摘　　要：针对船舶操纵性评价中存在的问题,在深入研究各种系统评价方法的基础上,提出了一种基于灰关联分析和逼近理想解法(TOPSIS)的船舶操纵性能综合评价方法。该方法运用灰关联分析理论,计算评价指标的灰绝对关联度及评价指标的权重;利用TOPSIS法,建立加权评价矩阵,引入Hausdorff距离代替欧式距离,计算各评价对象与理想方案的相对接近度,并依据相对接近度对各参评船型的操纵性作出优劣排序。应用结果表明,该方法合理有效,实用性强。With the aim of improving the evaluation of ship maneuverability, through investigating various kinds of e- valuation methods, an evaluation method of ship maneuverability is suggested based on grey relational theory and TOPSIS（Technique for Order Preference by Similarity to Ideal Solution）. , The grey absolute correlation degrees of evaluation indexes and the weight of each index are work out by means of the grey correlation analysis theory. Fol- lowing TOPSIS, the weighted decision matrix is constructed on the basis of Hausdorff distance instead of Euclidean distance and the proximity of performances of designs to the benchmark are calculated, e The design of optimal ship maneuverability can be decided according to the smallest relative degree of proximity. The rationality and effective-ness of the method is validated by practical data set.
