| abstract | Efficient operation of a closed-loop supply chain should be supported by reasonably good forward and reverse processes. However there exists the chronic problem of uncertainty about returned end-of-life products with regard to timing, quality and quantity, which hinders the efficient operation of closed-loop supply chain. The problems could be solved if we have visibility of physical flow of returned products and its quality by using the Internet-of-Things (IoT) technology. It enables information sharing among all entities in the supply chain and enables us to grasp the actual condition of the returned products accurately. Also information visibility gives chance to improve the process for disassembly and product disposition to minimize cost of the total system. First, we develop a mathematical model of a closed-loop supply chain within the IoT-based information sharing environment consisting of a supplier, a manufacturer, and a reprocessing facility in 3 different markets, namely new products, remanufactured and spare parts. Next we address a multi-period production planning model for multiple products consisting of multiple components with the objective of minimizing the sum of all incurred costs from the standpoint of a manufacturer. We also analyze the behavioral characteristics of the model and conduct experiments to justify the proposed scheme. |
