Fast and efficient container ships are continually being built. For these ships to earn a profit, their port turnaround time must be kept to a minimum. Delays in port time can easily destroy economic gains earned by fast efficient voyages. This study presents a computer program which simulates the loading and unloading operations of a container ship. The interaction between the ship and the terminal along with the variations in ship displacement, stability, trim, and heel are monitored during the simulation. The simulated system consists of a container ship, containers, container handling vehicles, a container terminal yard, and a dockside crane. The physical constraints of the system are established by the user. The computer language used in this program was IBM's General Purpose Simulation System (GPSS). The mathematical modeling of a general container handling system was emphasized in the program. However, the practical application of such a model was always considered. This program is an initial step toward optimizing the various components which constitute a profitable marine transportation system. The programming method and various comparative results are of immediate technical interest. Naval architects must consider such a system if they are to improve marine transportation. /Author/
