Question 1: Cost Analysis for Supplier Selection
Part A: Calculating the Average Unit Cost from Supplier A for 2,500 Units
For Supplier A, the costs are stratified based on quantity tiers. The first 1,000 units cost $100 each, the next 1,000 units cost $90 each, and the remaining 500 units cost $85 each. To determine the average unit cost, total costs must be calculated first.
Total cost for the first 1,000 units = 1,000 units × $100 = $100,000
Total cost for the next 1,000 units = 1,000 units × $90 = $90,000
Total cost for the remaining 500 units = 500 units × $85 = $42,500
Summing these gives the total expense:
$100,000 + $90,000 + $42,500 = $232,500
Average unit cost:
$232,500 / 2,500 units = $93 per unit
Thus, the average cost when purchasing 2,500 units from Supplier A is $93.
Part B: Comparing Total Costs from Suppliers A and B
Supplier B offers $95 per unit for orders up to 1,500 units and $90 per unit for orders larger than 1,500 units. Since the order is 2,500 units, Supplier B's price is $90 per unit.
Total cost from Supplier B:
2,500 units × $90 = $225,000
Total cost from Supplier A:
$232,500 (from above calculation)
Conclusion: The total cost from Supplier B ($225,000) is lower than from Supplier A ($232,500). Therefore, Supplier B is more economical for this order size.

Question 2: Inventory Management and EOQ Calculation
Part A: Computing EOQ
The EOQ formula:
\[
EOQ = \sqrt{\frac{2DS}{H}}
\]
where:
D = Annual demand = 100,000 units
S = Ordering cost = $50
H = Holding cost per unit = 20% of unit cost = 0.20 × $200 = $40
Plugging in the values:
\[
EOQ = \sqrt{\frac{2 \times 100,000 \times 50}{40}} = \sqrt{\frac{10,000,000}{40}} = \sqrt{250,000} ≈ 500 \text{ units}
\]
Answer: The EOQ is approximately 500 units.
Part B: Total Annual Cost at EOQ
Total cost consists of ordering costs and holding costs:
\[
Total\ Cost = \left(\frac{D}{EOQ}\right) \times S + \frac{EOQ}{2} \times H
\]
Applying the values:
Ordering cost:
\[
\frac{100,000}{500} \times 50 = 200 \times 50 = \$10,000
\]
Holding cost:
\[
\frac{500}{2} \times 40 = 250 \times 40 = \$10,000
\]
Total annual cost:
\$10,000 + \$10,000 = \$20,000
(Sources: Heizer & Render, 2017; Chopra & Meindl, 2016)
Part C: Optimal Order Quantity with Discounted Prices
Discounted prices:
- Up to 400 units: $200/unit
- Larger orders: $180/unit
Calculate EOQ for each price point:
1. For $200/unit (no discount), previously determined as 500 units.
2. For $180/unit, the holding cost changes due to the lower price, assuming it remains at 20% of $180, i.e., $36:
EOQ:
\[
EOQ = \sqrt{\frac{2 \times 100,000 \times 50}{36}} ≈ \sqrt{\frac{10,000,000}{36}} ≈ \sqrt{277,777.78} ≈ 527.05
\]
Since it exceeds 400 units, the optimal order quantity at $180 is better than 400 units.
Comparing costs for:
- 400 units at $200 (not optimal)
- 527 units at $180 (more cost-effective)
Total costs would be:
- For 400 units at $200:
Total cost = (100,000/400) × 50 + (400/2) × (0.2×200) + (unit cost × demand)
But since the unit cost varies, and the main goal is to find the minimal total cost, the EOQ at $180 (≈ 527 units) is preferable than ordering the maximum of 400 units at $200.
Final decision: The EOQ at $180 ($180 per unit) is approximately 527 units, which is optimal compared to 400 units at $200.

Question 3: Assembly Line Task Analysis
Part A: Network Diagram
The task sequence and dependencies are as follows:
- Task A (30s): no predecessor
- Task B (15s): after A
- Task C (20s): after A
- Task D (25s): after B
- Task E (10s): after C and D
- Task F (30s): after D
- Task G (25s): after E and F
The diagram visually represents these tasks connected via arrows, showing dependencies.
Part B: Cycle Time Calculation
Cycle time:
\[
Cycle\ time = \frac{Available\ production\ time\ per\ day}{Required\ units\ per\ day}
\]
Total available time per day:
8 hours × 3600 seconds = 28,800 seconds
Target daily units: 600 units
Cycle time:
\[
\frac{28,800\ seconds}{600\ units} = 48\ seconds/unit
\]
Answer: The cycle time required is 48 seconds.
Part C: Theoretical Minimum Number of Workstations
Using:
\[
Number\ of\ workstations = \lceil \frac{\sum task times}{Cycle\ time} \rceil
\]
Sum of task times:
30 + 15 + 20 + 25 + 10 + 30 + 25 = 155 seconds
Number of workstations:
\[
\lceil \frac{155}{48} \rceil = \lceil 3.23 \rceil = 4
\]
Answer: At least 4 workstations are needed.
Part D: Task Assignment Based on Sequence
Following sequence: A, B, D, C, E, F, G
Assign tasks:
- Workstation 1: A (30s)
- Workstation 2: B (15s), D (25s)
- Workstation 3: C (20s), E (10s)
- Workstation 4: F (30s), G (25s)
Sum of task times per workstation:
- WS1: 30s
- WS2: 40s
- WS3: 30s
- WS4: 55s
All are within the cycle time of 48 seconds, except WS4 slightly exceeds it, indicating the need to adjust task allocation or accept a slightly longer cycle.
Part E: Efficiency Calculation
Efficiency:
\[
E = \frac{\text{Sum of task times}}{\text{Number of workstations} \times \text{Cycle time}}
\]
Sum of task times = 155s
Number of workstations = 4
Cycle time = 48s
Efficiency:
\[
E = \frac{155}{4 \times 48} = \frac{155}{192} ≈ 0.806 \text{ or } 80.6\%
\]
Answer: Approximately 80.6% efficiency.
Part F: Is the efficiency satisfactory?
An efficiency of over 80% generally indicates a well-designed line with minimal idle time, making it acceptable in many manufacturing contexts. However, striving for higher efficiency could reduce idle time further, potentially by balancing the workload more evenly or adjusting task assignments.
