Blockchain-Based Information Sharing Mechanism for Complex Product Supply Chain

In recent years, the rapid development and widespread application of new generation information technology has profoundly influenced the new round of manufacturing industry transformation. Information sharing is a key factor in determining the efficiency of supply chain operations and remains one of the hot issues of supply chain management research. Considering the disrupted and unstable information flow of current complex product supply chain, this paper constructs a blockchain-based complex product supply chain information sharing system (BC-CPSCISS). A blockchain-based information storage and access method is proposed to promote secure, transparent, and efficient information interaction. A decision model for complex product supply chain information sharing was established based on Stackelberg game theory. The impact of blockchain application cost and its value gain on the optimal decision is herein discussed. The condition of applying blockchain technology under economic objective is also analyzed. The results indicate that complex product supply chain enterprises should fully consider the cost of applying blockchain and its impact on overall economic benefits before making their decision.
