摘要
针对大型灌区节水改造项目效益评价多属性、多指标的特点,提出了一种改进的TOPSIS评价方法。为了避免权重确定的主观性,引入信息熵来计算各评价指标的权重,建立了基于熵权的综合评价模型,并将该方法应用于广西壮族自治区百色市右江灌区节水改造项目效益评价中。结果表明,该模型计算简单方便,结果合理。
An improved TOPSIS evaluation method,which aimed at the multi-attribute,multi-index characteristics of benefit evaluation of water-saving reconstruction project in Large-scale irrigation district,was proposed in this paper.In order to avoid the subjectivity of determining the weight coefficient,information entropy was introduced to calculate the weight coefficient of each index and one comprehensive evaluation model based on entropy was established.Moreover,the method was applied to comprehensive evaluation of water-saving reconstruction benefit in YouJiang irrigation district of Baise City,Guangxi Zhuang Autonomous Region.The results indicated that the model calculation was simple and convenient,its result was reasonable.
