A Parameter-free approach for solving combinatorial optimization problems through biased randomization of efficient heuristics
Ionescu, Dragos; Juan Pérez, Angel Alejandro; Faulín, Javier; Ferrer Biosca, Alberto (2011-01)
Article
Open AccessThis paper discusses the use of probabilistic or randomized algorithms for solving combinatorial optimization problems. Our approach employs non-uniform probability distributions to add a biased random behavior to classical ... -
A simulation-based algorithm for solving the Vehicle Routing Problem with Stochastic Demands
Juan Pérez, Angel Alejandro; Faulín, Javier; Caceres Cruz, Jose de Jesus; Riera Terrén, Daniel; Grasman, Scott (2011)
Conference report
Open AccessThis paper proposes a flexible solution methodology for solving the Vehicle Routing Problem with Stochastic Demands (VRPSD). The logic behind this methodology is to transform the issue of solving a given VRPSD instance ... -
Applications of discrete-event simulation to reliability and availability assesment in civil engineering structures
Juan Pérez, Angel Alejandro; Monteforte, A.; Ferrer Biosca, Alberto; Serrat Piè, Carles; Faulín, Javier (2009)
Conference report
Open AccessThis paper discusses the convenience of predicting, quantitatively, time-dependent reliability and availability levels asso-ciated with most building or civil engineering structures. Then, the paper reviews different ... -
Combining biased randomization with meta-heuristics for solving the multi-depot vehicle routing problem
Juan Pérez, Angel Alejandro; Barrios, Barry; González Martín, Sergio; Coccola, Mariana; Faulín, Javier; Bektas, Tolga (2012)
Conference lecture
Restricted access - publisher's policyThis paper proposes a hybrid algorithm, combining Biased-Randomized (BR) processes with an Iterated Local Search (ILS) meta-heuristic, to solve the Multi-Depot Vehicle Routing Problem (MDVRP). Our approach assumes a ... -
Combining Monte-Carlo simulation with heuristics for solving the inventory routing problem with stochastic demands
Cáceres Cruz, José; Juan Pérez, Angel Alejandro; Bektas, Tolga; Grasman, Scott; Faulín, Javier (2012)
Conference lecture
Restricted access - publisher's policyIn this paper, we introduce a simulation-based algorithm for solving the single-period Inventory Routing Problem (IRP) with stochastic demands. Our approach, which combines simulation with heuristics, considers different ... -
On the use of Monte Carlo simulation, cache and splitting techniques to improve the clarke and wright savings heuristics
Juan Pérez, Angel Alejandro; Faulín, Javier; Jorba, Josep; Riera, D; Masip Rodó, David; Barrios, Barry (2011)
Article
Restricted access - publisher's policyThis paper presents the SR-GCWS-CS probabilistic algorithm that combines Monte Carlo simulation with splitting techniques and the Clarke and Wright savings heuristic to find competitive quasi-optimal solutions to the ... -
Simulation education in the internet age: some experiences on the use of pure online and blended learning models
Fonseca Casas, Pau; Juan Pérez, Angel Alejandro; Pla, Lluis M.; Rodríguez, Sara V.; Faulín, Javier (2009-12-13)
Conference report
Open AccessIn this paper we analyze several cases related to three different Spanish universities that make use of the World Wide Web to teach simulation courses online. These universities are the Open University of Catalonia, the ... -
Structural reliability and availability analysis through simulation
Juan Pérez, Angel Alejandro; Simosa, Jorge; Faulín, Javier; Monteforte, Arai; Guo, Harry (2011)
Article
Open AccessIn this paper, some potential applications of simulation in structural reliability and availability are presented. Unlike the analytical methods, where assumptions that simplify complex analysis often need to be made, ... -
Using discrete-event simulation to design reliable and cost-efficient civil engineering structures
Juan Pérez, Angel Alejandro; Ferrer Biosca, Alberto; Serrat Piè, Carles; Faulín, Javier; Hester, J.; López Brosa, Pere (2009-09)
Conference report
Open AccessIn this paper the topic of Structural Reliability Analysis and its importance in modern Civil Engineering is introduced. Throughout the paper, some advantages that simulation-based approaches offer with respect to other ... -
Using parallel & distributed computing for solving real-time vehicle routing problems with stochastic demands
