- Reference Architecture for Sustainable Manufacturing -as-a-Service driven by Digital TwinPublication . Neto, Diogo Alves Machado; Sousa, Cristóvão Dinis Polido de; Pereira, Carla Sofia GonçalvesThe industrial paradigm is shifting towards a data-driven Circular Economy, a transition hindered by a fragmented digital landscape of data silos. Regulatory drivers, such as the European Union’s Digital Product Passport, are transforming standardized and sovereign data sharing into a legal necessity, creating an urgent need for a cohesive solution. This thesis addresses the lack of a holistic architectural framework for industrial data sharing by proposing a reference architecture for the Internet of Digital Twins. Following a Design Science Research methodology, this work presents a Reference Architectural Model for Industry 4.0-compliant blueprint that cohesively integrates key standards for data modeling, sovereign data sharing infrastructure, and a decentralized cryptographic trust layer. The architecture’s viability is validated through a two-part experimental approach. First, a Proof of Concept demonstrates the technical feasibility of one of the architecture’s layers by automating the aggregation and standardization of data from both Operational Technology and Information Technology sources. Second, a scenario-based Proof of Value argues for the utility of the full architecture in enabling complex, sustainable manufacturing applications. The primary contribution of this work is, therefore, a validated and prescriptive blueprint for building the secure, interoperable, and trustworthy data ecosystems required for the data-driven circular economy.
