Integrating Fuzzy Decision‐Making and Blockchain for Stakeholder Collaboration in Organic Agriculture Supply Chain Management

ABSTRACT Blockchain‐enabled organic agricultural supply chains enhance the product validation, transparency, and traceability using the shared, immutable ledger. However, many traditional methods struggle to handle uncertainty in decision‐making, struggling with a lack of trust and a lack of transparency in certification and provenance verification, and being adapted to static stakeholder needs. To overcome these issues, this research proposes an Adaptive Co‐Creation Blockchain for the organic agricultural supply chains framework. A Hybrid Delphi–Fuzzy Trust‐Weighted Analytic Hierarchy Process (HDFT‐AHP) method is employed to identify, validate, and prioritize 15 critical value co‐creation factors over three domains. To assign factor weights, this method integrates iterative fuzzy Delphi consensus with fuzzy AHP pairwise comparisons. Based on the prioritization, the Trust‐Centric Blockchain‐Embedded E‐Commerce (TC‐BEE) is employed to transform the stakeholder expectations into a blockchain‐enabled digital marketplace, incorporating governance smart contracts with certification and hybrid on‐chain and off‐chain data storage, multiple‐layer blockchain validation, and stakeholder‐facing dashboards to illustrate the combination of representative governance, integrated supply chain management, and real‐time monitoring. The stakeholder input is collected and analyzed by the Adaptive Trust‐Weighted Feedback Loop (ATWFL) to provide consistent improvement. This mechanism authorizes the operation to learn from the stakeholder participation, adjust regulatory criteria, and enhance the collaboration over time. Experimental evaluation demonstrates the framework's robustness, achieving higher Precision (98.32%), Decision‐Validation Accuracy (98.98%), F1‐Score (97.98%), Recall (97.65%), R 2 (0.98), and a lower MSE (1.76) and RMSE (1.33), confirming the effectiveness in building trust, strengthening collaboration, and encouraging environmental policy‐making in organic agricultural supply chains.
