Models for MAGDM with dual hesitant -rung orthopair fuzzy 2-tuple linguistic MSM operators and their application to COVID-19 pandemic.

In this article, we introduce dual hesitant -rung orthopair fuzzy 2-tuple linguistic set (DH-ROFTLS), a new strategy for dealing with uncertainty that incorporates a 2-tuple linguistic term into dual hesitant -rung orthopair fuzzy set (DH-ROFS). DH-ROFTLS is a better way to deal with uncertain and imprecise information in the decision-making environment. We elaborate the operational rules, based on which, the DH-ROFTL weighted averaging (DH-ROFTLWA) operator and the DH-ROFTL weighted geometric (DH-ROFTLWG) operator are presented to fuse the DH-ROFTL numbers (DH-ROFTLNs).
