BSIE Bachelor of Science in Industrial Engineering MCQ 4

Question 1

The critical path in a project network is defined as the path that:

Accepted Answer

Has zero total float and determines project duration

Answer

The critical path has zero float (slack), meaning any delay on it directly delays the project completion date.

Question 2

In the Transportation Problem of linear programming, a basic feasible solution has exactly m + n - 1 basic variables, where m and n are the number of:

Accepted Answer

Sources and destinations

Answer

A non-degenerate transportation BFS has exactly m + n - 1 allocations, where m = number of sources and n = number of destinations.

Question 3

In human factors engineering, the 'signal detection theory' concept of d-prime (d') measures:

Accepted Answer

The discriminability between signal and noise

Answer

d' quantifies how well an observer can distinguish a signal from background noise, independent of their response bias.

Question 4

Which forecasting method assigns exponentially decreasing weights to older observations and requires only one parameter (α)?

Accepted Answer

Simple exponential smoothing

Answer

Simple exponential smoothing uses a single smoothing parameter α to weight recent data more heavily, with weights declining geometrically for older periods.

Question 5

In failure mode and effects analysis (FMEA), the Risk Priority Number (RPN) is calculated as:

Accepted Answer

Severity × Occurrence × Detection

Answer

RPN = Severity × Occurrence × Detection, producing a number from 1 to 1000 used to prioritize failure modes for corrective action.
