一种基于三参数区间灰色语言变量的多属性群决策方法

针对属性值为三参数区间灰色语言变量的不确定型多属性决策问题进行了研究,本文将语言变量和三参数区间数融合, 提出了三参数区间灰色语言变量的概念, 定义了三参数区间灰色语言变量的运算规则和可能度公式,在此基础上建立了基于投影模型的三参数区间灰色语言变量的多属性群决策方法。最后,通过对移动银行服务质量评估案例验证本模型的有效性。

A Multiple Attribute Group Decision Making Model Based on Three-para Meter Interval Grey Linguistic Variable

A method based on the three-parameter interval grey additive linguistic variables is presented to solve multiple attribute group decision making problems, in which the attribute values take the form of the grey additive linguistic variables. Firstly, some properties are defined, such as the concept and the relational calculation rules of grey additive linguistic variables. Then, a multiple attribute group decision making problem model based on three-parameter interval grey additive linguistic variables and project model are used to solve the mobile quality of service evaluation problems. At last, an example involved in the mobile bank shows the effectiveness of this method, and the result shows that information security and mobile services may be the most important evaluation indicators.
