- Abstract:
- The ability of blockchain to record transactions and automatic execution feature in smart contracts, increase the speed of the supply chain and reduce unnecessary delays. A blockchain-enabled supply chain is more dynamic and responds to changes faster. This makes many processes more efficient in the supply chain. Supplier performance evaluation is an essential field in Supply chain management. At any time, by recording real-time data through smart contracts in the blockchain, it is possible to see the supplier’s performance in different aspects according to all the information recorded up to that moment. This research investigates the use of smart contracts and blockchain in solving supply chain management challenges. Then, a bidding system for purchasing goods and evaluating suppliers' performance is presented using smart contracts. Next, the smart bidding system and the traditional bidding system are simulated. The efficiency of the proposed model is justified by the reduction of the payment cycle time and the reduction of the shipment delivery time. This system records the underlying information for performance evaluation completely and accurately and prevents incorrect scoring and unfair ranking caused by subjective judgments. Reducing the assessment period and supply risk are other advantages of the proposed system. By selecting the criteria in the smart contracts, buyers can see the performance score of suppliers according to each criterion without paying any transaction fees, and finally, choose the right supplier according to their strategy and priorities. To demonstrate the application of smart contracts in supplier performance evaluation, the proposed system has been implemented as a case study in the leather industry. Questionnaires were provided to academic and industry experts to determine the weights of the criteria. Transactions of the proposed smart contracts in three months were simulated to demonstrate their application in evaluating suppliers' performance. Then, the evaluation and ranking of suppliers have been done using multi-criteria decision-making algorithms: the best-worst method (BWM) and WASPAS
