The purpose of this study is to optimize the total physical distribution system, and so the authors built the system model of inland to port transportation of exporting general cargo, which consists of 7 inland routes combined with road, railway, barge transportation and warehouse. And the physical distribution costs were calculated through computer simulation. The results of study, which should be managed for the sake of reducing the P.D.C., were as follows: (1) There is the optimum combination of elements affected on P.D.C. to handle the cargo flow efficiently. (2) The percentage of port facility's cost against total P.D.C. is 56.4〜37.7 and ship's cost is 41.5〜9.4. So the P.D.C. is influenced extremely by these two elements of cost. (3) The ratio of cargo via apron should be increased together with simplification of inland route. (4) The utilization factor of berth should be kept between 0.60 and 0.88.
