摘要

The growing demand for reliable, eco-friendly healthcare solutions requires innovative manufacturing and management of custom prosthetics. This study introduces a closed-loop supply chain management system for manufacturing and end-of-life care of custom prosthetics that utilizes additive manufacturing, with a focus on environmental responsibility. Each prosthetic is tailored and produced through additive manufacturing to accurately match the anatomical requirements of each patient, ensuring a custom fit and improved functionality. To ensure high-quality custom prosthetics, a smart autonomated inspection system is integrated into the manufacturing process. At the end of their life cycle, waste prosthetics are collected, inspected, and recycled to minimize waste, conserve resources, optimize material recovery, and improve durability. A genetic algorithm is employed to minimize overall costs, integrating multiple raw material supply sites, distribution centers, and collection centers for custom prosthetics. A numerical example is analyzed, and the repercussions of the numerical example reveal that 80% of wasted prosthetics can be recycled and utilized as raw material in the production cycle. Additionally, the major cost factors are installation costs of custom prosthetics production facilities (46% of the total cost) and raw material purchasing costs (34% of the total cost). These results offer valuable insights into cost structures and the potential of recycling-based material recovery within a closed loop supply chain (CLSC) framework. This study contributes to the closed loop supply chain literature by applying closed-loop principles to a highly customized medical product domain.
