Dynamic Multi-Criteria Bottleneck Severity Index (DMBSI) for Semiconductor Wafer Manufacturing: A Genetically Optimised Framework for Reentrant Production Systems
TL;DR
A new Dynamic Multi-Criteria Bottleneck Severity Index (DMBSI) was developed to identify bottlenecks in semiconductor wafer manufacturing, achieving an 8.1% improvement in cycle time predictions over existing methods.
✦ Why It Matters
Implement DMBSI to optimize bottleneck management and improve cycle times in your semiconductor manufacturing processes.
Key Takeaways
- Adopt DMBSI for real-time bottleneck identification.
- Utilize MES logs for data-driven insights.
- Focus on reducing waiting times at top bottlenecks.
- Monitor shifting bottlenecks throughout production stages.
How It Works
DMBSI integrates multiple diagnostic signals related to cycle time and process parameters, using genetic optimization to enhance its predictive accuracy. It analyzes historical data to identify the most critical bottlenecks at any given time, allowing for timely interventions.
