Real-Time Location System
Real-time location system is the technology framework that continuously estimates and reports the location of lots, carriers, and material assets inside the fab - it reduces search latency and improves flow-control decisions.
What Is Real-time location system?
- Definition: RTLS infrastructure using sensors, tags, and positioning algorithms for live asset tracking.
- Tracking Granularity: Can provide zone-level, aisle-level, or exact interface-point location depending on design.
- Data Integration: Feeds MES, dispatch systems, and logistics dashboards.
- Signal Technologies: May use RFID, infrared, Wi-Fi, UWB, or hybrid location methods.
Why Real-time location system Matters
- Search Elimination: Reduces non-value time spent locating lots and carriers.
- Dispatch Accuracy: Improves routing decisions with current location awareness.
- Cycle-Time Control: Faster lot discovery and movement coordination shortens waiting periods.
- Exception Management: Speeds response to stuck, misplaced, or delayed carriers.
- Operational Transparency: Provides actionable visibility for logistics and production coordination.
How It Is Used in Practice
- Coverage Design: Deploy sensors and readers to eliminate location blind spots.
- System Coupling: Integrate RTLS events with AMHS and MES for closed-loop dispatch.
- Performance Monitoring: Track location accuracy, latency, and unresolved-location event rates.
Real-time location system is a high-impact logistics visibility tool for fabs - accurate live location data improves dispatch quality, reduces delays, and strengthens control over material flow execution.
