农业节水灌溉项目优选-基于改进模糊物元分析模型

摘要

Evaluation indexes were weighted by improved entropy weight method , fuzzy matter-element analysis model based on improved entropy and grey relational analysis on the basis of fuzzy matter -element analysis and grey relational analysis was builded ,evaluation objects are ranked by sizes of grey relational degree and applied the model to optimal se -lection of agricultural water saving irrigation projects ,the case proved the model effective .%借助改进熵权法对评价指标进行赋权，在灰关联分析和模糊物元分析理论的基础上，建立了改进熵和灰关联分析的模糊物元分析模型。根据灰色关联度的大小对评价对象进行排序，并将其应用到农业节水灌溉项目的优选中，说明此模型的合理性。
