A problem formulation for optimal mixed-sized box packing

Abstract In this paper, an approach for optimal mixed-size box packing is presented. The problem manages the packing of mixed-sized rectangular boxes to achieve optimal three-dimensional unit allocation in a limited space. Allocation of boxes of mixed size enables load plans for both multi-product and single-product problems. The problem formulation presented is a further extension of previous formulations applied on twodimensional Facility Layout and two and three-dimensional Process Plant Layout problems.
