摘要
分析国内外船舶能耗评估的发展现状,采用模糊评判的数学建模方法对船舶能耗进行评估。通过专家调查法对初步建立的一级模糊评判中六大指标体系采用权重分析法确定其权重向量,同时采用同种方法确定二级指标的权重向量。再通过模糊评判对某船型进行能耗评估。通过分析得出,模糊评判适用于船舶能耗的综合评价,并对今后进行船舶能耗评判具有指导意义。
Present state of ship energy consumption evaluation in China and abroad is analyzed.A mathematical modeling method of fuzzy evaluation is adopted to evaluate ship energy consumption.Six indexes for fuzzy evaluation are set up,and the weight vectors of the index system in level one evaluation and level two evaluation are both determined through expert investigations.The energy consumption evaluation of a ship is carried out.It is indicated by analysis that fuzzy evaluation is suitable for evaluating ship energy consumption.The result is instructive for ship energy consumption evaluation.
