Digital twin-driven smart supply chain

Today’s supply chain is becoming complex and fragile.Hence,supply chain managers need to create and unlock the value of the smart supply chain.A smart supply chain requires connectivity,visibility,and agility,and it needs be integrated and intelligent.The digital twin(DT)concept satisfies these requirements.Therefore,we propose creating a DT-driven supply chain(DTSC)as an innovative and integrated solution for the smart supply chain.We provide background information to explain the DT concept and to demonstrate the method for building a DTSC by using the DT concept.We discuss three research opportunities in building a DTSC,including supply chain modeling,real-time supply chain optimization,and data usage in supply chain collaboration.Finally,we highlight a motivating case from JD.COM,China’s largest retailer by revenue,in applying the DTSC platform to address supply chain network reconfiguration challenges during the COVID-19 pandemic.
