The purpose of this study was to evaluate current packaging modules and design the most acceptable packaging module for domestic and international distribution systems. An optimum packaging module can reduce package costs as well as total distribution costs such as transport, materials handling and warehouse costs. Three different sizes of packaging modules, namely U-type(600 × 500 mm), K -ype(550 × 366 mm) and I-type(600 × 400 mm), were evaluated in terms of the area efficiency and MOEs(measures of effectiveness) for the T-11(1100 ×1100mm ) and T-12(1,200 × 1,000 mm) pallets. The results showed that the U-type module could fit very well for both pallets and the area efficiency of each module was more than 99 percents. Area efficiency of K-and I-type modules was greatly affected by the pallet footprint dimensions. U-type module also performed better result from MOEs evaluation. Twenty sub-multiple sizes derived from the U-type module were suggested for the future development of the Korean and ISO standards on dimension of transport packages.
