The generalized interval-valued trapezoidal fuzzy best-worst method (GITrF-BWM) provides more reliable and consistent criteria weights for multiple group decision making (MCGDM) problems. In this study, GITrF-BWM is integrated with the extended TOPSIS (technique order preference by similarity to ideal solution) VIKOR (visekriterijumska optimizacija i kompromisno resenje) methods selection of op...
