摘要 犹豫模糊语言集（hesitant fuzzy linguistic term set，HFLTS）是指语言变量的取值为语言术语集的一个有序且连贯的子集.文章对基于HFLTS的理论发展进行了综述.首先介绍了HFLTS的含义及起源，随后分别对犹豫模糊语言信息的融合理论、测度理论、偏好关系理论以及决策方法进行了概述.最后展望了HFLTS理论未来的研究方向.
Abstract：Hesitant fuzzy linguistic term set (HFLTS) is defined as an ordered and consecutive subset of the linguistic term set for a linguistic variable. This paper carries out some states of the art review over the development of HFLTS theory. Firstly, we introduce the definition and originality of the HFLTS, and then conduct the review from four aspects, which are the hesitant fuzzy linguistic fusion theory, the hesitant fuzzy linguistic measurement theory, the hesitant fuzzy linguistic preference relation theory and the hesitant fuzzy linguistic decision making methodologies. Finally, we outline the future research directions on qualitative decision making with hesitant fuzzy linguistic information.
