Abstract
The objective of this paper is to analyze the combined productivity of stevedoring system at port container terminal. In general, the productivity of container terminal is evaluated by the productivity of container cranes at apron, but there are other equipments such as transport vehicles and yard cranes. Therefore, a method that can estimate the optimal equipment combination of stevedoring system in container terminal is proposed. From the application of the case study, we demonstrated the savings effect using mean waiting time rates by the equipment combinations. We performed various simulation experiments and estimated the equipment combinations to increase the productivity and to decrease the waiting time between equipments. From the results of the simulation analysis, we demonstrated that bottleneck occurs in TC (Transfer Crane) including TC waiting and waiting of YT(Yard Tractor) in front of TC. In order to improve the combined productivity and decrease savings effect, the equipment should be change from 10 TCs to 12 TCs.
