Namely, we apply the weighting technique to find efficient solutions to these problems, defined in terms of (Formula presented.) -efficiency and weak (Formula presented.) -efficiency. Thus, an auxiliary weighting extremization problem related to the considered multi-cost interval-valued extremization problem is introduced. Under appropriate convexity hypotheses, an equivalence is established between the (weakly) (Formula presented.) -efficient solution of the multi-cost interval-valued extremization problem and the optimal solution of the auxiliary weighting extremization problem. Also, a numerical example is formulated to support the theoretical developments derived in the paper.eninfo:eu-repo/semantics/openAccessConvex Interval-valued Controlled FunctionalLU-efficient SolutionMulti-cost Interval-valued Extremization ProblemsWeighting MethodArticle15810.3390/info15080455Q2N/A
