Effective inventory management is essential for optimizing operational efficiency and minimizing costs within supply chain and inventory systems. The core concept often employed in analyzing inventory costs is the Economic Order Quantity (EOQ), which balances ordering costs and holding costs to determine the most cost-effective order size. This paper explores several scenarios involving inventory calculations, emphasizing the importance of EOQ and related metrics such as average inventory, total costs, and order frequency.

The first scenario presents a company with an order quantity of 10,000 units, an average inventory of 35,000 units, and four orders per year. The carrying cost per unit per year is $0.35, and the ordering cost per order is $500. The total annual inventory cost amounts to $3,500, with an optimal time between orders of approximately 91 days. This scenario demonstrates a straightforward application of EOQ principles, where the balance of ordering and carrying costs has been achieved, resulting in a relatively low total cost and manageable order frequency.

The second case outlines a different inventory system with a much larger order quantity of approximately 190,919 units, an average inventory of 1,215,000 units, and six orders annually. The carrying cost is reduced to $0.08 per unit, and ordering costs increase to $1,200 per order, leading to a total annual cost of around $15,274. The optimal ordering interval is about 61 days. The significant increase in order size and decrease in carrying cost highlight how adjustments in cost parameters impact EOQ and overall expenditure, emphasizing the importance of tailored inventory strategies based on specific cost structures.

Further analysis involves a scenario with a smaller order quantity of 456 units and an average inventory of 2,000 units, with no explicit number of orders provided. The carrying cost per unit is notably high at $50, and ordering costs are $2,600, with the total inventory cost reaching nearly $22,803.3. The demand per day is 2,000 units, and the reorder point is approximately 64.5 units. This case underscores the consequences of high carrying costs, which make holding inventory expensive, and suggests the necessity of careful calculation to determine optimal order quantity to minimize total costs while ensuring adequate inventory levels.

Additionally, the scenarios exemplify the use of EOQ formulas in varying contexts, including calculating average inventory (Q/2), the number of orders per year, and the optimal time between orders. These calculations are critical in designing effective replenishment policies that align with demand rates, cost considerations, and operational constraints. Understanding these parameters helps firms in strategic planning, reducing operational costs, and improving service levels by avoiding stockouts or excess inventory.

In conclusion, inventory management involves balancing various costs to determine optimal order quantities that minimize total expenses while meeting customer demand. The EOQ model provides a foundational framework for such analysis, and understanding its application across different scenarios enables managers to develop efficient supply chain strategies. Properly managing inventory costs contributes to improved profitability, customer satisfaction, and supply chain resilience.
