| Summary | Published in April 2004 IOT SERIAL No. 93-56-790, 116pp. This paper aims at studying the suitable operation scale number of berths in container terminal by adopting Performance Indicator (AWT/AST equals 20% and AWT/AST=30%, respectively) on the basis of queuing theory and on the IND indicator that comprises ship cost, cargo cost, construction cost and crane procurements and etc. Then the variance of berth occupancy, variance ratio of berth occupancy, berth capacity difference, number of ships served, savings of cargoes, etc., are calculated to determine the operation performance of expanding the number of berths. The results reveal that the expansion from one-berth scale to two-berth scale reflects the largest benefit of operation performance. The expansion from two-berth scale to three-berth scale shows the second largest benefit of operation performance. The turning point occurs at the expansion from three berths to four berths situation. If the number of berths in the terminal is over six or seven, the benefits of berth expansion would become more stable, and the variance of indicators comes to insignificant. In other words, the container terminal will reach the economic scale of operation when there are no fewer than seven berths in the terminal. The results based on performance indicator and the IND indicators are similar. |
