摘要
直觉模糊熵是直觉模糊集理论中的一个重要概念,反映了直觉模糊集的模糊程度和不确定程度.首先给出一种新的直觉模糊熵,并运用到多属性直觉模糊决策问题中.决策时根据直觉模糊熵计算属性权重,再综合决策者的偏好对各属性权重进行修正,然后使用直觉模糊集结算子和得分函数对方案进行排序,从而获得最优方案.
Intuitionistic fuzzy entropy is an important conception in the theory of intuitionistic fuzzy set,which indicates fuzziness and uncertainty about an intutionistic fuzzy set.A new method of computing intuitionistic fuzzy entropy is investigated and applied to multi-attribute intuitionistic fuzzy decision making problem.According to the intuitionistic fuzzy entropy,the attribute＇s weights are obtained.And combinating with decision maker＇s preference, the attribute＇s weights are revised.Then an intuitionistic fuzzy rally operator and scoring function are used in the process of ranking all alternatives,then the optimal decision can be found.
