| Environmental issues in supply chains has been serious for not only global warming but also material starvation. End-of-life assembly products at recycling factories should be disassembled environmentally and economically in consideration of not only low carbonization but also material circulation. Parts with higher recycling and CO2 saving rates should be selected and manually disassembled, however, the manual disassembly brings higher cost instead of crushing the parts. Moreover, these parts selection also affects a disassembly line balancing. This paper addresses the disassembly cost, recycling and CO2 saving rates simultaneously for an optimal environmental and economic parts selection in a disassembly system design, and uses a multi criteria decision making among them to harmonize the low-carbon and closed-loop supply chains for the EOL assembly products by the disassembly. |
