基于风险偏好的区间直觉模糊多属性决策方法

Interval valued intuitionistic fuzzy multiple attribute decision making based on risk preference

在多属性决策中,决策者的风险偏好在很大程度上影响决策结果.根据区间直觉模糊数的特点和多属性决策的特征,引进风险偏好因子并构建基于风险偏好的区间直觉模糊得分函数,研究其性质及排序规则;结合区间直觉模糊加权平均算子,建立基于风险偏好的区间直觉模糊多属性决策方法.算例结果表明:该方法能够很好地体现决策者的风险态度,具有实用性和有效性.

In multiple attribute decision making,decision maker's risk preference can affect decision results to a large extent.According to the characteristics of the interval valued intuitionistic fuzzy number and the features of the multiple attribute decision making,we introduce the risk preference factor to construct the interval valued intuitionistic fuzzy score function based on the risk preference studying the nature and the ranking rules;then we establish the interval valued intuitionistic fuzzy multiple attribute decision making method based on the risk preference by combining the interval valued intuitionistic fuzzy weighted averaging operator and apply it to a specific calculation example.The results show that the method can perfectly reflect the risk attitude of decision makers,which is practical and effective.
