Knowledge Base Repository

In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
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.
