二元语义的水资源管理方案多属性递阶群决策

Multi-Attribute Group Decision-Making for Water Resources Management Based on Two-Tuple Linguistic

基于二元语义的水资源管理多属性递阶群决策模型,将水资源管理决策群体分为基层技术组A、中层专家组B和高层管理组C,提出了二元语义决策评价准则,建立了A、B、C三层决策矩阵的联合矩阵;最后由联合矩阵求出全体专家的最满意方案。绵阳市水资源合理配置决策分析的实例应用结果表明,该决策模型既能合理集结不同层次决策群体的信息,又能避免语言评价信息集结和运算中出现的信息损失和扭曲,是一种可行的建模方法。

Water resources management often involves many complex factors,such as social values,economic development,environmental protec-tion and industry management. Usually,decision-making on water resources system is an uncertain,hierarchical,and multi-attribute group deci-sion-making process. In this paper,the conversion relationship between three types of weight function-whiten and two-tuple linguistic were studied and water resources management multi-attribute group decision-making model based on two-tuple linguistic was proposed. Decision groups of water resources management were classified into the technical group A of basic-level,the experts group B of middle-level and the management group C of high-level. Then it put forward water resources management decision-making criteria based on two-tuple linguistic and established the confederate matrix according to the decision-making matrices A,B and C;finally,it found out all expertsˊmost satisfying scheme by the conjoint matrix. The results of Mianyang Cityˊs water resources decision-making analysis show that the decision-making model can reasonably aggregate the information of different decision-making groups and avoid information loss and distortion in the aggregating and operations of linguistic assessment information.
