不同直觉模糊数在信息集结过程中,其隶属度与非隶属度之间可能存在着相互影响.提出了直觉模糊数上的改进的乘法运算和幂运算,重新给出了直觉模糊加权几何平均算子和直觉模糊有序加权几何平均算子的表达式,并研究了他们的一些性质.最后通过实例说明了新的IFWGA集成算子在多属性决策中的应用是可行和有效的.
There may also exisit some interactions between membership function and non- membership function in the process of aggregating different intuitionistic fuzzy numbers, we propose the improved operations laws over intuitionistic fuzzy numbers, including multipli- cation and power operation. Based on which, we present the intuitionistic fuzzy weighted geometric aggregation (IFWGA) operator and the intuitionistic fuzzy ordered weighted geo- metric aggregation (IFOWGA) operator. Moreover, the corresponding expressions are given, and the properties of these operators are investigated. Finally, an example shows the fea- sibility and validity of the new operators in the application of multiple attributes decision making.
