Blockchain-Enabled On-Chain Servitization for Resources Matchmaking in Social Manufacturing

The emergence of social manufacturing (SMfg) has accelerated the evolution of the organizational form of SMfg resources. The management structure of manufacturing enterprises tends to flatten. However, due to the multi-dimensional heterogeneity of SMfg resources, there are interoperability and compatibility problems in the integration process, which hinder their digitization. Thus, this paper proposes a blockchain-enabled on-chain servitization (Bc-OcS) approach to integrate SMfg resources through digital twin and promote the production service trading with transparency and traceability. A refined model-view-controller (R-MVC) architecture is designed for structuring digital twins so that they can be easily expanded or reconfigured to suit the difference of SMfg resources. Furthermore, an on-chain manufacturing servitization approach is proposed based on a cross-blockchain to realize three-dimensional visibility and traceability for resources, demands and service proceeding.
