Accepted Answer

Process (functional) layout

Answer

Product (line) layout

Answer

Fixed-position layout

Answer

Cellular (group technology) layout

Question 2

The 'bullwhip effect' in supply chain management describes:

Accepted Answer

The amplification of demand variability as orders move upstream from retailer to manufacturer to supplier

Answer

Supply chain collapse caused by major economic recessions

Answer

Cyclical price swings in commodity markets affecting raw material costs

Answer

Disruptions caused by extreme weather events on logistics networks

Question 3

In assembly line balancing, line efficiency is calculated as:

Accepted Answer

Total task time / (Cycle time × Number of workstations)

Answer

Cycle time × Number of workstations / Total task time

Answer

Number of workstations / Total task time

Answer

Total task time × Cycle time × Number of workstations

Question 4

Just-In-Time (JIT) manufacturing primarily aims to:

Accepted Answer

Produce items only when needed, in the quantity needed, eliminating waste from excess inventory

Answer

Maximize inventory buffers at every stage to prevent production stoppages

Answer

Reduce machine downtime by scheduling extensive preventive maintenance windows

Answer

Increase throughput by running all machines at 100% capacity continuously

Question 5

Work sampling differs from traditional time study in that it:

Accepted Answer

Estimates the proportion of time spent on activities through random observations taken at random intervals

Answer

Measures the exact elapsed time for each individual task cycle using a stopwatch

Answer

Calculates ergonomic risk scores for repetitive motion tasks at each workstation

Answer

Determines the optimal machine-to-operator ratio using queuing theory models

Question 6

In the Kanban pull system used in lean manufacturing, a Kanban card or signal serves to:

Accepted Answer

Authorize production or replenishment of a specific quantity of items only when downstream consumption creates a need

Answer

Record worker attendance and individual productivity metrics

Answer

Schedule preventive maintenance and calibration of production equipment

Answer

Document quality defects and assign responsibility for corrective action

Question 7

Ergonomics (human factors engineering) in an industrial engineering context focuses primarily on:

Accepted Answer

Designing work systems, equipment, and environments to match human physical and cognitive capabilities and limitations

Answer

Maximizing machine utilization rates and production throughput speed

Answer

Developing full automation to eliminate manual labor from production processes

Answer

Reducing the unit cost of raw materials through supplier negotiation strategies
