Step 1: Understanding the Concept:
Economic Order Quantity (EOQ) is an inventory management formula that determines the ideal order size a company should purchase to minimize inventory costs.
Step 2: Key Formula or Approach:
The EOQ is calculated as:
\[ EOQ = \sqrt{\frac{2DS}{H}} \]
where:
\(D\) = Annual demand (units)
\(S\) = Cost per order (ordering cost)
\(H\) = Holding/Carrying cost per unit per year
Step 3: Detailed Explanation:
1. Ordering Cost: The cost associated with placing an order (paperwork, inspection, transport). This decreases as order size increases (fewer orders).
2. Carrying Cost: The cost of holding inventory (storage, insurance, capital tied up). This increases as order size increases.
3. The Goal: EOQ finds the "sweet spot" where the sum of these two opposing costs is at its minimum.
Step 4: Final Answer:
EOQ is specifically designed to balance and minimize the total expenditure related to both the procurement (ordering) and storage (carrying) of inventory.
