Abstract
The shipping industry is a crucial part of the national industry, interested in efficiently managing the operation of ships and ports to increase national competitiveness. The smart port industry is a topic of international interest, and we want to apply digital twins to make it a reality. A digital twin implements a real-world object in a virtual environment, significantly reducing costs and risks when used in operational experiments on ships and terminals. The Busan New Port Container Terminal was implemented as a digital twin, considering the waiting cost in the port of the ship, the terminal operation cost to handle the container, and the towing cost incurred when the ship is berthing. The efficiency of the berth plan was improved by comparing the berth plan before and after digital twin application for June 2021 of the PNIT Pier of Busan New Port. This study provided additional tugboat planning to the berth plan, increased the berth layout productivity, shortened the update cycle compared with the existing berth plan, and developed a long-term berth plan. Future studies are expected to optimize the scheduling of autonomous ships and ports.
