The use of linguistic information to model and manage uncertainty in Decision Making (DM) has been a key subject of many proposals in the literature. The 2-tuple linguistic model and its extensions in linguistic DM has been very successful and extensive due to their flexibility and accuracy. Flintstones is a novel fuzzy linguistic decision tool enhancement suite that implements tools to facilitate the solving of linguistic DM problems that model the linguistic information with such a model and its extensions. However, both the 2-tuple linguistic model and Flintstones can not deal with uncertain situations modelled linguistically in which experts hesitate among several linguistic terms. For these cases, recently, it has been proposed the use of Hesitant Fuzzy Linguistic Term Sets (HFLTS) that have attracted a lot of research interest, mainly regarding its application in DM. Hence in this contribution it is proposed an extended version of Flintstones that includes the ability and functionality of dealing with HFLTS in linguistic decision problems and enables the integration, validity and performance of hesitant linguistic decision models and operators.
