Analysis of Industry 4.0 technological enablers for sustainable supply chain transparency in a fuzzy environment

This study aims to identify various Industry 4.0 technological enablers and analyze their relationships in achieving transparency in sustainable supply chains. Initially, 17 Industry 4.0 technological enablers were selected based on an extensive literature review of sustainable supply chains and evaluated through Systems and Information Processing theories. Using the fuzzy Delphi method, these enablers were then narrowed down to 14 relevant ones. The reliability of these enablers was assessed by measuring their internal consistency using Cronbach's alpha (alpha) and McDonald's omega (omega). The fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was then used to demonstrate that blockchain, cybersecurity, big data, and artificial intelligence (AI) are the most prominent and influential enablers for enhancing transparency in a sustainable supply chain. Additionally, the cause-effect relationship of other key enablers provides evidence for a feasibility study that links sustainability with transparency across the supply chain. These identified Industry 4.0 technological enablers can assist external stakeholders and policymakers in improving transparency and advancing sustainable supply chain practices.
