  11. 11. 2. Research goals Vision of the Project To create a sustainable and resilient world where remanufacturers and their closed-loop networks have ‘visibility’ of returns and reflect such information into circular economy compatible inventory and production control systems.
  12. 12. 14 2. Research goals Re R u N
  13. 13. 15 2. Research goals 1. We aim to explore how returns forecasting impacts on the dynamic performance of closed-loop supply chains. This entails considering a ‘two-tailed’ uncertainty problem (demand and returns), which has been barely picked up by academic research.
  14. 14. 16 2. Research goals 2. We aim to investigate how informatics (cyber-physics, IoT, Big Data) may contribute to a better understanding of closed- loop systems. No studies have been found to address what data are relevant to efficient inventory and production management and how such data and any insights uncovered can be interfaced with and then incorporated into solving the problem.
  15. 15. 17 2. Research goals No studies to-date look at how returns forecasting and the replenishment rules can be integrated in a systemic way to optimise inventory and production management. 3. . We aim to design a systemic solution based on the concept of holons, given the integrated nature of the supply chain. The solution must be resilient to uncertainties and disturbances, including the ‘two-tailed’ uncertainty.
  16. 16. 18 3. The Project Plan WP1: Empirical grounding of research • Aimed at identifying the streams of information through which uncertainty manifests itself and thus appreciate what forecasting approaches are most relevant and how current systems models can be appropriately expanded to capture uncertainty. WP2: Theory development and empirical testing • Aimed at developing new theory on returns forecasting and systems modelling in the presence of uncertainty, and assess such theoretical propositions (independently) for their empirical validity. WP3: ‘What if?’ analysis and integrated solution • Aimed at establishing a suite of archetype holons of forecasting and inventory & production control for remanufacturing and to ensure the practical relevance of our propositions. WP4: Dashboard for direct impact • Aimed at developing a dashboard for practical applications and being generic enough for wider exploitation by the remanufacturing sector.
