Application of Scale Transformation based on Fuzzy Analytic Hierarchy Process to Water Right Allocation in Ningxia Irrigated Area
基于标度转换的模糊层次分析法在宁夏灌区水权分配中的应用

With the development of Yellow River irrigation in Ningxia,it is imperative to build a new pattern of water right allocation.In terms of the principles of efficiency,equity and sustainability,index system of initial allocation of water right is presented and hierarchical structure model is developed in this paper.Then with the scale transformation method,the anticlastic "1-9 scale" is transformed to complementary "0.1-0.9 nine scales",which constitutes fuzzy complementary judgment matrix associated with the index system and the matrix is fuzzily and hierarchically analyzed.Furthermore,this paper introduces Fuzzy Analytic Hierarchy Process(FAHP)into initial allocation of water right.Finally,the developed method is applied to water right allocation in Ningxia irrigated area and satisfactory results are obtained.
