An Integrated Location-Routing Framework for Multi-Type Urban Waste Collection and Recycling System
VÃctor 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
VÃctor Blanco, Miguel MartÃnez-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
VÃctor 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
VÃctor Blanco, Miguel MartÃnez-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
VÃctor Blanco, Miguel MartÃnez-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
VÃctor Blanco, Diego Laborda, Miguel MartÃnez-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…
