Study Notes
Inventory Management
Inventory management is a crucial aspect of logistics and supply chain engineering, as it involves the planning, coordination, and control of inventory levels to meet customer demand while minimizing costs.
Key Concepts:
- Inventory: The stock of goods or materials held by a company to meet customer demand or support production.
- Inventory management: The process of managing inventory levels, including forecasting, ordering, and stocking decisions.
- Inventory costs: The costs associated with holding inventory, including storage, handling, and maintenance costs.
Inventory Management Objectives:
- Minimize inventory costs: Reduce inventory holding costs while maintaining sufficient stock levels to meet customer demand.
- Maximize service level: Ensure that customer demand is met on time and in full.
- Optimize inventory levels: Balance inventory levels to avoid stockouts and overstocking.
Inventory Management Strategies:
- Just-in-Time (JIT) inventory system: Maintain minimal inventory levels and order supplies just in time to meet customer demand.
- Economic Order Quantity (EOQ) model: Calculate the optimal order quantity to minimize total inventory costs.
- ABC analysis: Classify inventory into three categories based on value and importance: A (high value, high importance), B (medium value, medium importance), and C (low value, low importance).
Inventory Management Techniques:
- Forecasting: Use historical data and statistical methods to predict future demand.
- Lead time management: Manage the time between ordering and receiving inventory to minimize stockouts and overstocking.
- Buffer stock management: Maintain a safety stock to protect against stockouts and uncertainties.
Inventory Management Performance Metrics:
- Inventory turnover: The number of times inventory is sold and replaced during a period.
- Inventory days supply: The number of days inventory will last at current sales rates.
- Fill rate: The percentage of customer demand that is met from existing inventory.
These notes provide a concise overview of the key concepts, objectives, strategies, techniques, and performance metrics involved in inventory management, a critical aspect of logistics and supply chain engineering.
