# Deploy to GitHub Pages
npm run deployThis runs the build and deploys the dist folder to the gh-pages branch.
Scenario: A global OEM (Hyundai Motor Group) manages a multi-billion-dollar vehicle pipeline across luxury (Genesis G80), volume (Venue, Elantra), and EV segments (IONIQ 5). High-DSI luxury models accumulate holding costs while volume segments suffer from stockouts. This dashboard provides the decision-support layer to:
- Detect – Identify which regional channels have stagnant capital
- Model – Simulate inventory redirection and capital recapture scenarios
- Execute – Approve strategic liquidation with transparent ROI calculations
The dashboard tracks 6 vehicle models with realistic metrics:
| Model | Segment | Stock | Monthly Sales | Unit Cost | Category |
|---|---|---|---|---|---|
| Genesis G80 | Luxury Sedan | 14 | 3.2 | $56,000 | Luxury |
| Hyundai Venue | Compact SUV | 58 | 62 | $19,800 | Volume |
| Hyundai IONIQ 5 | EV SUV | 32 | 38 | $45,000 | EV |
| Hyundai Santa Fe | Mid-size SUV | 24 | 28 | $36,000 | SUV |
| Hyundai Elantra | Sedan | 42 | 55 | $21,500 | Volume |
| Hyundai Palisade | Full-size SUV | 18 | 5.5 | $48,000 | Luxury |
