水利工程建设方案决策是多目标综合评价问题,系统指标信息具有复杂、多变,模糊、不确定等特点,采用Vague集相似度量评价模型构建水利工程建设方案综合决策模型,建立基于Vlague集的指标隶属度计算方法,构造基于Vague集相似度的多目标方案评价.针对建设方案决策评价指标的不确定性,通过肯定、踌躇、否定的Vague集相似度量概念延伸了传统模糊集的评价、分析方式.将方法应用于水利工程建设方案决策实例,取得较为满意的结果,表明了方法的合理可行性,为水利工程的建设方案评价提供了科学决策的新途径.
The decision-making of water conservancy construction project is a multi-objective comprehensive evaluation problem. The system index information is complex, changeable, fuzzy, uncertain and so on. Adopting the similarity measure evaluation model of Vague sets to construct the comprehensive decision-making model of water conservancy project construction, establishing the index based on Vlague set The method of membership degree is used to construct the evaluation of multi-objective programs based on the similarity of Vague sets.According to the uncertainty of decision indexes of construction schemes, the evaluation of traditional fuzzy sets is expanded through the concepts of similarity, hesitancy and negation of similarity measure of Vague sets The method is applied to the decision example of water conservancy project construction, and the satisfactory result is obtained, which shows that the method is reasonable and feasible, which provides a new way of scientific decision for the construction project evaluation of water conservancy project.
