چکیده
Intuitionistic fuzzy linguistic numbers (IFLNs) are an extension of the linguistic variables and the intuitionistic fuzzy sets, which are proposed by Wang and Li (Wang J.Q., Li J.J. (2009) The multi-criteria group decision making method based on multi-granularity intuitionistic two semantics. Science & Technology Information (33), 8-9.). In this paper, we introduced some operational laws of IFLNs, and proposed the comparison method for IFLNs, firstly. Then, we developed an intuitionistic fuzzy linguistic numbers weighted geometric average (ILNWGA) operator, an intuitionistic fuzzy linguistic numbers ordered weighted geometric (ILNOWG) operator, and an intuitionistic fuzzy linguistic numbers hybrid geometric (ILNHG) operator which generalizes both the ILNWGA operator and the ILNOWG operator, and explored some desirable properties of these operators, such as commutativity, monotonicity, idempotency, and etc. Furthermore, we proposed a new method for the multiple attribute group decision making with intuitionistic fuzzy linguistic information based on these operators .Finally, we gave an illustrative example to verify the proposed method.

Arithmetic Aggregation Operators for Interval-valued Intuitionistic Linguistic Variables and Application to Multi-attribute Group Decision Making
The intuitionistic linguistic set (ILS) is an extension of linguisitc variable. To overcome the drawback of using single real number to represent membership degree and non-membership degree for ILS, the concept of interval-valued intuitionistic linguistic set (IVILS) is introduced through representing the membership degree and non-membership degree with intervals for ILS in this paper. The oper...

The aim of this manuscript is to present a new concept of hesitant q-rung orthopair fuzzy sets (Hq-ROFSs) by combining the concept of the q-ROFSs as well as Hesitant fuzzy sets. The proposed concept is the generalization of the fuzzy sets, intuitionistic fuzzy sets, hesitant fuzzy sets, and Pythagorean fuzzy sets as well as intuitionistic hesitant fuzzy sets (IHFSs) and hesitant Pythagorean fuz...
