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。
藉助改進熵權法對評價指標進行賦權,在灰關聯分析和模糊物元分析理論的基礎上,建立瞭改進熵和灰關聯分析的模糊物元分析模型。根據灰色關聯度的大小對評價對象進行排序,併將其應用到農業節水灌溉項目的優選中,說明此模型的閤理性。

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 .
