# Supplier Selection Analysis for Engine Orders ## b-1. Calculating Total Cost for Each Supplier **Instructions Recap:** - You must order engines in lot sizes of 1,350 units. - Calculate total cost using full truckload cost rates and lowest feasible unit cost for all calculations. - Round final answers and required lot size for truckload to the nearest whole number. ### Steps to Calculate Total Cost #### **Given Data** - **Annual Requirement:** 16,200 units - **Lot Size:** 1,350 units - **Weight per Engine:** 25 lbs - **Ordering Cost:** $150 per order - **Inventory Carrying Cost:** 20% of average inventory value per year #### **Calculation Steps** 1. **Number of Orders per Year** \[ \text{Number of Orders} = \frac{\text{Annual Requirement}}{\text{Lot Size}} = \frac{16,200}{1,350} \approx 12 \text{ orders per year} \] 2. **Average Inventory** \[ \text{Average Inventory} = \frac{\text{Lot Size}}{2} = \frac{1,350}{2} = 675 \text{ units} \] 3. **Annual Purchasing Cost** - Use *unit price* from each supplier (not provided in image, so assumed to be part of your calculations). 4. **Annual Ordering Cost** \[ \text{Ordering Cost per Year} = \text{Number of Orders} \times \text{Ordering Cost per Order} = 12 \times \$150 = \$1,800 \] 5. **Annual Inventory Carrying Cost** \[ \text{Inventory Carrying Cost} = \text{Average Inventory} \times \text{Unit Price} \times 20\% \] 6. **Total Cost** \[ \text{Total Cost} = \text{Annual Purchasing Cost} + \text{Annual Ordering Cost} + \text{Annual Inventory Carrying Cost} \] #### **Your Calculated Results** - **Supplier 1:** $9,696 - **Supplier 2:** $9,654,880 > **Note:** These values seem to have a major scale difference. If Supplier 2's cost is truly $9,654,880, it is likely a data entry or calculation error versus $9,696. Recheck the unit price and calculation for Supplier 2. --- ## b-2. Would Your Supplier Selection Change? - **Your Answer:** Yes (as Supplier 2 is checked) --- ## Final Summary ### **Summary Table** | Supplier | Total Cost | Selected? | |------------|--------------|-----------| | Supplier 1 | $9,696 | | | Supplier 2 | $9,654,880 | Yes | ### **Conclusion** - The calculation for Supplier 2 indicates a far higher total cost than Supplier 1. - **If these results are accurate, you should select Supplier 1**, as their total cost is dramatically lower. - **However, if there is a calculation or data error,** review the unit price used for Supplier 2 to ensure it is correct. - **Supplier selection should be based on the lowest total cost.** - **With current numbers, Supplier 1 is the clear choice.** --- ## **Recommendation** - **Double-check your calculations, especially for Supplier 2's unit price.** - Select the supplier with the lowest total cost after verifying the data. --- **If you need a re-calculation with correct unit prices or further breakdowns, please provide the unit price for each supplier.** --- **Alt text for image:** A table showing the calculated total cost for Supplier 1 ($9,696) and Supplier 2 ($9,654,880), with Supplier 2 incorrectly selected as the lower cost option.

# Supplier Selection Analysis for Engine Orders ## b-1. Calculating Total Cost for Each Supplier ### Given Data - **Annual Requirement:** 16,200 units - **Lot Size:** 1,350 units - **Weight per Engine:** 25 lbs - **Ordering Cost:** $150 per order - **Inventory Carrying Cost:** 20% of average inventory value per year - **Unit Prices:** - **Supplier 1:** $X per unit - **Supplier 2:** $Y per unit (insert actual unit prices) ### Calculation Steps 1. **Number of Orders per Year** \[ \text{Number of Orders} = \frac{16,200}{1,350} = 12 \text{ orders per year} \] 2. **Average Inventory** \[ \text{Average Inventory} = \frac{1,350}{2} = 675 \text{ units} \] 3. **Annual Purchasing Cost** - For Supplier 1: \[ \text{Purchasing Cost}_{1} = 16,200 \times X \] - For Supplier 2: \[ \text{Purchasing Cost}_{2} = 16,200 \times Y \] 4. **Annual Ordering Cost** \[ \text{Ordering Cost} = 12 \times 150 = \$1,800 \] 5. **Annual Inventory Carrying Cost** - For Supplier 1: \[ \text{Inventory Carrying Cost}_{1} = 675 \times X \times 0.20 \] - For Supplier 2: \[ \text{Inventory Carrying Cost}_{2} = 675 \times Y \times 0.20 \] 6. **Total Cost Calculation** - For Supplier 1: \[ \text{Total Cost}_{1} = \text{Purchasing Cost}_{1} + 1,800 + \text{Inventory Carrying Cost}_{1} \] - For Supplier 2: \[ \text{Total Cost}_{2} = \text{Purchasing Cost}_{2} + 1,800 + \text{Inventory Carrying Cost}_{2} \] ### Example Calculation Assuming: - Supplier 1 unit price \( X = \$100 \) - Supplier 2 unit price \( Y = \$95 \) #### Supplier 1 Calculation 1. **Purchasing Cost:** \[ 16,200 \times 100 = \$1,620,000 \] 2. **Inventory Carrying Cost:** \[ 675 \times 100 \times 0.20 = \$13,500 \] 3. **Total Cost for Supplier 1:** \[ 1,620,000 + 1,800 + 13,500 = \$1,635,300 \] #### Supplier 2 Calculation 1. **Purchasing Cost:** \[ 16,200 \times 95 = \$1,539,000 \] 2. **Inventory Carrying Cost:** \[ 675 \times 95 \times 0.20 = \$12,825 \] 3. **Total Cost for Supplier 2:** \[ 1,539,000 + 1,800 + 12,825 = \$1,553,625 \] ### Final Results - **Supplier 1 Total Cost:** $1,635,300 - **Supplier 2 Total Cost:** $1,553,625 --- ## b-2. Would Your Supplier Selection Change? - **Selected Supplier:** Supplier 2 - **Reason:** Supplier 2 offers a lower total cost. --- ## Final Summary ### Summary Table | Supplier | Total Cost | Selected? | |------------|--------------|-----------| | Supplier 1 | $1,635,300 | No | | Supplier 2 | $1,553,625 | Yes | ### Conclusion - Supplier 2 is the preferable choice based on the total cost analysis. - Ensure to use accurate unit prices for calculations. - Review and confirm all calculations before finalizing the supplier. --- **Note:** Replace \( X \) and \( Y \) with actual unit prices from your data for precise calculations.
