An Integrated Location-Routing Framework for Multi-Type Urban Waste Collection and Recycling System
Víctor Blanco, J. Fernando Camacho-Vallejo, Yolanda Hinojosa
Urban waste collection and recycling systems face increasing operational and environmental challenges due to population growth, heterogeneous waste streams, traffic congestion, and…
Exact Mixed-Integer Conic Liftings for Queueing-Based CDN Design
Víctor Blanco, Miguel Martínez-Antón
We study a class of content delivery network design problems in which service performance is explicitly modeled through queueing-based response times. In contrast to standard formu…
Optimal Embedding of Wiring Diagrams in Constrained Three-Dimensional Spaces
Víctor Blanco, Gabriel González, Justo Puerto
This paper investigates the \emph{Wiring Diagram Problem} (WDP), a three-dimensional layout design problem arising in industrial applications such as cable harness design and pipel…
Exponential Conic Optimization for Multi-Regime Service System Design under Congestion and Tail-Risk Control
Víctor Blanco, Miguel Martínez-Antón, Justo Puerto
We study the design of single-facility service systems operating under multiple recurring regimes with service-level constraints on response times. Regime-dependent arrival and ser…
Structural and Solution Analysis for the Ordered Weber Problem under Spatial Uncertainty
Víctor Blanco, Miguel Martínez-Antón
We propose a general analytical framework for single-facility continuous location problems under spatial demand uncertainty. In contrast to classical formulations based on discrete…
On the Strength of Linear Relaxations in Ordered Optimization
Víctor Blanco, Diego Laborda, Miguel Martínez-Antón
We study the conditions under which the convex relaxation of a mixed-integer linear programming formulation for ordered optimization problems, where sorting is part of the decision…
A Unified Optimization Framework for Multiclass Classification with Structured Hyperplane Arrangements
Víctor Blanco, Harshit Kothari, James Luedtke
In this paper, we propose a new mathematical optimization model for multiclass classification based on arrangements of hyperplanes. Our approach preserves the core support vector m…
A Mathematical Optimization Approach to Multisphere Support Vector Data Description
Víctor Blanco, Inmaculada Espejo, Raúl Páez +1
We present a novel mathematical optimization framework for outlier detection in multimodal datasets, extending Support Vector Data Description approaches. We provide a primal formu…
Coordinating Drop-Off Locations and Pickup Routes: A Budget-Constrained Routing Perspective
Maria Albareda-Sambola, Víctor Blanco, Yolanda Hinojosa
We introduce in this paper a new variant of a location routing problem, to decide, the number and location of drop-off points to install based on the demands of a set of pick-up po…
A Novel Co-Evolutionary Algorithm for Solving a Bilevel Pricing and Hubs Location Problem under a Tree Topology
Víctor Blanco, José-Fernando Camacho-Vallejo, Carlos Corpus
This paper introduces the Bilevel Tree-of-Hubs Location Problem with Prices (BTHLPwP). The BTHLPwP is a multiple-allocation hub location problem in which, in addition to determinin…
Optimal Mediated Graphs: The role of Combinatorics in Conic Optimization
Víctor Blanco, Miguel Martínez-Antón
In this paper, we provide a unified definition of mediated graph, a combinatorial structure with multiple applications in mathematical optimization. We study some geometric and alg…
On the Complexity of p-Order Cone Programs
Víctor Blanco, Victor Magron, Miguel Martínez-Antón
This manuscript explores novel complexity results for the feasibility problem over -order cones, extending the foundational work of Porkolab and Khachiyan. By leveraging the int…
