Traceability and Management Platform for Agricultural Product Supply Chain based on Hyperledger Fabric and deep Q Network
In order to realize the tracing and traceability of the agricultural products and improve the supply chain infor-mation management,thereby ensuring the food safety of consumers and increasing the profits of system participants,a blockchain and deep reinforcement learning-based agricultural product supply chain management solution is proposed.Firstly,a blockchain-based agricultural product supply chain management system is deployed using Hyperledger Fabric to monitor and trace the entire trade and delivery process of agricultural products from the origin to the end consumer.Secondly,Deep Q Netwrok(DQN)is used in the data storage pool to realize efficient decision-making in the produc-tion and storage of agricultural products,and maximize the interests of the participating members of the supply chain.The REST API is used to realize the communication between the blockchain network and the data storage pool module,allowing system members to perform efficient and safe interaction.The security analysis and simulation results show that the proposed system can achieve credible,accountable,auditable and decentralized agricultural supply chain manage-ment,the system response and query delays can meet the needs of practical applications,and the proposed DQN algo-rithm can effectively improve the production and storage decisions of the supply chain members.
