Economic Order Quantity (EOQ) is a powerful tool that businesses can use to minimize inventory costs and streamline their supply chain operations. EOQ takes into account various factors, such as carrying costs, ordering costs, and demand variables, to determine the optimal order quantity. Here's how businesses can utilize EOQ to minimize costs:

1. Calculate EOQ: The first step is to calculate the EOQ using the EOQ formula, which is:

EOQ = sqrt((2 * D * S) / H)

Where:

- D represents the annual demand for the product

-'s represents the ordering cost per order

- H represents the holding cost per unit per year

2. Consider Reorder Point: Once the EOQ is determined, businesses should also calculate the reorder point (ROP) to ensure timely replenishment of inventory. The ROP is the inventory level at which a new order should be placed to avoid stockouts.

3. Optimize Order Frequency: By using EOQ, businesses can optimize their order frequency to reduce ordering costs. EOQ helps determine the optimal order size, ensuring that businesses do not place orders too frequently or in excessive quantities.

4. minimize Carrying costs: EOQ also helps minimize carrying costs by ensuring that inventory levels are optimized. Carrying costs include expenses such as storage costs, obsolescence costs, and the cost of capital tied up in inventory. By reducing excess inventory, businesses can minimize carrying costs and improve overall cost efficiency.

Using EOQ as a guiding principle in inventory management enables businesses to strike a balance between ordering costs and carrying costs, ultimately minimizing overall inventory costs and improving profitability.
