Mooring maneuver evaluation system based on 3D virtual ships
In order to ensure the navigation safety in the process of ship driving and operation and accurately evaluate the practical operation skills of the crew,aiming at the problem of the lack of a complete evaluation index system for the evaluation of ship mooring operation,combining the safety evaluation of mooring operation conducted by the expert evaluation method and fuzzy comprehensive evaluation method,the membership function of each evaluation index was constructed.The analytic hierarchy process(AHP)was used to determine the suggested weight value and the standard value of each evaluation index to ensure the accuracy and reliability of the evaluation results.The three-dimensional virtual ship technology was used to develop a set of mooring maneuvering automatic evaluation systems according to the influence degree of each factor on mooring maneuvering,so as to realize the comprehensive evaluation of the ship's mooring operation.The study shows that the evaluation model has better accuracy,strong systematization,and easy to operate.The results of the system's assessment,when compared with the results of the expert assessment,showed a high degree of consistency,demonstrating the validity and reliability of the model in assessing the mooring skills of crew members.
