Question 1

IN PERT analysis, the time estimates of activities and probability of their occurrence follow

Question 2

Which one of the following relates to determination of critical path in PERT?

Question 3

Which one of the following techniques is most suitable in case of research and development type of activity?

Question 4

A small project, consists of seven activities in the activity-on-node diagram as shown in the figure below, in days and the predecessor relationships are shown.

What is the total project duration of the project?

Question 5

Consider the following statements pertaining to CPM network analysis:
1) It is event-oriented method.
2) It is activity-oriented method.
3) Time and cost are controlling factors.
4) Time alone is controlling factor.
Which of these statements are correct?

Question 6

Consider the following statements:
1) PERT is activity-oriented and adopts deterministic approach.
2) CPM is event-oriented and adopts probabilistic approach.
3) PERT is event-oriented and adopts probabilistic approach.
Which of these statements is/are correct?

Question 7

It is estimated that an activity can be assigned an optimistic duration of 16 days, a pessimistic duration of 28 days and a most likely duration of 19 days. What is the expected duration for this activity?

Question 8

In the network shown below, the number of the arrow gives the duration of the activity. The earliest expected time for event 6 to be attained is

Question 9

PERT calculations yield a project length of 60 weeks with a variance of 9 weeks. Probability factor corresponding to 95% probability is 1.647; then the number of weeks required to complete the project with a probability of 95% is

Question 10

What is the proportional variation and what is the ‘range’ of project duration for the network as shown with the indicated probabilistic a, m, b durations of the respective activities?
