worst natural calamities that can disrupt a ship’s navigation and result in numerous safety mishaps is a ***,the captains manually review the collected weather data and steer clear of typhoons using their navigational *** distribution of heavy winds andwaves produced by the typhoon also changes dynamically as a result of the surrounding large-scale air pressure distribution,which significantly enhances the challenge of the captain’s preparation for avoiding typhoon *** is now necessary to find a solution to the challenge of designing a highsafety and effective ship navigation path to avoid *** T_GRASP algorithm is suggested to optimize the candidate set’s structure based on the GRASP algorithm’s *** algorithm can guarantee the safety of the ship to avoid typhoons and assure high route efficiency by using the lowest risk function,the shortest sailing time,and the least fuel consumption as the objective functions and the ship speed and highest safety as the model *** outcomes of the simulation demonstrate the superiority of the suggested T_GRASP algorithm over both the conventional A∗algorithm and the ant colony *** addition to addressing issues with the traditional A∗algorithm,like its wide search space and poor efficiency,the proposed algorithm also addresses issues with the ant colony algorithm,like its excessive iterations and sluggish convergence.
