摘　　要：给出了求解属性值为语言区间的多属性决策问题的新算法。其主要思想是将语言区间中语言标度用模糊集来表示,通过去模糊化方法将语言区间转化成区间数,用已有的属性值为区间数的决策方法进行决策。实例说明上述方法的具体操作过程及其有效性。A new method for calculating multi-attribute decision making on linguistic interval information is given.The fundamental ideas are as follows.Firstly,fuzzy sets are used to stand for the linguistic scale in linguistic intervals.Then the above linguistic intervals are transformed into interval numbers by the methods of defuzzifying.Finally,already existed approaches for multi-attribute decision making with interval numbers information are used to make decision.A practical example is provided to illustrate the operation and show the effectiveness of this method.

关 键 词：语言区间 模糊集 去模糊 多属性决策
