An Industry 4.0-Compliant Digital Product Passport Approach for Realising Dairy Product Traceability

This paper provides an approach to create the digital thread associated to the value stream along a dairy process value chain. Identifying the different stakeholders within the dairy process, each of them is concretely positioned as provider of assets to be digitalized and networked using the Asset Administration Shell technology and this within an Eco-system formally specified by the 3D-Reference Architecture Model for Industry 4.0 (RAMI 4.0). The different sub-models of the Asset Administration Shells along the digital thread are then an essential part of the so called Digital Passport, which will be associated to different dairy products (milk powders, butter, whey, cheese, etc.). The Digital Passport is the core tool allowing all stakeholders for performing traceability of products and processes. It provides digitalized data and information, to be exposed and/or consumed as services, developed and shared in real-time by all the actors of the dairy supply chain, responding to strict dairy process business requirements.
