In the field of e-commerce warehousing, maximizing utilization packing bins is a fundamental goal for all major logistics enterprises. However, determining appropriate size poses practical challenge many companies. Given limited research on open-size 3D bin problem as well high complexity and lengthy computation time existing models, this study focuses optimizing multiple-bin sizes within context. Building upon research, we propose hybrid integer programming model, denoted three dimensional multiple option rectangular (3D-MODRPP), to address problem. Additionally, leverage well-established hardware software technologies system capable accommodating types with open dimensions. To reduce model number constraints, introduce novel assumption method 0–1 variables in overlap rotation constraints. By applying approach, significantly streamline computational associated calculations. Furthermore, refine dataset by developing customized version based classical Three-Dimensional One-Size Dependent Rectangular Packing Problem (3D-ODRPP) dataset, leading improved outcomes. Through comprehensive analysis results, our exhibits remarkable advancements addressing strong heterogeneous problem, weak actual sizes. Specifically, it reduces increases space utilization. The designed paves way applications proposed providing researchers broader prospects directions expand scope investigation packing.
