船舶绿色智能技术应用综合评价方法

Research on the comprehensive evaluation method of green and intelligent technology application in ships

针对船舶绿色智能技术应用评价指标众多、且部分指标属性值具有模糊性和随机性的问题,提出基于混合随机占优的不确定性多属性指标综合评价方法。即采用模糊语言变量-UOWA算子结合的指标属性值量化方法,确定具有模糊性的单指标属性值,通过随机模拟的指标属性值量化方法,确定具有随机性的单指标属性值。在此基础上,构建混合多属性决策模型,通过确定各指标的混合占优关系和混合占优度,建立综合混合占优度矩阵,并利用Promethee II方法择优方案。最后将该方法应用于长江7 500 t散货示范船,验证了综合评价方法的有效性。

Aiming at the problem that there are many evaluation indexes of green intelligent technology application in ships and some index attribute values are fuzzy and stochastic, an uncertain multi-attribute index comprehensive evaluation method based on mixed stochastic dominance is proposed. In this method, the single index attribute value with fuzziness is determined by using the index attribute value quantification method combined with fuzzy linguistic variable-UOWA operator, and the single index attribute value with randomness is determined by the index attribute value quantification method of random simulation;on this basis, the mixed multi-attribute decision model is constructed, and the integrated mixed dominance matrix is established by determining the mixed dominance relationship and mixed dominance degree of each index, and The Promethee II method was used to select the optimal solution. Finally, the method was applied to 7500 t bulk carrier demonstration vessel in the Yangtze River to verify the effectiveness of the comprehensive evaluation method.
