Overview
IEC/TR 63319:2025 - A Meta-modelling Analysis Approach to Smart Manufacturing Reference Models provides a high-level analysis of ten prominent smart manufacturing reference models. Issued by ISO and IEC, this technical report adopts a meta-modelling framework to identify and compare the common and unique features of each model within the smart manufacturing domain. The document aims to guide the development of a unified reference model that can serve as the cornerstone for digital transformation and Industry 4.0 initiatives, facilitating smarter, more connected, and highly automated manufacturing environments.
Key Topics
- Meta-modelling Methods: The report explains the meta-modelling approach, demonstrating how multiple levels of abstraction are used to analyze different smart manufacturing models. This includes transitions from high-level conceptual models to detailed domain and implementation models.
- Reference Model Comparison: Ten leading reference models are mapped and analyzed within consistent topic areas such as life cycle, hierarchy, and layers, highlighting both shared foundations and distinctive approaches.
- Core Smart Manufacturing Concepts: Essential principles such as the integration of information and communication technologies, system hierarchies, and the use of generic methods in manufacturing automation are explored.
- Key Model Features: Common aspects identified include manufacturing life cycles, layered architectures (for example, business, production, and IT layers), and hierarchical organization from the enterprise level to individual devices.
- Issues & Challenges: The report outlines existing challenges and areas requiring future research to achieve convergence toward a unified, high-level reference model that encompasses diverse industry needs.
Applications
The guidance and meta-analysis methodology documented in IEC/TR 63319:2025 can be applied in several areas:
- Reference Model Selection and Harmonization: Organizations can leverage the comparative insights to choose or harmonize appropriate smart manufacturing frameworks aligned with their digital transformation strategies.
- Model Development: System architects and standards developers benefit from the document’s abstraction stack and facet analysis, informing the creation of new or customized reference models.
- Implementation Planning: By understanding the mapping from conceptual models down to operational implementation, project teams can better plan the architecture and integration of smart manufacturing systems.
- Training and Knowledge Transfer: The comparative approach provides a solid basis for educational programs aimed at upskilling staff on smart manufacturing standards and best practices.
- Strategic Decision-Making: Enterprises, standards bodies, and technology providers can use the findings to inform investments, partnerships, and policy development in Industry 4.0 and digital manufacturing.
