This paper analyzed the use of combinable containers which can be de/coupled and used as a 20ft and 40ft size container. Based on a model by [6], our model considered a geographical factor in a trade zone with the huge hinterland. The experimental result showed that the ratio of combinable in use was higher among all the container types for distant owners to facilitate an efficient use of a whole container fleet to minimize the transportation cost.
