  • This paper analyzed productivity of quay cranes on container terminal that have perpendicular yard layout block. In most existing container terminals, quay cranes of single trolley type are used to loading and unloading containers, but quay crane productivity of these type has many limitation about large size containership. For these reasons, recently quay cranes of various type that mn improve productivity are developed and as the representative example, dual trolley, double trolley, supertainer are developing. These cranes are realized that very high productivity bemuse their cycle time is short more than existent single trolley quay crane. Therefore, we analyzed productivity of these cranes that are realized by next generation crane alternatives and as result qf this research, mechaniml productivity by cycle time and net productivity by simulation were measured.

  • The purpose of this paper is to evaluate the quay crane productivity in automated container terminal with perpendicular yard layout. In particular, four quay crane (single trolley/dual trolley/double trolley/supertainer) are considered to evaluate the productivity on the terminal performance. Each quay crane load or unload containers by a different process. For each quay crane, two productivities are considered and compared: mechanical productivity, net productivity. As the net productivity of quay crane is significant, in this paper, an application of simulation model to simulate automated container terminal is developed and a wide variety of computational experiments were conducted.
