,Q1. A multinational manufacturer seeks to redesign its distribution network to
balance service and cost. Which modeling approach best captures the trade-off
between facility costs, transportation costs, and customer response times while
accounting for probabilistic demand?
A. Deterministic mixed-integer linear programming with fixed facility costs
B. Stochastic programming with scenario-based demand realizations
C. Simulation optimization using discrete-event simulation
D. Heuristic clustering (e.g., k-means) to assign customers to warehouses
Correct Answer: B. Stochastic programming with scenario-based demand
realizations
Rationale: Stochastic programming explicitly incorporates probabilistic demand via
scenarios, enabling optimization of facility location and allocation under uncertainty.
Deterministic MILP ignores uncertainty, simulation may not optimize directly, and
heuristics lack optimality guarantees.
Why Wrong:
A - Deterministic MILP fails to capture demand uncertainty, potentially leading to
suboptimal network design under variable demand.
C - Simulation evaluates performance but does not directly optimize facility decisions,
requiring extensive scenario testing.
D - Clustering heuristics ignore costs and service constraints, yielding cost-inefficient
allocations.

Operation, 7th ed., Ch. 5
Q2. In a periodic review inventory system with a target order-up-to level, demand
follows a normal distribution with mean 100 units/week and standard deviation 20
units/week. Lead time is 2 weeks, review period is 1 week, and desired cycle service
level is 95%. What is the required safety stock?
A. 33 units
B. 47 units
C. 58 units
D. 66 units
Correct Answer: C. 58 units
Rationale: For periodic review, demand during review period + lead time has standard
deviation (R+L) = 20(1+2) = 203 34.64. Safety stock = z × (R+L) = 1.645 × 34.64 57.0,
so 58 units.
Why Wrong:
A - 33 units uses z=0.95 instead of 1.645, underestimating the required safety stock.
B - 47 units arises from using (L) only, ignoring review period variability.
Page 3
, D - 66 units incorrectly applies z=1.96 (98% service level) or uses (R+L) with R=2.

Supply Chains, 4th ed., Ch. 7
Q3. A firm has two suppliers: Supplier A has a 2% probability of disruption per
period, Supplier B has 5%, but they are positively correlated (correlation coefficient
0.3). Which risk mitigation strategy most effectively reduces the probability of
simultaneous disruption?
A. Increase order allocation to Supplier A to 90%
B. Use dual sourcing with negatively correlated suppliers
C. Hold higher safety stock for all components
D. Insource production of critical components
Correct Answer: B. Use dual sourcing with negatively correlated suppliers
Rationale: Dual sourcing with negatively correlated suppliers reduces the chance that
both fail simultaneously, as disruptions are less likely to coincide. Positive correlation
increases simultaneous risk. The other options do not directly lower the joint probability of
disruption.
Why Wrong:
A - Concentrating orders increases dependence on one supplier, raising overall
disruption risk.
C - Safety stock mitigates impact but does not reduce the probability of simultaneous
disruption.
D - Insourcing may reduce supplier risk but does not address correlated supplier
failures.

Managing Supply Chain Disruption Risks. Management Science.
Q4. Which statement best reflects the relationship between the bullwhip effect and
information sharing in a multi-echelon supply chain?
A. Sharing real-time point-of-sale data eliminates the bullwhip effect entirely.
B. The bullwhip effect is primarily caused by demand forecasting; information sharing
only mitigates, not eliminates, it.
C. The bullwhip effect arises only when orders are batched; information sharing has no
impact on batching.
D. Information sharing amplifies the bullwhip effect because it reveals demand
variability to all echelons.
Correct Answer: B. The bullwhip effect is primarily caused by demand forecasting;
information sharing only mitigates, not eliminates, it.
