Integration of hesitant fuzzy set and interval type-2 fuzzy set in analytic hierarchy process
In the broad application of the analytic hierarchy process (AHP) to address decision problems pertaining to multi-criteria decision-making, crisp values are often used to represent the linguistic judgement made by experts or decision makers. The numerous fuzzy approaches proposed in prior studies, such as interval type-2 fuzzy set (IT2FS) and hesitant fuzzy set (HFS), may serve as alternative models to tackle both vagueness and uncertainty during the decision process. As such, this study offers a new AHP framework characterised by the integration of IT2FS and HFS for
