摘　　要：基于IOWGA算子和C-OWGA算子,提出一种IC-OWGA算子,讨论了该算子的优良性质.针对区间数互反判断矩阵提出一种连续偏好矩阵的概念,定义了一种DIC-OWGA算子,并给出了一种基于该算子的区间数群决策方法,最后通过算例说明了该方法的可行性.The induced continuous ordered weighted geometric averaging （IC-OWGA） operator is proposed based on the induced ordered weighted geometric averaging （IOWGA） operator, the continuous interval argument ordered weighted geometric averaging （C-OWGA） operator and some properties are studied. Based on the interval number complementary judgment matrix, the interval continuous complementary preference matrix is proposed and the induced continuous ordered weighted geometric averaging （DIC-OWGA） operator is defined on the basis of the deviation of assessment level of experts. A method of interval number multi-attribute group decision making based on the DIC- OWGA operator is given. Finally, an illustrative example is given and the results show that the method is feasible.
