In project planning, the activity durations are calculated by PERT and CPM techniques assuming:
Show Hint
Use PERT when dealing with high uncertainty in project activities. Use CPM when time estimates are well-known and fixed.

The Correct Option is A
Solution and Explanation
PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method) are widely used for project scheduling and management. They differ fundamentally in their assumptions about activity durations:
- PERT assumes activity durations are uncertain and hence adopts a probabilistic approach, using three estimates: optimistic, pessimistic, and most likely.
- CPM, on the other hand, assumes activity durations are certain and follows a deterministic approach, with a single fixed time estimate.

- A double-ended ranging drum (DERD) shearer uni-directionally cuts coal in a longwall panel having the following details:
Shearer drum diameter = 1.4 m
Panel dimension = 1200 m × 200 m × 2.4 m
Web depth = 0.6 m
Average cutting speed = 5 m/minute
Average retreating speed = 10 m/minute
Average operational delay between cuts is 2 hour. There are two production shifts, each of 8 hour duration. The number of days required for complete extraction of the panel is:- GATE MN - 2025

- A longwall panel is to be developed in a flat seam at a depth of \( H \) m. The surface subsidence profile (\( s \)) of the area with the horizontal distance \( x \) is estimated as \[ s = \frac{S_{{max}}}{2} \left[ 1.002 - \tanh \left( \frac{4.8x}{H} \right) \right], \] where \( S_{{max}} \) is the maximum subsidence at the centre of the panel, \( x \) is measured from the inflection point. The value of \( x \) is negative towards the panel centre and positive towards the panel boundary. The ratio between the critical width of the panel and the depth is:
