Industry 4.0: A roadmap to digital Supply Chains

Today's supply chains data should be harnessed more than ever. This data is the oil of the 21st century and industry 4.0 technologies are the engines to burn it. More precisely, thanks to internet of things devices, supply chains generated huge amounts of data. However, with the adequate tools, insights could be extracted for enhanced decision-making. In fact, industry 4.0 offers nine key technologies to address supply chain data. the aim of this paper is to illustrate the role of industry 4.0 towards supply chains, highlight its key technologies, clarify the importance of mathematical optimization in the era of digitalization and match these key technologies with supply chain processes so as to deliver customized products at the right time and in the right place.
