In this sense, first, an order relation will be defined for the interval space and, from this, it will be defined a solution concept for the interval problem in question. Subsequently, it will be shown that an interval problem is equivalent to a bi-objective problem. Finally, it will be established the necessary conditions of Fritz John and Karush-Kuhn-Tucker types for the interval-valued optimization problem.500-507engClassical necessary condition of Fritz JohnInterval optimization problemsKarush-Kuhn-TuckerLU order relationLU solutionsMulti-objective optimization problemsNecessary optimality conditions for the LU-solutionTrabalho apresentado em evento10.1007/978-3-319-95312-0_43Acesso aberto2-s2.0-85051030695
