Sample Problem and Step-by-Step Solution

Problem Statement

A manufacturing company needs to determine the optimal order quantity for raw materials. The annual demand is 12,000 units. The ordering cost per order is $50, and the holding cost per unit per year is $2. Calculate the Economic Order Quantity (EOQ).

Solution Approach

Step 1: Recall the EOQ formula:

\[ EOQ = \sqrt{\frac{2DS}{H}} \]

where:

• D = annual demand
• S = ordering cost per order
• H = holding cost per unit per year

Step 2: Plug in the known values:

• D = 12,000 units
• S = $50
• H = $2

\[ EOQ = \sqrt{\frac{2 \times 12000 \times 50}{2}} \]

Step 3: Calculate numerator:

\[ 2 \times 12000 \times 50 = 1,200,000 \]

Step 4: Divide by holding cost:

\[ \frac{1,200,000}{2} = 600,000 \]

Step 5: Take the square root:

\[ EOQ = \sqrt{600,000} \approx 774.6 \]

Final answer: The optimal order quantity is approximately 775 units.

Sample Problem and Step-by-Step Solution

Problem:

A company faces an annual demand of 12,000 units for a product. The ordering cost per order is $50, and the holding cost per unit per year is $2. Determine the EOQ, the number of orders per year, and the total annual inventory cost.

Solution:

Step 1: Identify Data

• D = 12,000 units/year
• S = $50 per order
• H = $2 per unit/year

Step 2: Calculate EOQ

\[ EOQ = \sqrt{\frac{2 \times 12,000 \times 50}{2}} = \sqrt{\frac{1,200,000}{2}} = \sqrt{600,000} \approx 774.6 \]

Step 3: Number of Orders per Year

\[ \text{Number of orders} = \frac{D}{EOQ} = \frac{12,000}{774.6} \approx 15.5 \text{ orders} \]

Step 4: Total Inventory Cost

• Ordering costs: \(15.5 \times \$50 = \$775\)
• Holding costs: \(\frac{EOQ}{2} \times H = \frac{774.6}{2} \times 2 = 387.3 \times 2 = \$774.6\)
• Total cost: \$775 + \$774.6 ≈ \$1,549.60

Interpretation:

The company should order approximately 775 units each time, placing around 16 orders annually, with total inventory-related costs around \$1,550.
