Digital Twin Modeling Method for Container Terminal in Port

Abstract

With the acceleration of the construction of smart ports, the business process in ports is becoming more and more intelligent. Most container terminals in port are generally more automated than other terminals, so it is easier to promote the informatization construction of automated terminals. Through digital twin technology, a container terminal in port can be simulated into a complete system with different combinations of layout, equipment and technology, which can realize real-time monitoring, optimize business processes and bring huge economic benefits. In short, digital twin technology has become an important factor in promoting the development of container terminal. In this paper, digital twin technology is applied to the business of container terminal. Meanwhile, the business processes of container terminal are sorted out according to production factors, production information and production tasks. Then a digital twin model modeling method for container terminal from the three dimensions of element, behavior and rule is proposed to realize the virtual simulation of container terminal. The modeling process of element model, behavior model and rule model in port is elaborated in detail. Taking the container terminal in Qingdao Port as a case study, a digital twin system architecture of container terminal is studied. Part of the DT modeling process of container terminal in Qingdao Port is provided. The feasibility and effectiveness of the modeling method are verified. At last, some applications of digital twin container terminal are advised.
