Journal ArticleDOI
Bike sharing systems: Solving the static rebalancing problem
TL;DR: Efficient algorithms for solving instances of reasonable size and the possibility of using the information provided by the relaxation receives a special attention, both from a theoretical and a practical point of view are presented.
Journal ArticleDOI
Solving the Capacitated Location-Routing Problem by a Cooperative Lagrangean Relaxation-Granular Tabu Search Heuristic
TL;DR: A cooperative metaheuristic to solve the location-routing problem with capacitated routes and depots is presented and it is shown that this meta heuristic outperforms other methods on various kinds of instances.
Journal ArticleDOI
Solving the capacitated location-routing problem by a GRASP complemented by a learning process and a path relinking
TL;DR: A new metaheuristic to solve the LRP with capacitated routes and depots is presented, based on an extended and randomized version of Clarke and Wright algorithm and is competitive with a meta heuristics published for the case of uncapacitated depots.
Journal ArticleDOI
A Branch-and-Cut method for the Capacitated Location-Routing Problem
José-Manuel Belenguer,Enrique Benavent,Christian Prins,Caroline Prodhon,Roberto Wolfler Calvo +4 more
TL;DR: Two formulations of the location-routing problem with capacities on routes and depots are presented and an exact method based on a branch and cut approach is proposed using these formulations.
Journal ArticleDOI
An effective memetic algorithm for the cumulative capacitated vehicle routing problem
TL;DR: This paper presents the first upper and lower bounding procedures for this new problem, the CCVRP, by a memetic algorithm using non-trivial evaluations of cost variations in the local search and good results are obtained.
