Inventory Optimizer
Overview
The Inventory Optimizer provides comprehensive inventory optimization capabilities including segmentation, service level targeting, and multi-echelon optimization. It balances inventory investment against service levels to maximize supply chain performance.
Capabilities
- ABC/XYZ Inventory Classification: Segment by value and demand variability
- Service Level to Inventory Tradeoff: Model cost-service curves
- Multi-Echelon Inventory Optimization: Optimize across network tiers
- Safety Stock Calculation: Demand and lead time variability-based
- Reorder Point and EOQ Optimization: Economic order quantity analysis
- Slow-Moving/Obsolete Identification: SLOB analysis and disposition
- Inventory Investment Optimization: Working capital optimization
- Network Inventory Rebalancing: Cross-location optimization

Usage
ABC/XYZ Segmentation
Input: SKU master with annual usage and demand history
Process: Calculate value classification (ABC) and variability (XYZ)
Output: Nine-box segmentation with policy recommendations
Safety Stock Optimization
Input: Demand variability, lead time variability, service targets
Process: Calculate optimal safety stock by segment
Output: Safety stock quantities with investment impact
Network Inventory Balance
Input: Multi-location inventory positions, demand by location
Process: Identify imbalances and rebalancing opportunities
Output: Transfer recommendations with cost savings
Integration Points
- ERP Systems: Inventory data, transactions, master data
- Planning Systems: Demand forecasts, supply plans
- Optimization Solvers: scipy, CPLEX, Gurobi
- Tools/Libraries: scipy optimization, inventory algorithms
Process Dependencies
- Inventory Optimization and Segmentation
- Safety Stock Calculation and Optimization
- Demand-Driven Material Requirements Planning (DDMRP)
Best Practices
- Refresh segmentation quarterly
- Validate demand variability calculations
- Consider service differentiation by customer segment
- Monitor fill rate vs. inventory investment tradeoffs
- Establish SLOB review cadence
- Document policy rationale for auditing
