Interval type-2 hesitant fuzzy Entropy-based WASPAS approach for aircraft type selection

Choosing the most appropriate aircraft type for a given route is one of crucial issues that decision makers at airline companies have to address under uncertainty based on various commercial, marketing and operational criteria. A novel multi-criteria making approach integrating Entropy-based Weighted Aggregated Sum Product Assessment (WASPAS) method interval type-2 hesitant fuzzy sets (IT2HFS) introduced tackling this problem tested using particular case study obtained from full service carrier in Turkey. This contributes representing handling degrees process selection IT2HFS. The results showed Airbus 32C suitable alternative between Kuwait Istanbul airports. experts evaluated confirmed proposed when compared four other IT2HFS approaches.
