## 🌟 Overview

The WIA-IND-008 standard defines a comprehensive framework for smart kitchen technology, including connected appliances, automated cooking systems, recipe management, inventory tracking, and energy-efficient kitchen operations. This standard provides a unified interface for modern kitchen automation, food preparation optimization, and sustainable cooking practices.

**홍익인간 (弘益人間) - Benefit All Humanity** - This standard aims to make healthy, nutritious cooking accessible to everyone, reduce food waste, optimize energy consumption, and empower people with intelligent cooking assistance for better quality of life.

## 🎯 Key Features

- **Connected Appliances**: Smart ovens, refrigerators, cooktops, dishwashers, and small appliances
- **Automated Cooking**: Recipe-guided cooking with automatic temperature and timing control
- **Recipe Management**: Digital recipe library with nutritional analysis and substitutions
- **Inventory Tracking**: Real-time monitoring of ingredients, expiration dates, and shopping lists
- **Energy Efficiency**: Smart scheduling and power optimization across appliances
- **Nutritional Analysis**: Calorie counting, macro tracking, and dietary compliance
- **Food Safety**: Temperature monitoring, cross-contamination prevention, food storage guidelines
- **Meal Planning**: Weekly planning, batch cooking, and family preference management

## 📊 Core Concepts

### 1. Cooking Energy Calculation

```
Energy (kWh) = Power (kW) × Time (hours) × Efficiency Factor
```

Where:
- `Power` = Appliance power rating (kW)
- `Time` = Cooking duration (hours)
- `Efficiency Factor` = 0.7-0.95 (varies by appliance type)

### 2. Recipe Scaling

```
Scaled Ingredient = Original Amount × (Target Servings / Original Servings)
Cooking Time Adjustment = Original Time × (New Volume / Original Volume)^(1/3)
```

### 3. Energy Efficiency Score

```
Efficiency Score = (Theoretical Min Energy / Actual Energy Used) × 100
```

### 4. Food Freshness Index

```
Freshness (%) = 100 × (1 - (Days Elapsed / Expected Shelf Life))
```

### 5. Nutritional Density

```
Nutrient Density = (Nutrient Amount per Serving / Daily Value) / (Calories per Serving / 2000)
```

## 🔧 Components

### TypeScript SDK

```typescript
import {
  SmartKitchenSDK,
  calculateCookingEnergy,
  scaleRecipe,
  trackInventory,
  analyzeMeal
} from '@wia/ind-008';

// Initialize smart kitchen
const kitchen = new SmartKitchenSDK({
  appliances: ['oven', 'cooktop', 'refrigerator', 'dishwasher'],
  energyMode: 'eco',
  timezone: 'Asia/Seoul'
});

// Start automated cooking
const recipe = await kitchen.loadRecipe('kimchi-jjigae');
const scaled = kitchen.scaleRecipe(recipe, { servings: 4 });

await kitchen.startCooking({
  recipe: scaled,
  appliance: 'smart-cooktop',
  notifications: true
});

// Track inventory
const inventory = await kitchen.getInventory();
const expiringSoon = inventory.filter(item => item.daysUntilExpiry < 3);

console.log(`Items expiring soon: ${expiringSoon.length}`);
```

## ⚡ Energy Optimization

### Appliance Energy Profiles

**Oven Baking (2.5 kW, 1 hour)**
- Preheat: 0.3 kWh (12 minutes)
- Baking: 1.8 kWh (48 minutes)
- **Total: 2.1 kWh**

**Induction Cooking (2.3 kW average, 30 minutes)**
- High heat: 0.8 kWh (10 minutes @ 3.0 kW)
- Medium: 0.5 kWh (15 minutes @ 2.0 kW)
- Simmer: 0.2 kWh (15 minutes @ 0.8 kW)
- **Total: 1.5 kWh**

**Dishwasher (Eco mode)**
- Water heating: 0.8 kWh
- Washing/drying: 0.4 kWh
- **Total: 1.2 kWh per cycle**

### Energy Saving Tips
1. **Use convection**: 25% less energy than traditional baking
2. **Batch cooking**: Cook multiple dishes simultaneously
3. **Residual heat**: Turn off early, use remaining heat
4. **Match cookware**: Use correct pan size for induction zones
5. **Eco modes**: Dishwasher eco cycle saves 30% energy
6. **Off-peak timing**: Schedule heavy tasks during low-rate hours

## 🥗 Nutritional Analysis
