RT journal article T1 Different optimum notions for fuzzy functions and optimality conditions associated A1 Osuna Gómez, Rafaela A1 Hernández Jiménez, Beatriz A1 Chalco-Cano, Yurilev A1 Ruiz Garzón, Gabriel A2 Estadística e Investigación Operativa K1 Fuzzy numbers K1 Crisp order relation K1 Interval order relation K1 Differentiable fuzzy mappings K1 Stationary fuzzy point K1 Fuzzy optimization AB Fuzzy numbers have been applied on decision and optimization problemsin uncertain or imprecise environments. In these problems, the necessity to defineoptimal notions for decision-maker’s preferences as well as to prove necessary andsufficient optimality conditions for these optima are essential steps in the resolutionprocess of the problem. The theoretical developments are illustrated and motivatedwith several numerical examples.
