Abstract: Assuming that X is a Tychonoff space, we obtain necessary and sufficient conditions for a function f∈RXto belong to the closure in RXof a pointwise bounded family F in C(X), the ring of real-valued continuous functions on X. In other words, if M(X) stands […]

Abstract: The present paper deals with uncertain linear optimization problems where the objective function coefficient vector belongs to a compact convex uncertainty set and the feasible set is described by a linear semi-infinite inequality system (finitely many variables and possibly infinitely many […]

Abstract: This work provides new insights on bi-criteria resource-constrained project scheduling problems. We define a realistic problem where the objectives to combine are the makespan and the total cost for […]

Abstract: In the technical efficiency evaluation area, it may happen that many observations obtain a similar relative technical efficiency status, making it difficult to discriminate between them. The determination of super-efficiency has been a […]
