Fuzzy Structured Element Method for Automatic Evaluation of Ship Maneuvering on Marine simulator

Marine simulator has been widely used in seafarer training and examination. Besides, in order to reduce the human subjective influence during the examination, the automatic evaluation system for ship maneuvering based on the marine simulator has become more and more necessary. So, the general design idea of the automatic evaluation system of ship maneuvering is proposed. And, considering different conditions when ship navigating in one channel, for example, poor visibility, narrow channel, and several modules for different conditions was designed to construct the whole system. Then, value sets of the trainees can be extracted from the simulator to compare with the expert sequence in the database. For illustrating the trainee’s performance comprehensively, the fuzzy structured element method was introduced into the evaluation. This method can not only describe the distance from the trainee’s operation to the experts’, also can comprehensively reflect the uncertain degree of each step during the trainee’s operation, which can provide more guidance for the trainee’s further development. Finally, actual example was taken to verify the model proposed. KeywordsAutomatic Evaluation, Fuzzy Structured Element Method, Marine Simulator, Ship Maneuvering
