Cross-Generational Remanufacturing: Identifying high-potential subsystems through differential analysis of product generations

A critical factor for implementation of the recently developed concept of Cross-Generational Remanufacturing (CG-Reman) – i.e., integrating remanufactured subsystems into new products of the latest product generation for the primary market in a planned and anticipated industrial process – is determining which subsystems of a focal product should be considered prioritized in targeted “Design for CG-Reman” efforts. As one method to identify such potential, we propose the method of a differential analysis, which identifies promising subsystems by assessing the extent, relevance, and baseline impact of each observed change between product generations. Based on empirical studies of two product generations of a kitchen appliance, we developed a framework for conducting such differential analysis along with suitable evaluation criteria. The analysis supports a systematic and applicable assessment of CG-Reman potential and thereby the directed application of CG-Reman.
