A Data Model for the Steel Production

A data model for the steel production is presented, based loosely on ETSI’s SAREF4INMA standard. It models the production resources, such as steel billets, slabs or coils, production equipment, such as a continuous casting machine or a hot rolling mill, and is capable of representing the tracking uncertainty characteristic of the production of steel long products. A property graph representation of the involved entities is used, where not only each entity is typed, but also the links between entities. The model has been developed as part of a digital twin software platform in the CAPRI project and serves as documentation for the application programming interfaces. A decision support system for through-process quality control is being realised as the main application based on the platform.
