1. Introduction to Inventory Management
Inventory management in global supply chains involves the supervision and control of the ordering, storage, and use of components that a company uses in the production of the items it sells. Effective inventory management is crucial for maintaining operational efficiency and meeting customer demands in international trade.
Key Concept: Types of Inventory
- Raw Materials
- Work-in-Progress (WIP)
- Finished Goods
- Maintenance, Repair, and Operating (MRO) Supplies
2. Importance of Inventory Management in Global Supply Chains
- Cost Reduction: Minimizes holding costs and prevents overstocking
- Customer Satisfaction: Ensures product availability and timely delivery
- Cash Flow Management: Optimizes working capital
- Risk Mitigation: Helps manage supply chain disruptions
- Forecasting: Improves demand prediction and production planning
3. Inventory Management Techniques
3.1 Just-in-Time (JIT) Inventory
JIT aims to reduce inventory holding costs by receiving goods only as they are needed in the production process.
3.2 Economic Order Quantity (EOQ)
EOQ is a calculation used to determine the optimal quantity of inventory to order to minimize total inventory costs.

3.3 ABC Analysis
ABC analysis categorizes inventory items based on their importance and value to the company.
3.4 Safety Stock
Safety stock is additional inventory kept on hand to prevent stockouts due to uncertainties in supply and demand.
4. Challenges in Global Inventory Management
- Long Lead Times: International shipping can result in extended lead times

Modern inventory management relies heavily on technology:
- Enterprise Resource Planning (ERP) Systems
- Warehouse Management Systems (WMS)
- Radio-Frequency Identification (RFID)
- Artificial Intelligence for Demand Forecasting
- Internet of Things (IoT) for Real-Time Tracking
6. Key Performance Indicators (KPIs) for Inventory Management
- Inventory Turnover Ratio
- Days Sales of Inventory (DSI)
- Stock-to-Sales Ratio
- Carrying Cost of Inventory
- Order Fill Rate
