| 摘 要： | 针对节灌工程项目决策中各指标具有独立性和不相容性,以及指标的选择与评价标准具有一定模糊性的特点,提出了一种基于模糊物元分析的项目决策新方法。通过建立从优隶属度和关联度模糊物元来形成判断矩阵,采用均方差计算各指标的权重,然后根据计算获得关联度的大小对各投资方案进行排序,从而确定最优决策方案。将该模型应用在黄河流域节灌工程项目决策中,验证了其可行性及合理性。

| Abstract: | According to the independence and non-compatibility of indexes in the decision-making of water-saving irrigation and the fuzziness in the choice of indexes and criterion,a new method based on the fuzzy matter-element is proposed for the project decision.The model begins with building the matter-element of optimal subordinate degree and relational grade and calculating the coefficient of weight by standard deviation.At last,the optimal scheme is selected by the relational grade.The outcome of the application to the water-saving irrigation decision in the watersheds of the Yellow River shows that the model is feasible and reasonable. |
