,Q1. A multinational electronics firm is redesigning its supply chain to be more
resilient. They are considering a multi-sourcing strategy for critical components, but
they are concerned about the potential loss of economies of scale. Which approach
best mitigates this trade-off while maintaining resilience?
A. Single-sourcing with high inventory buffers
B. Dual-sourcing with one primary and one backup supplier
C. Multi-sourcing across many suppliers with no volume guarantees
D. Vertical integration of all component manufacturing
Correct Answer: B. Dual-sourcing with one primary and one backup supplier
Rationale: Dual-sourcing with a primary and backup supplier balances resilience with
scale economies: the primary supplier receives high volumes (maintaining scale), while
the backup is used for risk mitigation. Single-sourcing lacks resilience; multi-sourcing
without volume guarantees sacrifices scale economies; vertical integration is costly and
inflexible.
Why Wrong:
A - Single-sourcing creates high dependency and risk despite inventory buffers.
C - Spreading volumes across many suppliers erodes economies of scale and
complicates quality management.
D - Vertical integration reduces flexibility and increases capital investment without
addressing supplier risk.
Reference: Chopra, S. (2019). Supply Chain Management: Strategy, Planning, and
Operation, 7th ed., Ch. 14
Q2. In a multi-echelon inventory system, a retailer and a supplier independently
apply a periodic review policy with different review intervals. The supplier's demand
variability is amplified due to the retailer's ordering pattern. Which of the following
is the most effective strategy to mitigate the bullwhip effect in this scenario?
A. Increase the retailer's order batch size to achieve transportation economies
B. Implement a vendor-managed inventory (VMI) system with shared demand data
C. Shorten the supplier's review interval without altering the retailer's policy
D. Introduce price promotions to stimulate demand during slow periods
Correct Answer: B. Implement a vendor-managed inventory (VMI) system with
shared demand data
Rationale: VMI shifts ordering responsibility to the supplier, using actual demand data
rather than retailer orders, which eliminates the demand signal distortion that causes the
bullwhip effect. Increasing batch sizes amplifies variability; shortening review intervals
alone doesn't fix the root cause; price promotions artificially inflate demand variability.
Why Wrong:
A - Larger batch sizes increase order variance and worsen the bullwhip effect.
Page 3
, C - Adjusting review intervals without addressing information distortion has limited
impact.
D - Promotions induce demand spikes that further distort orders.
Reference: Lee, H.L., Padmanabhan, V., & Whang, S. (1997). The Bullwhip Effect in
Supply Chains. Sloan Management Review
Q3. A supply chain manager is evaluating a new supplier's financial stability. Which
financial metric is most directly indicative of the supplier's ability to meet short-term
obligations without relying on inventory liquidation?
A. Current ratio
B. Quick ratio (acid-test ratio)
C. Debt-to-equity ratio
D. Inventory turnover ratio
Correct Answer: B. Quick ratio (acid-test ratio)
Rationale: The quick ratio excludes inventory from current assets, providing a more
conservative measure of liquidity that reflects the supplier's ability to pay short-term
liabilities without selling inventory, which is often illiquid. The current ratio includes
inventory, which may overstate liquidity; debt-to-equity measures long-term solvency;
inventory turnover measures efficiency, not liquidity.
Why Wrong:
A - Current ratio includes inventory, which may not be quickly convertible to cash.
C - Debt-to-equity ratio assesses capital structure, not short-term liquidity.
D - Inventory turnover is an efficiency metric, not a direct liquidity measure.
Reference: Waters, D. (2011). Supply Chain Risk Management: Vulnerability and
Resilience in Logistics, Ch. 6
Q4. A manufacturer uses a continuous review inventory policy. Annual demand is
10,000 units, ordering cost is $100 per order, and holding cost is $2 per unit per year.
Lead time is normally distributed with a mean of 10 days and a standard deviation of
2 days. If the firm targets a 95% service level, what is the reorder point? (Assume 365
days per year and demand is independent of lead time.)
A. Approximately 274 units
B. Approximately 316 units
C. Approximately 337 units
D. Approximately 365 units
Correct Answer: C. Approximately 337 units
Rationale: Daily demand = 10,000/365 "H 27.4 units. Mean lead time demand = 27.4 × 10
= 274. Standard deviation of lead time demand = sqrt(10×27.4^2 + (27.4×2)^2)
sqrt(7507.6 + 3003) sqrt(10510.6) 102.5. Safety stock for 95% (z=1.65) = 1.65×102.5
169. Reorder point = 274 + 169 443 units. None of the options match exactly; the closest
