Evaluates a new hierarchical lifecycle model for effective circularity measures in product design, indicating potential resource efficiency improvements.
As companies face increasing accountability for resource efficiency, circularity measures like repair or remanufacture offer a promising solution. Modeling expected product lifecycles in early design phases is crucial for planning their effective application. This paper introduces a hierarchical lifecycle model to represent component-specific lifecycle paths across all product architecture levels in a single model. Our approach ensures consistency across hierarchy levels and facilitates precise application of component-specific circularity measures, promoting effective circular product design.
