基于DHGF法的船舶操纵性综合评价

Integrated Evaluation of Ship Maneuverability Based on DHGF Algorithm

在深入研究船舶的操纵性能的特点和各种系统评价方法的基础上,提出一种使用方便且行之有效的船舶操纵性能的综合评价方法。首先,在船舶固有操纵性基础上,建立了操纵性的指标体系。在深入研究Delphi法、层次分析法(AHP)、灰色关联度法以及模糊综合分析法的基础之上,提出DHGF集成法,阐述了该方法的构造原理和计算步骤。最后,将DHGF理论应用于船舶操纵性评价的实践中,得出船舶操纵性评价的结果与实际情况相同。提出DHGF集成法不仅在理论上具有优越性、科学性,在应用中也具有可靠性和可操作性,从而对工程上船舶的操纵性评价具有一定参考价值。

Based on the study of ship maneuverability characteristics together with a variety of performance evaluation systems,a user-friendly and effective control of ship performance evaluation method is presented.Firstly,the index system of manipulation was set based on the inherent maneuverability of ship,and available methods including the Delphi method,the Analytical Hierarchy Process（AHP）,the gray correlation method as well as the comprehensive fuzzy analysis were reviewed,and an DHGF integrated method was therefore proposed on these grounds,architecture principles of this method and the calculation procedure are illustrated.Applying the DHGF theory in an evaluation of ship maneuverability shows that the evaluated results agree with the realistic one.It proves that the DHGF integrated method has advantages both in theory and being able to use reliably and practically,providing reference for evaluation of ship maneuverability in engineering design.
