摘 要:
在总结现有研究与评价方法的基础上,构建了基于最优组合赋权模糊物元模型的节水灌溉项目评价模型。首先,采用G1法和改进熵权法确定指标的主客观权重;然后,运用最小鉴别信息原理进行组合赋权,得到兼顾主客观因素的权重。其次,利用物元可拓法和理想解法求解理想模糊物元和负理想模糊物元,并根据欧式范数计算确定各评价对象的相对关联度。最后,通过在某地区节水灌溉项目投资决策的实例分析,验证了所提方法的可行性和有效性。

摘 要:
On the basis of summarizing the existing research and evaluation methods,this paper constructs a water-saving irrigation project evaluation model based on the optimal combination weighted fuzzy matter-element model. Firstly,the G1 method and the improved entropy weight method are used to determine the subjective and objective weights of the index. Then,the principle of minimum discriminating information is used to combine the weights,and the weights of both subjective and objective factors are obtained. Secondly,the objective fuzzy extension method and the ideal solution method are used to solve the ideal fuzzy matter element and the negative ideal fuzzy matter element,and the relative relevance of each evaluation object is determined according to the European norm calculation. Finally,the feasibility and effectiveness of the proposed method are verified by an example of investment decision-making in a water-saving irrigation project in a certain area.
