Abstract

Procurement has faced major challenges due to the collapse of global supply chains in the course of the SARS-COV2 pandemic, and non-critical items have become critical bottlenecks. Additive manufacturing (AM) is an emerging technology that serves as a local supply source and can mitigate some of these bottlenecks. For example, it was possible to source medical spare parts and protective equipment via AM, even when the globally arranged traditional (formative or subtractive manufacturing) supply sources failed. To that end, this research examines how supply risks change when sourced via an AM supply source rather than through supply sources that use traditional manufacturing (TM). This study assesses supply risk using a Delphi study from July to October 2020. The findings were further explored using discriminant analysis. A mix of TM supply sources with AM (‘hedging’) can minimise the overall supply risks. The discussion conceptualises a portfolio model to determine whether to source demands via TM, AM, or by hedging. The implications of hedged manufacturing are linked to the modern portfolio theory.

SARS-COV-2期间增材制造供应风险缓解效果的德尔菲研究
由于SARS-COV2大流行期间全球供应链的崩溃,采购面临重大挑战,非关键项目已成为关键瓶颈。增材制造(AM)是一种新兴技术,可以作为当地的供应来源,缓解这些瓶颈。例如,即使全球安排的传统(形成式或减法式制造)供应来源失败,也可以通过增材制造采购医疗备件和防护设备。为此,本研究考察了通过增材制造供应来源而不是通过使用传统制造(TM)的供应来源采购时供应风险的变化。本研究利用德尔菲研究评估了2020年7月至10月的供应风险。使用判别分析进一步探讨了这些发现。TM供应来源与AM(“对冲”)的组合可以最大限度地降低整体供应风险。讨论概念化了一个投资组合模型,以确定是否通过TM、AM或对冲来获取需求。对冲制造业的影响与现代投资组合理论有关。

期刊介绍: The mission of the Journal of Purchasing & Supply Management is to publish original, high-quality research within the field of purchasing and supply management (PSM). Articles should have a significant impact on PSM theory and practice. The Journal ensures that high quality research is collected and disseminated widely to both academics and practitioners, and provides a forum for debate. It covers all subjects relating to the purchase and supply of goods and services in industry, commerce, local, national, and regional government, health and transportation.
