A biased-randomized learnheuristic for solving the team orienteering problem with dynamic rewards
Reyes-Rubiano, Lorena Silvana
; Juan Pérez, Ángel Alejandro; Bayliss, C.; Panadero, Javier; Faulín Fajardo, Javier ; Copado, P. (Elsevier, 2020)
Contribución a congreso / Biltzarrerako ekarpena 
In this paper we discuss the team orienteering problem (TOP) with dynamic inputs. In the static version of the TOP, a fixed reward is obtained after visiting each node. Hence, given a limited fleet of vehicles and a threshold ... -
Cooperación horizontal en problemas de rutas de vehículos con retornos
Belloso Ezcurra, Javier (2017)
Tesis doctoral / Doktoretza tesia
En el mundo competitivo y global en que se desarrollan las actividades de las empresas, las prácticas de cooperación entre entidades distintas suponen una gran oportunidad para aumentar la eficiencia en las operaciones. ... -
Electric vehicles in logistics and transportation: a survey on emerging environmental, strategic, and operational challenges
Juan Pérez, Ángel Alejandro; Méndez, Carlos Alberto; Faulín Fajardo, Javier ; Armas, Jesica de; Grasman, Scott Erwin (MDPI, 2016)
Artículo / Artikulua
Current logistics and transportation (L&T) systems include heterogeneous fleets consisting of common internal combustion engine vehicles as well as other types of vehicles using “green” technologies, e.g., plug-in ... -
Horizontal collaboration in freight transport: concepts, benefits and environmental challenges
Serrano Hernández, Adrián ; Juan Pérez, Ángel Alejandro; Faulín Fajardo, Javier ; Pérez Bernabeu, Elena (Institut d'Estadística de Catalunya, 2017)
Artículo / Artikulua
Since its appearance in the 1990s, horizontal collaboration (HC) practices have revealed them-selves as catalyzers for optimizing the distribution of goods in freight transport logistics. After introducing the main concepts ... -
An inventory-routing problem with stochastic demand and stock-out: a solution and risk analysis using simheuristics
(IEEE, 2019) Contribución a congreso / Biltzarrerako ekarpena
Supply chain operations have become more complex. Hence, in order to optimise supply chain operations, we often need to simplify the optimisation problem in such a way that it can be solved efficiently using either exact ... -
On the use of biased-randomized algorithms for solving non-smooth optimization problems
Juan Pérez, Ángel Alejandro; Corlu, Canan Gunes; Tordecilla, Rafael D.; Torre, Rocío de la ; Ferrer, Albert (MDPI, 2020)
Artículo / Artikulua
Soft constraints are quite common in real-life applications. For example, in freight transportation, the fleet size can be enlarged by outsourcing part of the distribution service and some deliveries to customers can be ... -
Optimizing energy consumption in transportation: literature review, insights, and research opportunities
Corlu, Canan Gunes; Torre, Rocío de la ; Serrano Hernández, Adrián ; Juan Pérez, Ángel Alejandro; Faulín Fajardo, Javier (MDPI, 2020)
Artículo / Artikulua
From airplanes to electric vehicles and trains, modern transportation systems require large quantities of energy. These vast amounts of energy have to be produced somewhere—ideally by using sustainable sources—and then ... -
A review of simheuristics: extending metaheuristics to deal with stochastic combinatorial optimization problems
Juan Pérez, Ángel Alejandro; Faulín Fajardo, Javier ; Grasman, Scott Erwin ; Rabe, Markus; Figueira, Gonçalo (Elsevier Ltd., 2015)
Artículo / Artikulua
Many combinatorial optimization problems (COPs) encountered in real-world logistics, transportation, production, healthcare, financial, telecommunication, and computing applications are NP-hard in nature. These real-life ... -
Simheuristic algorithms for the sustainable freight transport problem
Reyes-Rubiano, Lorena Silvana (2019)
Tesis doctoral / Doktoretza tesia
The sustainable freight transport entails the design of the distribution plans with the least negative impacts. On one hand, this distribution problem relies on deter-mining the routes to visit a set of customers, which ... -
A simheuristic for routing electric vehicles with limited driving ranges and stochastic travel times
Reyes-Rubiano, Lorena Silvana ; Ferone, Daniele; Juan Pérez, Ángel Alejandro; Faulín Fajardo, Javier (Institut d'Estadistica de Catalunya (Idescat), 2019)
Artículo / Artikulua
Green transportation is becoming relevant in the context of smart cities, where the use of electric vehicles represents a promising strategy to support sustainability policies. However the use of electric vehicles shows ... -
Using modelling techniques to analyze urban freight distribution. A case study in Pamplona (Spain)
Álvarez, Pablo ; Serrano Hernández, Adrián ; Faulín Fajardo, Javier ; Juan Pérez, Ángel Alejandro (Elsevier, 2018)
Contribución a congreso / Biltzarrerako ekarpena
The city of Pamplona, in Spain, is currently experiencing several changes regarding sustainable mobility such as pedestrianization of some streets in the city center, and access control to the Old Town for motor vehicles ...
