- **Sustainability Tracking**: Carbon footprint and ESG compliance monitoring

## 📊 Core Concepts

### 1. Supply Chain Data Model

```typescript
{
  "orderId": "ORD-2025-001234",
  "supplier": {
    "id": "SUP-5678",
    "name": "Global Components Inc.",
    "tier": 1,
    "rating": 4.8
  },
  "items": [{
    "sku": "CHIP-A100",
    "quantity": 1000,
    "unitPrice": 45.50,
    "blockchain": {
      "hash": "0x7f8c...",
      "verified": true
    }
  }],
  "logistics": {
    "mode": "air",
    "currentLocation": "Hong Kong",
    "eta": "2025-12-30T14:00:00Z"
  },
  "sustainability": {
    "carbonFootprint": 125.5,
    "esgScore": 85
  }
}
```

### 2. Blockchain Traceability

Every product in the supply chain can be tracked through an immutable blockchain ledger:

```
Origin → Manufacturing → Quality Check → Packaging → Shipping → Distribution → Retail
   ↓           ↓              ↓             ↓           ↓            ↓          ↓
  Hash       Hash           Hash          Hash        Hash         Hash       Hash
```

### 3. Risk Scoring Algorithm

```
Risk Score = Σ (Factor Weight × Factor Value)

Factors:
- Supplier Reliability (30%)
- Geopolitical Risk (20%)
- Financial Stability (15%)
- Quality History (15%)
- Delivery Performance (10%)
- Compliance Status (10%)
```

## 🔧 Components

### TypeScript SDK

```typescript
import {
  SupplyChainSDK,
  createPurchaseOrder,
  trackShipment,
  verifyBlockchainProvenance,
  calculateRiskScore
} from '@wia/ind-023';

const sdk = new SupplyChainSDK({
  apiKey: 'your-api-key',
  blockchain: {
    network: 'ethereum',
    contractAddress: '0x...'
  }
});

// Create purchase order
const order = await sdk.createPurchaseOrder({
  supplierId: 'SUP-5678',
  items: [{
    sku: 'CHIP-A100',
    quantity: 1000,
    unitPrice: 45.50
  }],
  deliveryDate: '2025-12-30',
  terms: 'NET30'
});

// Track shipment in real-time
const tracking = await sdk.trackShipment('SHIP-2025-001234');
console.log(`Current location: ${tracking.location}`);
console.log(`ETA: ${tracking.eta}`);
console.log(`Status: ${tracking.status}`);

// Verify product authenticity via blockchain
const verification = await sdk.verifyProvenance('CHIP-A100', '0x7f8c...');
console.log(`Verified: ${verification.isAuthentic}`);
console.log(`Origin: ${verification.origin}`);
console.log(`Journey: ${verification.journey.length} checkpoints`);

// Calculate supplier risk score
const risk = await sdk.calculateRiskScore('SUP-5678');
console.log(`Risk Score: ${risk.score}/100`);
console.log(`Risk Level: ${risk.level}`); // LOW, MEDIUM, HIGH
```
