The framework integrates hierarchical fuzzy analytic hierarchy process (fuzzy AHP) for multi-criteria decision-making, advanced data preprocessing techniques including auto encoders and feature engineering, and diverse AI models such as deep reinforcement learning (DRL), convolutional neural networks (CNN), and gradient boosting machines (GBM). A comprehensive digital twin environment simulates realtime plant operations, enabling validation and scenario analysis. The proposed methodology employs a ten-round decision refinement process, incorporating expert judgment, sensor data, visual defect detection, and predictive analytics to dynamically control process parameters, quality assurance, and resource allocation. The case study conducted within a Tehran dairy processing plant demonstrates substantial improvements in operational metrics: a reduction of energy consumption by 8%, microbial counts by 15%, waste by 10%, and zero safety violations over a three-month period. The integration of explainable AI (XAI) techniques enhances interpretability and stakeholder trust. The findings underscore the potential of such integrated AI-driven systems to revolutionize Industry 4.0 practices in food manufacturing offering pathways toward smarter, safer, and more sustainable production paradigms. This research provides a scalable, adaptable blueprint for future deployment across diverse industrial contexts.
