Solution

The time used in PERT (Program Evaluation Review Technique) for drawing the Network diagram is the Expected Time.

Here's why:

a. Optimistic time: This is the minimum possible time required to accomplish a task, assuming everything proceeds better than is normally expected.

b. Pessimistic time: This is the maximum possible time required to accomplish a task, assuming everything goes wrong (but excluding major catastrophes).

c. Most likely time: This is the best estimate of the time required to accomplish a task, assuming everything proceeds as normal.

d. Expected Time: This is the best estimate of the time required to accomplish a task, taking into account the risk or uncertainty in the time estimation. It is calculated as (Optimistic time + 4*Most likely time + Pessimistic time) / 6.
