Bidirectional Integration of Digital Product Passports into Information Systems of Production Planning and Control

Circular economy (CE) is considered to be the business model of the future, since it enables decoupling of economic growth and resource consumption. Digitalization is an enabler for companies to accomplish the transition to circular business models, as it enables automated data sharing and usage, but it also poses an enormous challenge. The data required for the implementation of circular business models is generated during the entire life cycle of a product. Digital product passports (DPP) represent a solution for the exchange of product-related data across the entire life cycle and various stakeholders. So far, they have hardly been integrated into production planning and control (PPC) systems. This paper describes requirements, specific use cases and related data flows for an integration of DPP and PPC systems. Finally, a model is presented that enables event-driven creation and use of data for the bidirectional integration of DPP into PPC systems.
