SmartBuy — AI Decision Support System for Raw Materials
E-Hub × Damm Hackathon 2026
Should we buy now, wait, hedge, or monitor?
What we do
SmartBuy is a Decision Support System that transforms raw commodity price data, energy signals, satellite indicators, and real-time news into a single actionable procurement recommendation per raw material — with full explainability at every step.
It is not a price forecasting tool. It is a procurement timing engine built specifically for a company that buys, not trades.
Four possible recommendations
| Action | Meaning | When triggered |
|---|---|---|
| BUY | Order now at current price | Price below average + supply risk rising + trend up |
| WAIT | Delay purchase | Price falling + supply comfortable + no urgency |
| HEDGE | Lock in current price via forward contract | Supply risk HIGH but price uncertain |
| MONITOR | No action needed | Stable conditions — reassess in 5–7 days |
Materials Covered
| Material | Model | Key Signal |
|---|---|---|
| Aluminium | 5-layer specialist model | China 45Mt cap utilisation |
| Barley | 5-layer specialist model | NDVI + Protein Paradox |
| vPET | Generic 4-component model | Oil price correlation |
| rPET | Generic 4-component model | EU 30% mandate compliance |
| Energy (TTF) | Generic 4-component model | Strait of Hormuz / LNG disruption |
Strategic Decision Drivers
Aluminium: Supply Rigidity & Energy
- China’s 45Mt Cap: Tracks the legal production ceiling in China. As utilization nears 96%, supply becomes inelastic, making prices hyper-sensitive to demand shocks.
- Energy Input Delta: Monitors the spread between EU Electricity prices (smelter viability) and China Coal (global cost floor) to determine regional supply shifts.
- Yunnan Hydropower Proxy: Real-time rainfall monitoring in China's smelting hubs to anticipate power-related supply curtailments before they hit the LME.
Barley: Quality & Climate Yield
- The Protein/Quality Gap: Predicts the availability of Malting-grade vs. Feed-grade barley. High-temperature forecasts during June are flagged as a risk to grain quality, even if total harvest volume remains high.
- Fertilizer Link: Correlates Natural Gas (TTF) fluctuations with future harvest yields via nitrogen fertilizer affordability and farmer planting intentions.
FinBERT News Scoring
- Real headlines fetched daily from Google News RSS, classified using HuggingFace's ProsusAI/finbert model. Procurement signal derived from aggregate sentiment, not individual headlines.
