+    center_lng=2.3522,
+    bounds={'north': 48.9, 'south': 48.8, 'east': 2.4, 'west': 2.3}
+)
+
+# Or set predefined location
+optimizer.set_location('tokyo')
+```
+
+### Custom Configuration
+```python
+# Modify fleet configuration
+optimizer.config.num_vehicles = 100
+optimizer.config.vehicle_capacity = 6

+optimizer.config.ai_optimization_enabled = True
+```
+
+### Analytics Integration
+```python
+from fleet_analytics import FleetAnalytics
+
+# Create analytics instance
+analytics = FleetAnalytics()
+
+# Log performance metrics
+metrics = analytics.calculate_performance_metrics(vehicles, demands, stats, weather, traffic)
+analytics.log_performance_metrics(metrics)
+
+# Get session summary
+summary = analytics.get_session_summary()
+print(summary)
+```

+RETAIL ANALYTICS KNOWLEDGE BASE
+
+SALES FORECASTING BEST PRACTICES:
+1. Seasonal Patterns: Most retail businesses experience seasonal fluctuations. Electronics sales peak during holiday seasons (November-December) and back-to-school periods (August-September). Clothing sales follow fashion seasons with spring/summer and fall/winter collections.
+
+2. Trend Analysis: Use moving averages to identify underlying trends. Short-term trends (7-14 days) help with immediate inventory decisions, while long-term trends (30-90 days) inform strategic planning.
+
+3. Anomaly Detection: Sales anomalies can be caused by:
+   - Promotional events and marketing campaigns
+   - External factors (weather, holidays, economic events)
+   - Supply chain disruptions
+   - Competitive actions
+   - Product lifecycle changes
+
+INVENTORY MANAGEMENT GUIDELINES:
+1. Safety Stock Calculation: Safety stock = (Maximum daily usage × Maximum lead time) - (Average daily usage × Average lead time)
+
+2. Reorder Point Formula: Reorder Point = (Average daily usage × Lead time) + Safety stock
+
+3. Economic Order Quantity (EOQ): EOQ = √((2 × Annual demand × Order cost) / Holding cost per unit)
+
+4. ABC Analysis: 
+   - A items: 20% of products, 80% of sales (high priority)
+   - B items: 30% of products, 15% of sales (medium priority)
+   - C items: 50% of products, 5% of sales (low priority)
+
+RETAIL METRICS AND KPIs:
+1. Sales Metrics:
+   - Total Sales Revenue
+   - Sales Growth Rate
+   - Average Transaction Value
+   - Sales per Square Foot
+   - Conversion Rate
+
+2. Inventory Metrics:
+   - Inventory Turnover Rate
+   - Days Sales of Inventory (DSI)
+   - Stockout Rate
+   - Carrying Cost
+   - Order Fill Rate
+
+3. Customer Metrics:
+   - Customer Acquisition Cost (CAC)
+   - Customer Lifetime Value (CLV)
+   - Customer Retention Rate
+   - Net Promoter Score (NPS)
+
+SEASONAL PATTERNS BY CATEGORY:
+1. Electronics:
+   - Peak: Holiday season (Nov-Dec), Back-to-school (Aug-Sep)
+   - Low: January-February (post-holiday)
+   - Factors: New product releases, technology trends
+
+2. Clothing:
+   - Peak: Fashion seasons (Spring/Summer, Fall/Winter)
+   - Low: End of season clearance periods
+   - Factors: Fashion trends, weather patterns
+
+3. Home & Garden:
+   - Peak: Spring (March-May), Summer (June-August)
+   - Low: Winter months (December-February)
+   - Factors: Home improvement projects, gardening seasons
+
+ANOMALY DETECTION METHODS:
+1. Statistical Methods:
+   - Z-score analysis (detects values > 2 standard deviations from mean)
+   - Moving average with control limits
+   - Seasonal decomposition
+
+2. Machine Learning Approaches:
+   - Isolation Forest
+   - One-Class SVM
+   - Autoencoders
+   - LSTM-based anomaly detection
+
+3. Business Rule-Based:
+   - Percentage change thresholds
+   - Day-of-week comparisons
+   - Holiday adjustments
+
+FORECASTING MODELS:
+1. Time Series Models:
+   - Prophet: Good for seasonal patterns and trend changes
+   - ARIMA: Effective for stationary time series
+   - Exponential Smoothing: Simple but effective for short-term forecasts
+
+2. Machine Learning Models:
+   - Random Forest: Good for capturing non-linear relationships
+   - XGBoost: Effective for complex patterns
+   - LSTM: Excellent for long-term dependencies
+
+3. Ensemble Methods:
+   - Combine multiple models for better accuracy
+   - Weighted averaging based on historical performance
+   - Model selection based on data characteristics
+
+BUSINESS INTELLIGENCE INSIGHTS:
+1. Store Performance Analysis:
+   - Compare stores within same region
+   - Identify top and bottom performers
+   - Analyze regional differences
+   - Assess store-specific factors (location, size, demographics)
+
+2. Product Performance:
+   - Identify best and worst selling products
+   - Analyze product lifecycle stages
+   - Cross-selling opportunities
+   - Product cannibalization effects
+
+3. Customer Behavior:
+   - Purchase patterns and preferences
+   - Seasonal buying behavior
+   - Price sensitivity analysis
+   - Customer segmentation
+
+RECOMMENDATION STRATEGIES:
+1. Inventory Optimization:
+   - Right-size inventory based on demand forecasts
+   - Implement just-in-time (JIT) for fast-moving items
+   - Use vendor-managed inventory (VMI) for strategic partnerships
+   - Consider consignment inventory for new products
+
+2. Pricing Strategies:
+   - Dynamic pricing based on demand and competition
+   - Promotional pricing for slow-moving inventory
+   - Bundle pricing for complementary products
+   - Seasonal pricing adjustments
+
+3. Marketing Optimization:
+   - Target promotions based on customer segments
+   - Optimize timing of marketing campaigns
+   - Personalize offers based on purchase history
+   - A/B test different promotional strategies
+
+RISK MANAGEMENT:
+1. Supply Chain Risks:
+   - Supplier diversification
+   - Safety stock for critical items
+   - Alternative sourcing options
+   - Lead time variability management
+
+2. Demand Risks:
+   - Scenario planning for demand fluctuations
+   - Flexible inventory policies
+   - Quick response capabilities
+   - Demand sensing technologies
+
+3. Financial Risks:
+   - Cash flow management
+   - Working capital optimization
+   - Cost control measures
+   - Profit margin protection
+
+TECHNOLOGY TRENDS IN RETAIL:
+1. AI and Machine Learning:
+   - Predictive analytics for demand forecasting
+   - Computer vision for inventory tracking
+   - Natural language processing for customer service
+   - Recommendation engines for personalization
+
+2. IoT and Automation:
+   - RFID for real-time inventory tracking
+   - Automated reordering systems
+   - Smart shelves with sensors
+   - Robotics for warehouse operations
+
+3. Data Analytics:
+   - Real-time dashboards
+   - Advanced reporting capabilities
+   - Data visualization tools
+   - Integration with business systems

+            As an AI fleet optimization expert, provide specific, actionable recommendations for:
+            
+            1. VEHICLE ALLOCATION STRATEGY:
+               - How should I prioritize vehicle assignments?
+               - Which vehicles should handle high-priority demands?
+               - How to balance utilization vs. response time?
+            
+            2. DEMAND PRIORITIZATION:
+               - How to handle {len(high_priority_demands)} high-priority demands?
+               - Should I focus on revenue or customer satisfaction?
+               - How to manage peak vs. off-peak periods?
+            
+            3. ROUTE OPTIMIZATION:
+               - How to minimize travel time and costs?
+               - How to account for current weather/traffic conditions?
+               - Should I use predictive routing?
+            
+            4. PERFORMANCE IMPROVEMENTS:
+               - How to increase utilization from {utilization_rate:.1f}%?
+               - How to improve revenue per vehicle (currently ${avg_earnings_per_vehicle:.2f})?
+               - What operational changes would you recommend?
+            
+            Please provide specific, actionable recommendations with reasoning.
