Abstract

Lean manufacturing has long been a foundational strategy for enhancing productivity, reducing operational waste, and improving overall efficiency in mechanical industries. Initially developed as part of the Toyota Production System, lean principles focused on eliminating non-value-adding activities and streamlining processes using a set of well-established tools such as 5S, Kaizen, Kanban, and value-stream mapping. Over the decades, these principles have been adopted and refined globally, particularly within the mechanical sector, to optimize shop floor operations, minimize lead times, and improve product quality. However, the advent of Industry 4.0 has brought a paradigm shift in how lean manufacturing is perceived and implemented. This systematic review traces the evolution of lean manufacturing—from its early, tool-centric approaches to its present-day integration with advanced digital technologies. The paper explores how the incorporation of smart systems, including the Internet of Things (IoT), artificial intelligence (AI), digital twins, and cyber-physical systems (CPS), has transformed traditional lean practices into intelligent, adaptive frameworks. These digital enhancements allow for real-time data acquisition, predictive maintenance, automated quality checks, and dynamic scheduling, enabling a new generation of lean systems—referred to as Lean 4.0. Moreover, the paper highlights key case studies from leading mechanical manufacturing firms that have successfully merged lean principles with digital transformation initiatives. It also discusses the challenges organizations face in this transition, including technological barriers, workforce resistance, skill gaps, and cybersecurity concerns. Finally, the review outlines future trends and opportunities for mechanical industries to harness the full potential of digital lean systems.

Keywords: Lean manufacturing, Industry 4.0 integration, digital lean systems, smart manufacturing, mechanical production efficiency, cyber-physical systems in lean
