This paper presents applications of an optimization model to solve problems of arranging products (packed in boxes) on pallets, and arranging pallets on trucks. Different results are presented by solving thousands of randomly generated examples on a microcomputer. The methodology is applied to three case studies: two food industry distribution centers and one large wholesale distribution center. The use of the methodology to define optimal sizes of packages, pallets and trucks is also discussed. In particular, the performance of the Brazilian standard pallet (PBR), adopted by the Associação Brasileira de Supermercados (ABRAS), in comparison with other pallet types, is analyzed. Examining not only the loading of products on pallets, but also the loading of pallets on trucks, global utilization indices, which are useful to evaluate the economical performance of unit load systems in the logistic chain of a company, are obtained.
