Which of the following network is Event oriented?
- APERTCorrect
- BCPM
- CBoth (A) and (B)
- DNone of the above
Solution
Concept
Event oriented project network technique
Formula
NONE
Step-by-step solution
1. PERT (Program Evaluation and Review Technique) focuses on milestones or specific points in time. 2. Hence, PERT networks are event-oriented systems where events represent the start or completion of activities. 3. In contrast, CPM (Critical Path Method) is activity-oriented. Answer: A
Explanation
Program Evaluation and Review Technique (PERT) is an event-oriented network technique because its main focus is on the completion of milestones or events rather than individual activities. In a PERT network, nodes represent key events or achievements in the project timeline. Conversely, CPM is an activity-oriented network technique focused primarily on activity durations and costs.
Why the other options are wrong
B) CPM (Critical Path Method) is an activity-oriented network technique, not event-oriented. C) Both are not event-oriented because CPM focuses on activities while PERT focuses on events. D) Option A is correct as PERT is specifically an event-oriented network model.
Shortcut
PERT is Event-oriented, while CPM is Activity-oriented.
Common mistake
Confusing PERT, which is event-oriented, with CPM, which is activity-oriented.
Correct answer: A) PERT
