In the current industrial revolution, additive manufacturing (AM) embodies a promising technology that can enhance the effectiveness, adaptability, and competitiveness of supply chains (SCs). Moreover, it facilitates the development of distributed SCs, thereby enhancing product availability, inventory levels, and lead time. However, the wide adoption of AM in industrial SCs creates various challenges, leading to new difficulties for SC design. In this context, this article proposes a new design approach to AM SCs using optimization methods. More specifically, the proposed approach, comprising the p-median and mixed-integer linear programming models, considers the decision of deploying productive resources (3-D printers) in specific locations of generic spare part SCs. The approach was evaluated in a real-world use case of an elevator maintenance service provider. The obtained results demonstrated the promising capabilities of the proposed design approach in managing the challenges arising from the forthcoming widespread use of 3-D printers in manufacturing SCs.

备件供应链增材制造的设计方法


在当前的工业革命中，增材制造（AM）体现了一种有前途的技术，可以增强供应链（SC）的有效性、适应性和竞争力。此外，它还促进了分布式供应链的开发，从而提高了产品可用性、库存水平和交货时间。然而，增材制造在工业SC中的广泛采用带来了各种挑战，给SC设计带来了新的困难。在此背景下，本文提出了一种使用优化方法的 AM SC 的新设计方法。更具体地说，所提出的方法包括 p 中值和混合整数线性规划模型，考虑在通用备件 SC 的特定位置部署生产资源（3D 打印机）的决策。该方法在电梯维护服务提供商的实际用例中进行了评估。获得的结果证明了所提出的设计方法在应对即将在 SC 制造中广泛使用 3D 打印机所带来的挑战方面具有良好的能力。
