1. An industrial engineer is evaluating a production system consisting of
three sequential workstations. Station A can produce 50 units/hour,
Station B can produce 42 units/hour, and Station C can produce 48
units/hour. Assuming unlimited material availability, no downtime, and
no intermediate storage limitations, what is the maximum sustainable
throughput of the system?
A. 42 units/hour
B. 48 units/hour
C. 50 units/hour
D. 140 units/hour
Answer: A. 42 units/hour
Rationale: The throughput of a serial production system is constrained
by its bottleneck, which is the station with the lowest capacity. Station
B can process only 42 units/hour, so the entire system cannot
sustainably produce more than 42 units/hour. Increasing the capacity
of Stations A or C without addressing Station B would not increase
overall throughput.
2. An industrial engineer develops a process flow diagram to identify
where delays occur in a hospital's patient-admission process. Which
1
,analytical tool would be most appropriate for identifying the relative
frequency of different delay causes after the data have been collected?
A. Fishbone diagram
B. Pareto chart
C. Affinity diagram
D. Gantt chart
Answer: B. Pareto chart
Rationale: A Pareto chart ranks categories from greatest to least
frequency or impact and typically incorporates a cumulative
percentage curve. It is particularly useful for determining which small
number of causes account for a large proportion of observed problems.
A fishbone diagram is primarily a cause-and-effect brainstorming tool
rather than a frequency-ranking tool.
3. A manufacturing company wants to translate customer requirements
such as "quiet operation," "low maintenance," and "high reliability" into
measurable engineering characteristics. Which methodology is most
appropriate?
A. Critical path method
B. Quality Function Deployment
C. Monte Carlo simulation
D. Economic order quantity
Answer: B. Quality Function Deployment
Rationale: Quality Function Deployment (QFD) systematically
translates the voice of the customer into technical or engineering
requirements. The House of Quality is commonly used to establish
relationships between customer needs and measurable design
characteristics. The objective is to ensure that engineering decisions
remain connected to customer expectations.

,4. A production system contains a machine with a nominal capacity of
100 units/hour. The machine operates only 90% of scheduled time
because of breakdowns and setups. When operating, it produces
acceptable product at a 95% quality rate. What is the effective output
rate?
A. 85.5 units/hour
B. 90.0 units/hour
C. 95.0 units/hour
D. 105.6 units/hour
Answer: A. 85.5 units/hour
Rationale: Effective output is calculated as nominal capacity
multiplied by availability and quality. Therefore, effective output = 100
× 0.90 × 0.95 = 85.5 units/hour. This illustrates why capacity analysis
must distinguish theoretical capacity from actual productive output.
5. A process contains four independent sequential activities with
reliabilities of 0.98, 0.97, 0.95, and 0.99. Assuming failure of any
activity causes system failure, what is the approximate overall
reliability?
A. 0.894
B. 0.903
C. 0.922
D. 0.970
Answer: A. 0.894
Rationale: For independent components arranged in series, system
reliability equals the product of individual reliabilities. Thus, R = 0.98
× 0.97 × 0.95 × 0.99 ≈ 0.894. Series systems become less reliable as
additional failure-dependent components are added.

, 6. A company is evaluating a proposed automated material-handling
system. The existing process requires operators to move material
manually. Which approach most directly determines whether the
proposed automation provides sufficient economic value relative to its
additional cost?
A. Value engineering
B. Value analysis
C. Break-even analysis
D. Random sampling
Answer: C. Break-even analysis
Rationale: Break-even analysis determines the volume or operating
condition at which the economic benefits of an alternative equal its
costs. For an automation decision, the engineer can compare the
additional fixed investment with labor savings and other variable
savings to determine the required production volume or payback
condition.
7. In a system model, changing an input parameter from 100 to 110
causes the predicted output to change from 500 to 520. Which concept
describes the investigation of how output responds to changes in input
assumptions?
A. Sensitivity analysis
B. Validation
C. Verification
D. Calibration
Answer: A. Sensitivity analysis
Rationale: Sensitivity analysis examines how changes in input
parameters affect model outputs. It is useful for identifying variables
