摘　　要：针对船舶操纵性评价过程中存在的评价指标权重确定主观性强和分配不统一等问题,提出一种基于主成分分析(principal component analysis,PCA)的船舶操纵性综合评价方法。该方法以国际海事组织(International Maritime Organization,IMO)船舶操纵性指标为基准,根据操纵性指标的主成分贡献率确定指标权重,客观地算出船舶操纵性综合评价值。通过对8艘船的操纵性试验数据进行分析计算,得到每艘船的船舶操纵性综合评价值。结果表明,该方法不仅在理论上科学、客观,而且在实际应用中简单、可靠,有助于提高船舶操纵性综合评价的客观性。Aiming at the problems of the stronger subjectivity of evaluation index weight determination and the inconsistence of weight distribution in the evaluation of ship maneuverability,a comprehensive evaluation method of ship maneuverability based on the principal component analysis(PCA)is proposed.The IMO ship maneuverability indexes are taken as evaluation indexes,the weights of indexes are determined according to their principal component contribution ratios,and the comprehensive evaluation value of ship maneuverability is calculated objectively.By analyzing and calculating the maneuverability experimental data of eight ships,the comprehensive evaluation value of each ship is obtained.The results show that,the method is not only scientific and objective in the theory,but also simple and reliable in the practical application.It is helpful to improve the objectivity of comprehensive evaluation of ship maneuverability.
