1. A manufacturing facility aims to reduce production bottlenecks. Which
tool is most appropriate for identifying workflow constraints in a
sequential process?
A. Pareto chart
B. Critical path method
C. Value stream mapping
D. Histogram
Answer: C
Value stream mapping visually represents the flow of materials and
information, making it effective for identifying bottlenecks and
inefficiencies in production systems.
2. In time study analysis, the primary purpose of performance rating is
to:
A. Eliminate all delays in work
B. Adjust observed time to normal time
C. Determine machine efficiency only
, D. Calculate inventory levels
Answer: B
Performance rating adjusts the observed time to reflect the speed at
which a worker performs relative to a standard pace, producing
normal time for analysis.
3. Which inventory control model assumes constant demand and
instantaneous replenishment?
A. EOQ model
B. ABC classification
C. FIFO model
D. Just-in-time system
Answer: A
The Economic Order Quantity model assumes constant demand and
immediate replenishment to minimize total inventory costs.
4. A process has four sequential steps with cycle times of 5, 7, 6, and 8
minutes. The bottleneck time is:
A. 5 minutes
B. 6 minutes
C. 7 minutes
D. 8 minutes
Answer: D
The bottleneck is determined by the slowest process step, which in
this case is 8 minutes, limiting overall system throughput.
5. What is the main objective of line balancing in production systems?
A. Increase raw material cost
B. Equalize workload across stations
C. Increase buffer inventory
D. Reduce product variety
Answer: B
, Line balancing aims to distribute work evenly across stations to
minimize idle time and improve production efficiency.
6. Which probability distribution is most appropriate for modeling time
between arrivals in a queueing system?
A. Normal distribution
B. Poisson distribution
C. Exponential distribution
D. Binomial distribution
Answer: C
The exponential distribution models the time between arrivals in a
Poisson process commonly used in queueing theory.
7. In Six Sigma methodology, the DMAIC phase "Measure" primarily
involves:
A. Identifying root causes
B. Implementing solutions
C. Collecting baseline process data
D. Designing new processes
Answer: C
The Measure phase focuses on gathering reliable baseline data to
quantify current process performance.
8. Which chart is best used to monitor process variation over time?
A. Pareto chart
B. Control chart
C. Scatter plot
D. Pie chart
Answer: B
Control charts are used to monitor process stability and detect
variations over time.
