2020年6月16日，数据恢复四川省重点实验室大数据智能决策方向许雷老师团队在国际期刊《Journal of Intelligent & Fuzzy Systems》（IF：1.637，SCI 四区）在线发表题为《Linguistic interval-valued Intuitionistic Fuzzy Copula power Aggregation Operators for Multiattribute GroupDecision Making》的研究论文，文章研究基于区间语言直觉模糊数的多属性群决策方法。

为了更好地处理决策问题中的不精确和不确定信息，文章提出了基于区间语言直觉模糊数的集合算子，该算子结合了Couplas和扩展Couplas，幂平均算子和语言区间值直觉模糊信息。在Couplas和扩展Couplas的基础上，提出了几种聚合算子对语言区间值直觉模糊信息进行聚合，以提供决策支持，并讨论了所提出聚合算子的性质。

Abstract：For the sake of better handle the imprecise and uncertain information in decision making problems(DMPs), linguistic interval-valued intuitionistic fuzzy numbers(LIVIFNs) based aggregation operators (AOS) are proposed by combining extended Couplas (ECs), extended Co-copulars (ECCs), power average operator and linguistic interval-valued intuitionistic fuzzy information(LIVIFI). First of all, ECs and ECCs, some specifics of ECs and ECCs, score and accuracy functions of LIVIFNs are gained. Then, based on ECs and ECCs, several aggregation operators are proposed to aggregate LIVIFI, which can offer decision makers (DMs) desirable generality and flexibility. In addition, the desired properties of proposed AOS are discussed. Last but not least, a MAGDM approach is constructed based on proposed AOs; Consequently, the effectiveness of the proposed approach is verified by a numerical example, and then the advantages are showed by comparing with other approaches.
