It was calculated each P.D.C. of 15 items added physically and directly to the container cargoes during processing from vanning to shipping by the productive implements and labor efficiency. The laborers' working hours and wages were fixed at present and some schemes and problems for the rationalization of container system were investigated parameterically. The results are reported as follows: 1. The container transportation form using the trailers shoud be planned variously before the curtailment of the drivers' number. 2. Compared the researched quantity of operating cargoes with the number of container berths being planned in Japan, the excess of supply about the number is considered. 3. The lower P.D.C. of the road, straddle carrier and labourers in port hinders lowering the total P.D.C. 4. The most suitable scheme of the container transportation is to balance each P.D.C. added to cargoes by the processing parts.
