A novel ordered weighted averaging weight determination based on ordinal dispersion. International Journal of Intelligent Systems. 2019 34(9): 2291-2315.0884-81731098-111X10.1002/int.22168https://hdl.handle.net/20.500.14352/110904Inspired by the Zadeh approach to fuzzy connectives in fuzzy set theory and by some applications, we introduce and study set-based extended functions, and in particular, set-based extended aggregation functions. These functions reflect neither reordering nor repetition of input values, and, linking different arities, they introduce serious constraints for extended functions. A complete characterization of set-based extended (aggregation) functions is given, and some constructions of such functions are also proposed, including several examples.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://onlinelibrary.wiley.com/doi/full/10.1002/int.22168open accessAggregation operatorsDecision‐makingOrdinal dispersionOWAEstadística matemática (Matemáticas)1299 Otras Especialidades Matemáticas1209 Estadística
