Digital Twin + Industrial Internet for Smart Manufacturing: A Case Study in the Steel Industry business context would be sent back to the real-world object to be executed. I NDUSTRIAL I NTERNET P LATFORM AS AN I NDUSTRIAL D ATA O PERATING S YSTEM With a digital twin, therefore, we can describe, simulate and predict the state and behavior of its real-world counterpart based on analytics on historical and real-time data—and we can consequently optimally respond to changing conditions of the real- world counterpart. An industrial internet platform that is built with the latest advanced technologies— including Cloud Computing, Big Data and machine learning/Artificial Intelligence— offers great potential to rethink traditional digital architecture in the manufacturing environment, find new ways to bridge the application islands and channel data silos as described previously, enable holistic data- driven optimization across manufacturing applications and processes and more importantly enable a new breed of data- driven smart industrial applications. Furthermore, if we define a common construct (data, models and service API) for digital twins, we can build digital twins for components and from them construct digital twins for equipment, production lines, workshops, factories and even enterprises— just like we construct these entities in the real world. Digital twin thus offers a systematic approach to represent complex real-world systems—including those in the manufacturing environment and digital space—building comprehensive digital factories, as depicted in Figure 5. For example, cloud computing technologies built on the foundation of virtualization— including containerization and dynamic workload orchestration technologies— enable large-scale computation capabilities on demand with unprecedented scalability, Figure 5: Digital Factory Representation built from Digital Twin IIC Journal of Innovation - 17 -
