以产品为类直方体、外包装容器为瓦楞纸箱的托盘包装系统为研究对象，提出了能同时降低包装用料成本和仓储成本的瓦楞纸箱尺寸优化设计方法。介绍了优化设计方案，分别建立了瓦楞纸箱省料模型和托盘装载优化模型，从瓦楞纸箱设计、托盘装载、仓储空间各个环节进行优化，以提高托盘表面利用率和仓储空间利用率，降低包装成本，并给出了纸箱尺寸优化流程。

An optimal design method of corrugated box dimension was put forward to reduce the cost of packaging material and storage, in which the object of study is assumed by taking product as quasi-square and outer packaging container as corrugated box. The optimal design scheme was introduced, which was to establish material saving corrugated box model and optimized pallet load model and to carry out optimization in the processes of corrugated box design, pallet load, and storage space in turn to improve area utilization and cube utilization of pallet and reduce packaging cost. The optimization flowchart of corrugated box dimension was presented.
