ROI Summary
| Area | Expected Effect | Estimated Saving/Improvement |
|---|---|---|
| Downtime | Reduced unplanned stoppages | 30~50% |
| Decision-making | Time to assess current status | 90% faster |
| Productivity | OEE improvement | 3~8%p |
| Energy | Energy costs | 5~15% savings |
| Workforce | Training/handover | 40~60% shorter |
| Quality | Defect rate | Significant reduction |
1. Minimizing Equipment Downtime
Problem: Unexpected equipment failures halt production lines and cause massive losses.
Solution:
- AI anomaly detection (IBM Granite TSPulse) detects failure signs in advance from sensor data
- Forecasting models (TinyTimeMixer) predict future trends and recommend inspection timing
- Alarm pattern analysis identifies root causes of recurring failures
Expected Effect:
- 30~50% reduction in unplanned downtime
- Shift from preventive maintenance to Predictive Maintenance
- Reduced emergency repair costs
2. Faster Operational Decision-Making
Problem: Data is scattered across multiple systems, so assessing current status takes time.
Solution:
- A single natural-language question simultaneously runs real-time data + AI analysis + document search
- Before: check SCADA → analyze in Excel → search manuals (30 minutes~1 hour)
- PlantPulse AI: "Analyze the injector status" → a comprehensive report in under 10 seconds
Expected Effect:
- 90% reduction in time to assess current status
- Automatic generation of daily briefings for shift handover
- Non-specialists can perform expert-level analysis
3. Improved Quality and Productivity
Problem: It is difficult to identify the causes of declining OEE (Overall Equipment Effectiveness), and quality deviations are addressed too late.
Solution:
- Real-time monitoring and anomaly detection of OEE (availability/performance/quality)
- Quality trend prediction per work order — preemptive action before defects occur
- Immediate identification of bottlenecks through comparative OEE analysis by line and by equipment
Expected Effect:
- 3~8%p OEE improvement (vs. industry average)
- Lower defect rates and reduced rework costs
- More accurate production planning
4. Reduced Energy Costs
Problem: Energy consumption patterns are hard to understand, and inefficient areas go unaddressed.
Solution:
- Anomaly detection and forecasting on EMS (Energy Management System) data
- Comparative analysis of energy consumption by equipment and by line
- Carbon emissions monitoring and regulatory compliance
Expected Effect:
- 5~15% reduction in energy costs
- Automatic data collection for ESG reports
- Proactive response to carbon regulations
5. Preserving and Transferring Field Knowledge
Problem: Tacit knowledge is lost when skilled technicians retire, and onboarding new staff takes too long.
Solution:
- Instant search of manuals/SOPs/incident reports via the RAG system
- Visual understanding of plant structure and equipment relationships through the ontology
- AI recommends corrective actions based on past cases
Expected Effect:
- 40~60% shorter training period for new technicians
- Prevention of technical knowledge loss — organizational capability preserved
- Higher compliance rates with regulations and safety procedures
6. Unified Visibility
Problem: SCADA, MES, ERP, and document systems are siloed, making the full picture impossible to see.
Solution:
- Unified access to sensor data + production metrics + equipment relationships + technical documents from a single AI interface
- Full visibility into the plant hierarchy (site → area → line → equipment → sensor)
- Cross-domain analysis — "What impact does this alarm have on OEE?"
Expected Effect:
- Elimination of data silos
- Closing the information gap between management, the field, and maintenance teams
- Establishment of a data-driven decision-making culture
