摘要: 在直觉模糊集概念的基础上,通过对直觉模糊数加权的方法建立一种新的序关系。利用传统的序关系和新的序关系分别建立直觉模糊序决策信息系统。然后在定义的分配函数和分配协调集的基础上,给出对应的分配约简的判定定理和辨识矩阵,进而建立直觉模糊序决策信息系统的分配约简的具体方法。最后通过实例验证该方法的有效性。

Abstract: Based on intuitionistic fuzzy sets,a new order relation was established by weighting the intuitionistic fuzzy numbers.The intuitionistic fuzzy order decision information system was established by the traditional order relation and the new order relation respectively.Then,on the basis of the definition of assignment function and assignment of coordination sets,judgement theorem for the assignment reduction and discernibility matrixare was given in the system.Furthermore,the specific method of assignment reduction was established in an intuitionistic fuzzy ordered decision information system.Finally the effectiveness of the method is verified by an example.
