Data Source and Methodology
The EOQ calculation is based on the classic economic order quantity formula, widely used in inventory management. All calculations are based on this standard methodology.
The Formula Explained
\( EOQ = \sqrt{\frac{2DS}{H}} \)
Where \( D \) is the annual demand, \( S \) is the order cost, and \( H \) is the holding cost per unit per year.
Glossary of Variables
- Annual Demand (D): The total number of units required per year.
- Order Cost (S): The fixed cost associated with placing an order.
- Holding Cost (H): The cost to hold a single unit in inventory for a year.
- EOQ: The optimal order quantity that minimizes total inventory costs.
How It Works: A Step-by-Step Example
Consider a company with an annual demand of 1000 units, an order cost of $50 per order, and a holding cost of $2 per unit per year. Plug these values into the EOQ formula to find the optimal order quantity:
\( EOQ = \sqrt{\frac{2 \times 1000 \times 50}{2}} = \sqrt{50000} = 223.61 \)
Therefore, the company should order approximately 224 units per order to minimize costs.
Frequently Asked Questions (FAQ)
What is Economic Order Quantity (EOQ)?
EOQ is a calculation used to determine the most efficient order quantity that minimizes the total costs of inventory, including holding and ordering costs.
Why is EOQ important?
EOQ helps businesses reduce inventory costs by balancing order frequency and storage costs.
How often should I recalculate EOQ?
EOQ should be recalculated whenever there are significant changes in demand, order costs, or holding costs.
Can EOQ be used for all types of products?
EOQ is best suited for products with consistent demand and stable cost structures. It may not be suitable for perishable or highly seasonal products.
Is EOQ applicable in service industries?
EOQ is primarily used in manufacturing and retail sectors, but the principles can be adapted for certain service industry scenarios.
