Abstract: To improve the trust degree and resource scheduling efficiency among the participants in the cloud manufacturing system,explore the cloud manufacturing system based on the double blockchain structure was studied.The application of blockchain technology in the cloud manufacturing system was analyzed,and the business processes on the public chain of enterprise information and the federated chain of manufacturing resources were designed.The resource scheduling algorithm was written in the smart contract of the manufacturing resource chain to perform resource scheduling automatically.A multi-objective resource scheduling model considering innovation and matching was established.The fast elitist Non-Dominated Sorting Genetic Algorithm (NSGA-Ⅱ) was used to solve the model.The effectiveness of the proposed double-chain structure and resource scheduling model was verified with contrast experiments.The results showed that the manufacturing resource scheduling had a better set of non-dominated solutions and the resource scheduling speed was improved after the mutual trust among the participating nodes in the cloud manufacturing system based on the double-chain structure.
