Industry 4.0 is fundamentally built upon nine interconnected pillars designed to establish the "smart factory."
These core technologies are: 1. IIoT (connecting machines), 2. Big Data & Analytics (real-time insights), 3. Cloud Computing (data infrastructure), and 4. Cybersecurity (protecting the network). They are integrated with physical processes via 5. Autonomous Robots, 6. Simulation (Digital Twins), 7. Horizontal/Vertical Integration (system connectivity), 8. Augmented Reality (human-machine interaction), and 9. Additive Manufacturing.
Collectively, these pillars enable decentralized decision-making, unprecedented efficiency, and flexible mass customization across global value chains.
It's crucial to understand that while the list is not absolute (some models cite eight or ten, often emphasizing AI as a standalone pillar), the underlying functional areas remain consistent.
The nine pillars are essentially categorized into four domains:
These pillars collectively drive decentralized decision-making and mass customization, which are the true hallmarks of the Fourth Industrial Revolution.
