Inventory Management in Action: Business Examples for Students

📚 Quick Study Guide

• 📦 Inventory Management: Overseeing the flow of goods, from raw materials to finished products.
• 💰 Economic Order Quantity (EOQ): A formula to determine the optimal order size to minimize total inventory costs. Formula: $EOQ = \sqrt{\frac{2DS}{H}}$, where $D$ is annual demand, $S$ is ordering cost, and $H$ is holding cost.
• ⏱️ Just-in-Time (JIT): An inventory strategy to receive goods only when needed, reducing storage costs.
• 📊 ABC Analysis: Categorizing inventory into A (high-value), B (medium-value), and C (low-value) items.
• 📉 Inventory Turnover Ratio: Measures how many times inventory is sold and replaced over a period. Formula: $Inventory Turnover = \frac{Cost of Goods Sold}{Average Inventory}$.
• 🛡️ Safety Stock: Extra inventory held to mitigate the risk of stockouts due to demand or supply fluctuations.
