Extended hesitant fuzzy SWARA techniques to examine the criteria weights and VIKOR method for ranking alternatives

The SWARA method is attributed for determining relative weights and significance of each criterion. SWARA provides the opportunity for decision makers or experts to provide their preferences depending on the ongoing situation and conditions for calculating weights. The VIKOR method is utilized for ranking the alternatives and also selecting the best alternative from the available alternatives over the conflicting criteria. In this paper, we extend the Stepwise Weight Assessment Ratio Analysis (SWARA) method with hesitant fuzzy (HF) set for calculating the weights of the criteria and ranking the alternatives by using VIKOR method. Finally, the proposed HF-SWARA I and HF-SWARA II methods are demonstrated through numerical examples.
