Impact on Manufacturing
- High precision and quality in products.
- Reduced labor costs and human error.
- Lean manufacturing became widespread.
- Increased flexibility for producing multiple product variants.
4. Fourth Industrial Revolution (2000s–Present)
Overview
- Called Industry 4.0.
- Focuses on smart, interconnected factories using digital technology and AI.
Key Innovations
- Cyber-Physical Systems: Machines integrated with digital control.
- Internet of Things (IoT): Real-time data from sensors for predictive maintenance.
- Artificial Intelligence & Machine Learning: Optimized production, quality control.
