The problem investigated in this work integrates a three-dimensional bin packing problem and a mode selection problem in the international consolidation context. Our objective is to minimize the total costs involved in the global supply chain, including ocean container costs, handling costs, Truckload (TL) and Less-than-truck (LTL) costs. Ocean container costs are the costs of shipping containers from China to US. Handling costs are incurred during unloading/loading shipments from containers onto the trucks. Inland transportation costs consist of both TL costs and LTL costs. The TL mode is often preferable if the shipments to the same destination are heavy or big. Otherwise, it may be more economical to choose LTL for delivery. The decisions to be made for this problem include: (1) the number of ocean containers used, (2) the assignment of multi-commodities to the ocean containers, and (3) the TL and LTL mode selection for final deliveries.
