摘　　要：[目的]极地邮轮减摇鳍选型要考虑包括环境适应、设备性能等多方面因素,主观判断往往难以选出最优的减摇鳍。针对极地邮轮减摇鳍的选型,提出基于组合赋权-TOPSIS法的综合选型评价方法。[方法]以满足极地船舶PC6规则作为某8035 t极地邮轮减摇鳍的选型原则,通过鳍面积的经验公式计算得出减摇鳍设备选型的约束条件,进而确定3种设计方案;咨询业内专家,构建由5个一级指标和14个二级指标组成的选型评价指标体系;通过层次分析法(AHP)和熵权法(EWM)确定指标的权重;运用逼近理想解的排序方法(TOPSIS)计算各方案与理想解的贴近程度。[结果]根据排序结果,确定方案1(Aquarius A100减摇鳍)为符合决策者需求的最优减摇鳍。[结论]该方法对极地邮轮的减摇鳍选型有一定指导意义,降低了建造者和决策者选型时的盲目性。[Objectives]Many factors should be taken into consideration in the selection of a fin stabilizer for a polar cruise ship,such as environmental adaptation and device performance,and it should not be chosen via subjective judgment.To this end,a comprehensive fin stabilizer selection and evaluation method based on a combined weighting-TOPSIS(technique for order preference by similarity to ideal solution)method is pro-posed.[Methods]The selection principle of a fin stabilizer for a polar cruise ship with a gross tonnage of 8035 is confirmed according to the PC6 guidelines for polar class ships,and the initial area of the fin stabilizer is calculated using the experimental mathematical model.Three design schemes are put forward for the fin stabil-izer.A selection and evaluation index system is built by consulting experts,including five primary indexes and fourteen secondary indexes.The weights of the indexes are determined using the analytic hierarchy process(AHP)and entropy weight method(EWM),and the TOPSIS method is introduced to calculate the degree of closeness between the alternative and ideal solutions.[Results]According to the ranking results,Design Scheme 1(Aquarius A100 fin stabilizer)is selected as the optimal fin stabilizer for meeting the decision-makers'requirements.[Conclusions]The method proposed in this study has valuable guiding significance for the selection of fin stabilizers for polar cruise ships by reducing the blindness of the shipbuilders and de-cision-makers.
