摘要: 基于不确定语言变量和区间模糊数,提出了不确定区间隶属度语言变量的概念,定义了不确定区间隶属度语言变量的运算规则、大小比较方法,给出了不确定区间隶属度语言变量的加权算术平均算子、加权几何平均算子及其相应性质,并将这些算子应用于属性权重确知且属性值以不确定区间隶属度语言变量形式给出的不确定多属性群决策问题中,通过示例验证了基于不确定区间隶属度语言变量信息的多属性群决策方法的有效性和可行性。

Abstract: Based on the uncertain linguistic variables and the interval fuzzy number, uncertain interval membership linguistic number(UIMLV)is introduced in this paper, then some basic definition such as the operational laws, score function, accuracy function and comparison rules of the UIMLV are defined. Next, the uncertain interval membership linguistic weighted average(UIMLWA)operator, the uncertain interval membership linguistic weighted geometric(UIMLWG)operator are presented, and some desirable properties are discussed. Finally, an approach is proposed under the uncertain interval membership linguistic environment, and an illustrative example is given to verify the effectiveness and feasibility of the proposed approach.

Key words: uncertain interval membership linguistic variable, weighted average operator, weighted geometric operator, multiple attribute group decision making
