Consortium blockchain-driven decentralized organization and operation for manufacturing community in social manufacturing

Recently, social manufacturing emerges to help micro-and-small-scale manufacturing enterprises (MSMEs) to cope with service-oriented, personalized, diverse and dynamic market demand. In social manufacturing, MSMEs are usually peer-to-peer and geographically distributed, and they self-organize into manufacturing communities (MCs) to share their manufacturing resources, order and business benefit. Therefore, the decentralized organization and operation of MCs become an emergency. To solve this problem, a consortium block chain based decentralized mechanism is established for the organization and operation of manufacturing community in social manufacturing, and a corresponding reference framework is proposed to guide MCs to implement decentralized organization and operation. On this basis, three key enabled technologies are elaborated, which are mainly about the determination of verification dataset, the design of smart contract, and the definition of endorsement policy. It is expected that the reference framework proposed in this paper will provide a possible way for MSMEs to organize and operate MC without core enterprise in social manufacturing.
