Similarity measures between intervals of linguistic 2-tuples and the intervals of linguistic 2-tuples weighted average operator

In this paper, we present a similarity measure between intervals of linguistic 2-tuples and present the intervals of linguistic 2-tuples weighted average operator. The proposed the proposed similarity measure between intervals of linguistic 2-tuples and the proposed intervals of linguistic 2-tuples weighted average operator can be used for fuzzy group decision making based on the linguistic 2-tuples representation.
