Enhancing Production Planning and Control by Integrating the Circular Strategy ‘Repair’
摘要
Production planning and control (PPC) is a central task for manufacturing companies to align the logistical performance of production to customer requirements. Alongside well-established customer requirements such as delivery time and quality, sustainability-related criteria are gaining importance for maintaining competitiveness. In response, many manufacturing companies are increasingly adopting circular economy principles, also known as circular strategies. A promising approach to integrate circular strategies into production processes is the ‘repair’ strategy, in which end-of-life products are restored to full functionality to extend their lifespan. However, due to fluctuations in the availability and quality of end-of-life products, the resulting interactions with existing processes lead to new challenges for PPC. Despite repair’s increasing role in circular production systems, its specific impact on PPC and related interdependencies remains unexplored. For this reason, the present paper deals with the systematic identification and deductive derivation of resulting interdependencies within PPC that emerge from integrating the ‘repair’ strategy and embeds these findings within an existing PPC framework model. Ultimately, this paper contributes to a deeper understanding of how repair as a circular strategy affects PPC processes and provides a foundation for future framework development in this research area.
