| 摘 要： | 节水灌溉项目评价中各指标存在不确定性和模糊性,将熵值理论与模糊物元建模相结合,建立了基于熵权的模糊物元节水灌溉项目综合评价模型.引用信息熵所反映数据本身的效用值来计算指标的权重系数,有效地避免了权重分配中主观因素影响问题.该模型以一种新的方法进行节水灌溉项目综合评价,并结合实例进行应用,通过与模糊综合评判法比较,进一步验证了该模型的可行、简便和实用.

| Abstract: | In view of the uncertainty of indexes for evaluation of water-saving irrigation project investment,the entropy value theory is combined with fuzzy matter-element method to establish a fuzzy matter-element model based on coefficient of entropy for the comprehensive evaluation of water-saving irrigation project.The coefficients of weight in this model are derived from the avail value of data reflected by the information entropy.Through this method,the problem of the influence of subjective factors in weight a... |
