Digital twin for sustainable manufacturing supply chains: Current trends, future perspectives, and an implementation framework

Abstract

• The research mainly addresses digital twin for sustainable manufacturing supply chains. • A systematic literature review of 70 research papers on various dimensions of a digital twin for sustainable manufacturing is presented. • Technologies such as IoT, cloud computing, and blockchain have increased the potential of digital twin and the digital twin should include the "things" and "humans" from the entire supply chain. • A sustainable digital twin implementation framework for the supply chain is presented as an outcome of this study. A digital twin is an integration of virtual and physical systems using disruptive technologies. More precisely, it is a method of developing sustainable, intelligent manufacturing systems for attaining robust quality, reducing time, and customized products using real-time information throughout the product life cycle. This paper presents a systematic literature review of 98 research papers on various digital supply chain twin dimensions with sustainable performance objectives. The selected papers were reviewed and classified into three broad categories: components of the digital twin, applications in the manufacturing supply chain, and sustainability. Based on the review and future perspectives from the study, we suggest that advancements in technologies such as IoT, cloud computing, and blockchain have increased the potential of digital twin applications in the supply chain. The results indicate that a digital supply chain twin should include the things and humans from the entire supply chain and not be restricted to the local manufacturing systems. Based on our review findings, we present a sustainable digital twin implementation framework for supply chains. The proposed framework will guide future practitioners and researchers.
