Closed loops depict supply chains for which Original Equipement Manufacturer reintegrate their returned products into their own production network. While the reverse logistics research has extensively addressed the technical aspects of product reintegration, very few insights are available on whether OEMs should commit themselves to a closed-loop. The structure of the monograph is aligned to the decision-making process of Original Equipment Manufacturers willing to investigate the potential of closed-loops.
