IMPROVEMENT OF SHIPBERTH CAPACITY FOR A CONTAINER PORT

This paper presents a proposal of optimization of ship berth capacity for container port. Many aspects need to be taken into account in the process of optimization, which are waiting time, productivity of port, number of berth in port, and various sizes of container ships.  The efficiency of a port depends on the speed of cargo handling. In this study, mathematical model had been derived to determine the required quay or wharf for a new port.  The mathematical model can also be used to determine the required number of cranes in an existing port to maintain a good average waiting time. In order to determine the required number of quay, six elements had been considered in the equation of the mathematical model.  The elements are arrival rate, overall length of ships, berthing time, number of operating cranes, average waiting time, and crane rates.  Every single element is a dependent mode and inter-related to one another. The mathematical model was modelled using MATLAB, with twenty sample data, by simulation method. The findings were then compared to those of other researchers who had attempted to solve the problem using queuing theory and simple mathematical analysis. The results showed that the simulation is 85 percent more effective in determining the efficiency of a port based on the provided parameters. The main objectives were achieved, signifying that the sharing of cranes with adjacent berth is mainly used to maintain cargo handling rates at port.
