Question 1

Which type of plant layout groups machinery and equipment by the type of function or operation performed, regardless of the product?

Accepted Answer

Process (functional) layout

Answer

A process layout arranges equipment by function (e.g., all drilling machines in one area), which suits high-variety, low-volume production but increases material handling distances.

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

The bullwhip effect occurs because each upstream tier in the supply chain over-reacts to downstream demand signals, causing progressively larger order swings — like the tip of a whip amplifying small wrist movements.

Question 3

In assembly line balancing, line efficiency is calculated as:

Accepted Answer

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

Answer

Line efficiency = Total task time / (Cycle time × Number of workstations), expressing the fraction of available workstation time that is productively used.

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

JIT is a pull-based philosophy originating from Toyota that produces the right item, at the right time, in the right quantity — treating inventory as waste to be eliminated.

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

Work sampling uses statistical random observations to estimate the percentage of time workers or machines spend in various states, without the need for continuous stopwatch observation.
