Arellano Arriaga, Nancy Aracely; Molina-Luque, Julián
; Schaeffer, Satu-Elisa; Álvarez-Socarrás, Ada-Margarita; Martínez-Salazar, Iris-Abril (Springer, 2019)
We study a bi-objective problem called the Minimum Latency-Distance Problem (mldp) that aims to minimise travel time and latency of a single-vehicle tour designed to serve a set of client requests. This tour is a Hamiltonian ... -
A Class of Indices and a Graphical Tool to Monitor Temperature Anomalies
Hueso-González, Paloma; Ruiz-Sinoga, José Damián; Bárcena-Martín, Elena María; Molina-Luque, Julián (SAGE journal, 2020-02-26)
We propose a graphical device—Three I’s of Anomalies (TIA) curves—that provides information on the incidence, intensity, and inequality (variability) of air temperature anomalies. We also propose a class of indices that ... -

Modeling the social-spatial structure of urban spaces can facilitate the development of guidelines aimed at curbing the spread of the COVID-19 pandemic while also acting as an instrument that helps decision-making concerning ... -
Issues and challenges in defining a heat wave: A Mediterranean case study
Bárcena-Martín, Elena María; Molina-Luque, Julián; Ruiz-Sinoga, José Damián (Royal Meteorological Society, 2019)
We evaluated three definitions of heat wave (HW) and demonstrate that selection of the reference period and air temperature threshold used in the definition can affect the reported frequency of HWs. First, we propose an ... -
Learning about the incidence and lethality of COVID-19 in vulnerable neighborhoods: The case of Malaga (Spain).
This research delves into the need to use granular analyses at the neighborhood level to study the preexisting conditions of vulnerability that best explain the waves of COVID- 19 incidence and mortality. It seems most ... -
Modeling the Rainfall Exploitation of the Reservoirs in Malaga Province, Spain
In areas with scarce water resources, it is so important to analyze the connection between the different elements of a river basin and the water collected by the basin’s reservoir, to determine and predict the spatial and ... -
Optimizing a bi-objective vehicle routing problem that appears in industrial enterprises
López-Sánchez, Ana D.; Molina-Luque, Julián; Laguna, Manuel; Hernández-Díaz, Alfredo G. (Wiley Online Library, 2021)
In this paper, a new solution method is implemented to solve a bi- objective variant of the Vehicle Routing Problem that appears in industry and environmental enterprises. The solution involves designing a set of routes ... -
