A Green Supply Chain Evaluation System Based on Blockchain

For the material supply chain network entities, the horizontal integration between the entities in the traditional supply chain information management mode will inevitably lead to closed information, low data transparency, and insufficient node control ability, which greatly inhibits the efficiency of the supply chain and is not conducive to collaboration. Therefore, combined with the characteristics of decentralization, openness and transparency of blockchain and smart contract rules, a green supply chain evaluation system is designed and implemented based on blockchain. The evaluation index management module is responsible for quantifying the weight matrix of the index system corresponding to the evaluation model. The distributed database module is responsible for the collection of basic historical data and model data maintenance. The smart contract module is responsible for automatically exporting the online contract to the record contract for chain tracking. Supplier performance analysis and integrity evaluation module rely on contract performance data to monitor and supervise the whole process of suppliers. Analysis results show that the system has the characteristics of non-tampering, decentralization, multi-agent transparent participation in the whole process evaluation, and effectively improves the efficiency and level of green supply chain management.
