摘　　要：本文研究了区间数群决策信息的集结方法。基于区间数两两比较的可能度矩阵公式和互补判断矩阵的排序公式,推广了文献[3]提出的不确定型OWGA算子,提出了一种组合不确定型OWGA算子,给出了其在应用过程中的具体步骤,并提出了一种相应的集结群决策信息的方法,最后通过一个算例说明了该方法的有效性与可行性,并与文献[3]的结果作了对比分析。The method of aggregating the interval information is studied in group decision making. Based on the formula of possibility degree and the priority method of fuzzy complementary judgement matrix, the uncertain OWGA operator proposed in reference[3] is generalized. A combined uncertain OWGA operator and its application procedures are proposed, and a method based on the combined uncertain OWGA operator for aggregating information in group decision making is presented. Finally, a numerical example is given to show the feasibility and effectiveness of the proposed method. It is also compared with the result of reference [3].
