Lean Manufacturing Systems

Lean Manufacturing Systems is a systematic methodology, originating from the Toyota Production System, focused on the relentless elimination of waste ("Muda") within a production process to maximize customer value. As a core discipline in industrial engineering, it shifts manufacturing from a forecast-driven "push" system to a customer-demand-driven "pull" system, utilizing principles like Just-in-Time (JIT) inventory, continuous flow, and a culture of continuous improvement (Kaizen). The ultimate goal is to create a highly efficient, responsive, and streamlined operation that delivers high-quality products with minimal resources, cost, and lead time.
