中文摘要：
针对传统VIKOR方法不能处理不确定语言信息的缺陷，本文在VIKOR方法的基础上提出了一种基于区间二型模糊的VIKOR扩展方法用于解决多属性决策问题。首先介绍了区间二型模糊的概念、运算法则，接着定义了一种新的计算区间二型模糊集之间的距离公式，在此基础上提出基于区间二型模糊的VIKOR扩展方法。最后，通过一个算例说明该方法的有效性和合理性。
英文摘要：
With respect to the defect that traditional VIKOR method could not deal with uncertain linguistic information, a method of extended VIKOR based on interval type-2 fuzzy sets is presented to solve the multiple attribute decision making problems. Firstly, the concepts and computation rules are introduced. Then, a new distance formula between two interval type-2 fuzzy sets is defined. On the basis of which, an extended VIKOR method based Interval type-2 fuzzy sets arc proposed. Finally, an example is given to illustrate the validity and feasibility of the proposed method.
