A three-dimensional pallet loading method for single-size boxes

The problem of finding an optimal loading layout for packing identical boxes onto a rectangular loading pallet is known as the pallet loading problem. If the boxes may be stacked on their bottom, side, or end surface, the cube utilization of a pallet will increase, but the stability of the unit load will be lost sometimes. This paper presents a method that packs rectangular boxes of the same size onto a pallet. Incorporating certain practical considerations, the method consists of five phases that maximize the degree of stability and the maximum cube utilization of a unit load.
