An Object Process Modelling Ontology for a Digital Twin Prototype supporting Factory and Production Planning

In recent years, Digital Twin (DT) has emerged as a crucial technology for exploring dynamic behaviors related to Factory and Production Planning (FPP) within manufacturing companies. Despite its growing interest, literature lacks specific ontologies to establish a foundational conceptual DT prototype. To address this gap, this study proposes a structured set of concepts for DT prototype creation within the FPP context utilizing the Object Process Methodology, recognized as ISO 19450. The structured model integrates both physical and informatical nature of objects and processes in make-to-order companies to implement DT conceptual modelling. The conceptual model is assessed in a real-world industrial context with insights from industrial stakeholders.
