英文摘要：

The multiple attribute group decision making problem is investigated, in which the information about attribute is expressed by interval linguistic assessment information, a method of multiple attribute group decision making based on interval two-tuple linguistic information is presented. The definition of interval two-tuple linguistic is given, and some aggregation operators are proposed, then the property of these operators is analysised. Thought investigating the possibility degree of interval interval two-tuple linguistic information, the ranking is gained by the result of aggregation. A practical example is illustrated to show the feasibility and availability of the developed method.
