摘要 将导出有序加权平均(IOWGA)算子推广到不确定的环境下,即所给出的数据信息为区间数。提出了一种不确定导出有序加权几何平均(UIOWGA)算子。利用区间数比较的可能度公式,提出了一种决策信息的集结方法,最后的实例说明该方法的有效性和合理性。 The induced ordered weighted geometric averaging (IOWGA) operator is extended to accommodate uncertain condition where all input arguments take the form of interval numbers. A new operator, uncertain ordered weighted geometric averaging(UIOWGA) is p ility formula for comparing interval numbers,we propose a method to aggregate the information. The final example is to demonstrate the method is effective and reasonable.
