三维虚拟船舶系泊操纵评估系统

Mooring maneuver evaluation system based on 3D virtual ships

为保障船舶驾驶操纵过程中的航行安全,准确评估船员的实操技能,针对目前船舶系泊操纵评估缺乏完整评价指标体系的问题,结合专家评估法和模糊综合评价法进行系泊操纵技能评估,构建每个评价指标的隶属度函数;采用层次分析法(AHP)确定每个评价指标的建议权重值和标准值,以确保评价结果准确可靠;利用三维虚拟船技术,根据各因素对系泊操纵的影响程度研发一套系泊操纵技能自动评估系统,实现对船舶系泊操作的全面评估。研究结果表明:该系统评估结果与专家评估结果相比,有较高的一致性,证明模型在评估船员系泊操纵技能方面的有效性和可靠性。

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.
