This study presents a structured systematic literature review on the integration of Lean Warehousing, ABC–FSN inventory classification, and Industry 4.0 technologies in strategic food warehouse management. The review follows the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol to ensure transparency and methodological rigor. A total of 15 high-quality articles were selected from an initial pool of approximately 800 records based on predefined inclusion and exclusion criteria. Rather than generating primary empirical results, this study performs a cross-study analytical synthesis to identify patterns, methodological approaches, and reported performance outcomes in the literature. The findings indicate that Lean Warehousing effectively reduces non-value-added activities and improves process flow, while ABC–FSN classification enhances inventory prioritization by combining product value and movement dynamics. Industry 4.0 technologies, including IoT, robotics, and data analytics, further strengthen warehouse responsiveness through real-time monitoring and adaptive decision-making. This study identifies that the integration of these approaches remains fragmented in existing literature and proposes a structured conceptual alignment across operational, tactical, and digital layers. The paper contributes by highlighting interaction mechanisms between Lean processes, inventory classification, and digital technologies, providing a foundation for future empirical validation in strategic food logistics systems.
