Text en actes de congrés
Accés obertAmong the human-being problems, there are those which carry with the exploration of a number of feasible and unfeasible possible solutions. These have been a challenge faced constructing specific strategies. Thus, techniques ... -
SR-1: A simulation-based algorithm for the capacitated vehicle routing problem
(ISI Proceedings, 2008-12)
Capítol de llibre
Accés obertIn this paper we present SR-1, a simulation-based heuristic algorithm for the capacitated vehicle routing oroblem (CVRP). Given a CVRP instance, SR-1 uses an initial “good solution”, such as the one provided by the classical ... -
Structural reliability and availability analysis through simulation
(2011)
Article
Accés obertIn 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, ... -
