Network Analysis MCQ with answer and solution

Concept

Deterministic Nature of CPM

Formula

No formula

Step-by-step solution

1. Identify that a deterministic technique assumes activity durations are fixed and known with certainty. 2. Recall that CPM (Critical Path Method) uses a single, fixed time estimate for each activity, unlike PERT which is probabilistic. 3. Match CPM with Option A.

Explanation

Option A (CPM or Critical Path Method) is deterministic because it uses single, fixed time estimates for each activity, assuming that task durations are known with certainty and do not vary. Unlike PERT, which is probabilistic and accounts for uncertainty using multiple time estimates, CPM relies on definite, predictable timeframes.

Shortcut

Remember "CPM is Certain" (Deterministic, single fixed time) and "PERT is Probabilistic" (uses three time estimates).

Common mistake

Many students confuse CPM with PERT and select PERT (Option B) because both are widely taught together, forgetting that PERT is probabilistic (uses three time estimates) while CPM is deterministic (uses a single fixed time estimate).
