This paper proposes an approach to develop schedules for charging batteries in a battery center. This problem arises in warehouses and logistics centers that attempt to provide uninterrupted operations with battery powered ...

The present paper solves the multi-level capacitated lot sizing problem with backlogging (MLCLSPB) combining a genetic algorithm with the solution of mixed-integer programming models and the improvement heuristic fix and ...

The recent natural disasters around the world have shown the difficulties of the various organi- zations in effectively manage post-disaster operations. These difficulties reflect the complexity of ...

In air passenger transport, events often occur that make it impossible to comply with the flight schedule planned for a certain period. In these situations, the Aircraft Recovery Problem (ARP) emerges, which involves ...

The current work develops a MIP model for the planning of shipping and disembarking operations in a distribution centre that receives products from a production plant, auxiliary stores and foreign suppliers. The objective ...

We consider the capacitated lot sizing problem with multiple items, setup time and unrelated parallel machines. The aim of the article is to develop a Lagrangian heuristic to obtain good solutions to this problem and good ...
