Supporting Circularity Strategies by Integrating Sustainability Aspects in SysML Models

Implementing sustainable and circular strategies for smart products requires consistent improvement of transparency and traceability over the entire product lifecycle. The early stages of product development play a critical role in the effective integration of sustainability strategies, as decisions made during this phase significantly influence the environmental performance throughout the product lifecycle. However, a consistent and direct assignment to system elements is a significant challenge. However, sustainability strategies such as reuse, remanufacturing, or reconfiguration require detailed models of (sub-)systems. To address these challenges, this paper focuses on a modeling approach that uses the Systems Modeling Language (SysML) v2 to model sustainability aspects at an early stage and links them to generic SysML v2 parts. For the instantiation, these generic blocks are linked to a complete set of system elements using the example of a 3D printer.
