Merigó Lindahl, José M.Gil Lafuente, Anna MariaYu, DejianLlopis-Albert, Carlos2018-10-182020-07-312018-071568-4946https://hdl.handle.net/2445/125426This article presents a new aggregation system applied to fuzzy decision making. The fuzzy generalized unified aggregation operator (FGUAO) is a system that integrates many operators by adding a new aggregation process that considers the relevance that each operator has in the analysis. It also deals with an uncertain environment where the information is studied with fuzzy numbers. A wide range of particular cases and properties are studied. This approach is further extended by using quasi-arithmetic means. The paper ends studying the applicability in decision making problems regarding the European Union decisions. For doing so, the work uses a multi-person aggregation process obtaining the multi-person - FGUAO operator. An example concerning the fixation of the interest rate by the European Central Bank is presented.8 p.application/pdfengcc-by-nc-nd (c) World Federation on Soft Computing (WFSC), 2018http://creativecommons.org/licenses/by-nc-nd/3.0/esLògica borrosaSistemes borrososÀlgebres d'operadorsFuzzy logicFuzzy systemsOperator algebrasinfo:eu-repo/semantics/article6819552018-10-18info:eu-repo/semantics/openAccess
