Green Supply Chain Management Capability Evaluation Using Neutrosophic TwoFold Algebra Decision Model

Green Supply Chain Management (GSCM) has become a priority for organizations striving to improve sustainability while maintaining competitiveness. However, assessing GSCM capabilities is complicated by the uncertain, ambiguous, and interrelated nature of the criteria involved. This paper introduces a novel evaluation approach based on Neutrosophic TwoFold Algebra (NTFA) decision model, which integrates classical algebra with neutrosophic logic to represent uncertainty in three dimensions: truth, indeterminacy, and falsity. A real-worldinspired case study from the electronics manufacturing sector illustrates the methodology. The decision model captures complex evaluations, incorporates expert judgment, and demonstrates robustness through sensitivity analysis and validation using Spearman's correlation. The results offer valuable insights for both practitioners and educators.
