A Novel Multiobjective Formulation of the Robust Software Project Scheduling Problem
Chicano, Francisco; Cervantes, Alejandro; Luna, Francisco; Recio, Gustavo (2014-10-07)The Software Project Scheduling (SPS) problem refers to the distribution of tasks during a software project lifetime. Software development involves managing human resources and a total budget in an optimal way for a ... -
Addressing the 5G cell switch-off problem with a multi-objective cellular genetic algorithm
Luna, Francisco; Luque-Baena, Rafael Marcos; Martínez, Jesús; Padilla, Pablo; Valenzuela-Valdés, Juan Francisco (2018-07-16)The power consumption foreseen for 5G networks is expected to be substantially greater than that of 4G systems, mainly because of the ultra-dense deployments required to meet the upcoming traffic demands. This paper deals ... -
A Capacity-enhanced local search for the 5G cell switch-off problem
Luna, Francisco; Zapata Cano, Pablo Helio; Palomares-Caballero, Ángel; Valenzuela Valdés, Juan F. (2020-03-06)Network densification with deployments of many small base stations (SBSs) is a key enabler technology for the fifth generation (5G) cellular networks, and it is also clearly in conflict with one of the target design ... -
Elementary landscape decomposition of the frequency assignment problem
Chicano, Francisco; Whitley, L. Darrell; Alba-Torres, Enrique; Luna, Francisco (2014-09-30)The Frequency Assignment Problem (FAP) is an important problem that arises in the design of radio networks, when a channel has to be assigned to each transceiver of the network. This problem is a generalization of the graph ... -

Optimización robusta de carteras de inversión usando muestreo estocástico y metaheurísticas
Luna, Francisco; Quintana, David; García, Sandra; Isasi, Pedro (2016-09-20)La optimización de carteras de inversión presenta un gran número de dificultades, siendo una de las más importantes la gestión de la incertidumbre que surge en diferentes aspectos del proceso. Este trabajo propone matizar ... -
Phase Shifter for Millimeter-Wave Frequency Range Based on Glide Symmetric Structures
Palomares-Caballero, Ángel; Alex-Amor, Antonio; Valenzuela-Valdés, Juan; Luna, Francisco; Padilla, Pablo (2019-03-13)The use of glide symmetry in radiofrequency devices to introduce dispersive effects has been recently proposed and demonstrated. One of these effects is to control the propagation constant of the structure. Here, we propose ... -
