Digital twin and blockchain enhanced smart manufacturing service collaboration and management

Abstract

Recently, as the development of information technologies and personalized needs, the Industrial Internet platform based manufacturing service collaboration becomes the main method for manufacturing collaboration, where multiple interest-independent stakeholders involve. However, the distrust between stakeholders and the platform (distrust among collaborators and the doubts of data accuracy) hinders the development of it. Manufacturing service that are mainly encapsulated by static information cannot well adapt to changing physical conditions, which will disappoint the stakeholders for data accuracy. In addition, distrust among unfamiliar stakeholders is also the reason to keep users away from the platform. Digital twin (DT) and blockchain (BC) technologies have been widely studied in many fields, as they can provide a trustful method for the process of cyber-physical integration. In view of the insufficient interaction of physical and cyber spaces and distrust challenges encountered in the development of the current Industrial Internet platform based manufacturing service collaboration, this paper proposes a DT-BC enhanced manufacturing service collaboration mechanism towards the Industrial Internet platform. In addition, based on the analysis of manufacturing collaboration development, the DT-BC enhanced manufacturing service management, challenges, and future work of implementing DT-BC enhanced manufacturing service management for the Industrial Internet Platform are discussed.
