Abstract: Because of complexity, many aggregated methods for interval multiattribute group decision are difficult to general decision makers, a new way has been proposed in this paper. This method puts forward basic interval conception to aggregation and provides direct solution schematically. It is easier and more intuitive. Finally, as compared with the results of literature method, this has been demonstrated as an effective method.

摘要： 针对一般区间多属性群决策集结算法复杂,普通决策者难以掌握问题,提出了一种新的相对简单方
便的集结方法。该方法利用区间评价值基础区间的分解进行求解,为提供直观求法,还给出了相应图解。最后用两
个算例与文献方法进行了结果比较分析,两者结果一致,说明了文章方法的有效性。
