The role of blockchain technology in the sustainability of supply chain management: Grey based dematel implementation

Decentralized, transparent, immutability, irreversible, autonomy, open source, anonymity, ownership and uniqueness, source, contract automation are at the forefront of the features that allow blockchain technology to be accepted within the sectors. Thanks to these features, it has an important potential in terms of applicability, as well as in supply chain management, as in many other fields. In this study, the compatibility and impact level of the features of blockchain technology with the sustainability of supply chain management are investigated. Within the scope of supply chain management, effective information sharing, integration between processes, trustworthy, systematic data management, auditability, transparency, strong relationship between stakeholders, high efficiency, quick answer, ability to increase sustainability, transition to digitization, uncertain legal status, new technology, integration compatibility with other technologies, optimizing time parameters are evaluated. In the results obtained with the Grey Relational Analysis-based DEMATEL method, effective information sharing, integration between processes, systematic data management, quick answer, uncertain legal status, new technology, and integration compatibility with other technologies are included in the group affecting other criteria. Within the scope of the study, the characteristic features of blockchain technology for supply chain management are interpreted with relationship map and graph diagram. The study provides both theoretical and practical contributions by drawing attention to the compatibility of the blockchain in supply chains, and guides the employees in the supply chain line on how they can best guide their companies and on which parameters they can gain by enabling them to adopt blockchain technology. With blockchain technology, it offers the opportunity to achieve higher efficiency with less time, less cost and faster response, which can realize its sustainability mission, which includes each of the economic, social and environmental dimensions.
