説明

In this study we first present a decision approach for the optimal input quantity of new part in a remanufacturing system that considers product lifecycle (PLC)(Proposal 1). Next, we discuss the utility of a service network for the collection and disassembly (NCD) of reusable products with PLC or a part with PLC received from a customer or an internal production process, and present a decision approach for the optimal input quantity of a new part in a remanufacturing system that considers PLC (Proposal 2). In Proposal 2, it is assumed that by paying a commission fee to the NCD, both more used products and more defective units (parts or finished products) will be taken back more smoothly from the customer/each production process, disassembled more rapidly, and the parts will be reused as spare parts in each production process. It is expected that the remaining quantity of reusable part will increase due to the reduction of lead-time in the collection and disassembly process using NCD. In numerical experiments, the utility of NCD in a remanufacturing system considering PLC is investigated. The input quantities of both new parts and reusable parts for each production process, and the expected minimal total operating cost for the remanufacturing system when using NCD are compared with that when not using NCD.
