Blockchain-based data control for complex product assembly collaboration process

The collaborative development model of complex products brings the challenge to the data interaction management. There are many manufacturers and suppliers involved in the whole life cycle of the assembly process, which makes it difficult to ensure the data security and traceability. The Hyperledger-Fabric architecture in blockchain technology has modular design, pluggable architecture, complete authority control and security, which can well solve the data security and traceability management in the collaborative development of complex products. Therefore, this paper proposes a framework based on the Hyperledger-Fabric architecture of blockchain for the whole life cycle data management of complex products. We also demonstrate the effectiveness of our proposed new framework integrating blockchain technology through the case of quality data control during the aircraft final assembly collaborative process.
