BLOCKCHAIN-BASED COLLABORATIVE MANAGEMENT OF JOB SHOP SUPPLY CHAIN

Blockchain supports free and reliable transactions of the production material supply chain (PMSC). However, few scholars have combined the blockchain with supply chain management. Based on blockchain, this paper explores the collaborative management of material supply chain for production and manufacturing job-shops (PMJs). Specifically, a collaborative management model was constructed, and the execution of the smart contract between PMJ and production material supplier (PMS) was explained. Then, the Stackelberg game between PMJ and PMS in the model was analysed, and the calculation method of the total benefit of PMS and PMJ was derived, under the information sharing mode of the blockchain-based PMSC model. Through trust evaluation, the dishonest companies were identified in the PMSC. To ensure the safe and reliable data sharing between the companies in our model, the probability for the dishonest companies to participate in smart contract was reduced, making it less likely for false shared data to appear in the chain. The effectiveness of the proposed blockchain-based model for the collaborative management of PMSC was proved through simulations.
