定义了直觉纯语言集及其运算法则和直觉纯语言变量的数学期望和精确函数,提出了一些基于直觉纯语言评估标度及其运算法则的信息集结算子。在此基础上,给出了一种专家权重、属性权重及属性值均以语言标度形式给出的直觉纯语言信息集结方法,并将此方法应用到多属性群决策中,实例分析表明了该方法的有效性和可行性。
Intuitive pure linguistic set, as well as its operational laws, expected values and accuracy function are defined. Some new intuitive pure linguistic operators based on the intuitive pure linguistic evaluation scale and the operational laws are developed. Also, a method for aggregating intuitive pure linguistic information, in which all expert weights, attribute weights, attribute values take the form of linguistic labels is proposed. Moreover, the method is applied to the multiple attribute group decision making. And finally, the feasibility and effectiveness of the method are shown by an illustrative example.
