ABSTRACT

Make-to-order (MTO) supply chains (SC), common in aerospace industries, are very complex compared to mass production chains. Moreover, one of the significant long-term challenges is sustainability performance across its entire supply chain. However, this is not an easy task given the complexity involved, so decision support tools are fundamental instruments in understanding the entire supply chain from a sustainability performance perspective. Using simulation as a research method, this article proposes a hybrid and hierarchical performance assessment model, considering key sustainability indicators. The model is hybrid due to the use of different simulation methods– System Dynamics (SD), Discrete Event Simulation (DES), and Agent-based simulation (ABS). The model is applied to an aerospace manufacturer’s real case to assess the sustainability performance of alternative SC. Unlike existing contributions, this work addresses the make-to-order supply chain from a sustainability performance perspective and does not compromise the representation of the diverse manufacturing functions and resources.

摘要

与大规模生产链相比，航空航天工业中常见的按订单生产 (MTO) 供应链 (SC) 非常复杂。此外，一项重大的长期挑战是其整个供应链的可持续性绩效。然而，考虑到所涉及的复杂性，这并非易事，因此决策支持工具是从可持续性绩效的角度了解整个供应链的基本工具。本文使用模拟作为研究方法，提出了一种混合的分层绩效评估模型，同时考虑了关键的可持续性指标。由于使用了不同的仿真方法——系统动力学 (SD)、离散事件仿真 (DES) 和基于代理的仿真 (ABS)，该模型是混合的。该模型应用于航空航天制造商的真实案例，以评估替代 SC 的可持续性绩效。与现有的贡献不同，这项工作从可持续性绩效的角度解决了按订单生产的供应链，并且不会损害不同制造功能和资源的代表性。
