Comparing the Efficiency of Two Types of Yard Layout in Container Terminals

Traditional container terminals usually use a horizontal yard layout, while automated vertical layout. The two types of layout perform differently in the vehicle travel routes, handling interface points vehicles and cranes, cranes routes. These differences result different indicators between such as utilization, average crane distance, overall terminal efficiency etc. This paper uses an analytic method to quantify these Based on analysis results, is approximated by queuing network from operations. In experiment studies, we first evaluate respectively. Then, change length width compare various sizes. Finally, compared. Results show that significantly affected service rate cranes. results this may provide references for design.
