+- **Supplier Integration**: Close partnerships for reliable, frequent deliveries
+- **Quality Focus**: Defect-free materials to prevent production disruptions
+
+### Implementation Requirements
+- **Reliable Suppliers**: Certified vendors with consistent quality
+- **Stable Production Schedule**: Level production to enable predictable material flows
+- **Short Setup Times**: Quick changeovers to support small batch production
+- **Preventive Maintenance**: Equipment reliability to maintain flow
+
+### JIT Benefits for Manufacturing
+- **Reduced Carrying Costs**: 50-80% reduction in inventory investment
+- **Improved Cash Flow**: Faster inventory turns and reduced working capital

+- **Two-Bin System**: One in use, one in reserve/replenishment
+- **Pull Authorization**: Material moved only when signaled
+- **Continuous Flow**: Smooth material movement through production
+
+### Kanban Calculation Formula
+```
+Number of Kanbans = (Demand during Lead Time + Safety Stock) / Container Quantity
+
+Where:
+- Demand during Lead Time = Daily Demand × Lead Time (days)
+- Safety Stock = Buffer for demand/supply variability
+- Container Quantity = Standard batch size
+```
+

+## Advanced Inventory Management Techniques
+
+### ABC-XYZ Analysis
+- **ABC Classification**: Value-based (A=high value, B=medium, C=low)
+- **XYZ Classification**: Demand variability (X=stable, Y=variable, Z=irregular)
+- **Strategic Matrix**: 9-category classification for tailored management
+
+### Demand Forecasting Methods
+- **Moving Averages**: Simple smoothing for stable demand
+- **Exponential Smoothing**: Weighted recent data for trending demand
+- **Seasonal Decomposition**: Account for cyclical patterns
+- **Machine Learning**: AI-driven forecasting for complex patterns
+
+### Safety Stock Optimization
+```
+Safety Stock = Z-score × √(Lead Time) × Standard Deviation of Demand
+
+Where:
+- Z-score = Service level factor (1.65 for 95% service level)
+- Lead Time = Supplier lead time in days
+- Standard Deviation = Historical demand variability
+```
