Today, due to global competition for lower prices and higher quality and the focus of automakers on their core expertise, automotive spare parts are being outsourced and the spare parts supply chain is completely decentralized. Be the decentralized supply chain structure has the effect of Double Marginalization and Bullwhip, which ultimately undermines supply chain performance. Therefore, designing contracts and various strategies is important to improve decentralized supply chain performance. Vendor Managed Inventory (VMI) is one of these strategies that has been considered in the last two decades. Based on this approach, the automaker provides the information of product's demand, number and it’s shape for the supplier and instead, the supplier assumes responsibility for the car inventory control. Therefore, sharing information among supply chain members is important.
Failure to introduce technology and an appropriate architecture pattern for sharing information in the supply chain of automotive spare parts with a decentralized perspective is a gap in past research. In order to solve the existing gap, the BlockChain technology has been selected as a safe and completely decentralized way for information sharing, and an appropriate architectural model for sharing the necessary information in the VMI system in the supply chain of automotive spare parts using the ABAS method provided and it is evaluated by the ATAM method.
The evaluator team in the first workshop considers the proposed model to be valid in four aspects of security, flexibility, extensibility and efficiency, taking into account the sensitivity points. Also, the evaluator team in the second workshop considers the proposed model to be valid in two features of usability and flexibility, considering the sensitivity points, but considers weakness in terms of support for centralized systems. Given the outcomes of the evaluation and their final examination, the proposed model can be considered useful.
According to the work done, the innovation of this research is the use of BlockChain technology to share information in the VMI system in the supply chain of automotive spare parts, and the proposed model can be used in the VMI systems of the automotive industry.
