Las empresas de distribución tiene que decidir cómo cargar los productos en los camiones y determinar su ruta. Los productos se empaquetan en pallet, colocando los pallets de cada cliente juntos, en el camión.
La demanda de un cliente puede exceder la capacidad del camión permitiendo dividir la entrega de un cliente en varios camiones. Cada camión puede cargar un peso máximo y hay un límite en el peso de cada eje. La carga debe ser estable, para evitar movimientos. Todas estas restricciones de ruta y embalaje se incluyen en un modelo lineal entero cuyo objetivo es minimizar la distancia total de viaje.
Presentamos un extenso estudio computacional que muestra el rendimiento y los límites del modelo propuesto. Proponemos un algoritmo de descomposición en el que algunas de las restricciones de empaquetamiento se relajan, luego son consideradas por un algoritmo heurístico. Si la heurística falla, se utiliza un modelo auxiliar para asegurar la optimalidad de la solución obtenida.
