Supply Chain Decision Model Based on Blockchain: A Case Study of Fresh Food E-Commerce Supply Chain Performance Improvement

Aiming at the problems in the performance improvement of the fresh food e-commerce supply chain, in this article, the author defines the constraints on the performance improvement of the fresh food e-commerce supply chain and determines the demand to improve performance in quality and safety, logistics traceability, resource integration, and benefit distribution. In addition, this article conducts coupling analysis on the characteristics of blockchain technology, such as intelligent contract, information sharing, traceability, and performance improvement requirements. The author embeds the alliance chain in the fresh food e-commerce supply chain and designs the blockchain information platform model from four levels: application layer, contract layer, network layer, and data layer, with the purpose of optimizing and improving the performance of the fresh food e-commerce supply chain. What is more, the Stackelberg game model between the supplier and the e-commerce platform was constructed to study and compare the profit changes of the fresh food e-commerce supply chain before and after the application of the blockchain information platform. Finally, the result of Stackelberg game is numerically simulated by Matlab software. The results show that blockchain technology is a booster for the development of the fresh food e-commerce supply chain to a higher stage of the whole industry chain management, coordination, and integration. Investing in the blockchain system within a certain budget range can not only improve the reliability of products, but also improve the performance of each main component of the fresh food e-commerce supply chain, as well as the overall performance. Results can offer a theoretical guidance for producer and retailer in investing in BIP, pricing decision, and supply chain coordination after applying BIP.
