An efficient method for the three-dimensional container loading problem by forming box sizes

This study focuses on a real-world case that is defined as an extension of the container loading problem (CLP) with weakly heterogeneous types boxes. A company producing plastic cups wants to increase its efficiency in operations. To solve problem, hybrid approach including static rule rank orders and integer nonlinear programming (INLP) models developed. INLP form box sizes according properties cups, determine position boxes layers while simultaneously minimizing layer-depth. The presented tested cases benchmark data sets. results show forming solving CLP increases effectiveness
