Question

Given the network plan that follows, compute the early, late, and slack times. What is the project duration? Using any approach you wish (e.g., trial and error), develop a loading chart for resources, Electrical Engineers (EE), and re-source, Mechanical Engineers (ME). Assume only one of each resource exists. Given your resource schedule, comp

ute the early, late, and slack times for your project. Which activities are now critical? What is the project duration now? Could something like this happen in real projects?

Note : In above diagram , the image is blurred. Calculations are completed from this diagram only.

Solution

In above diagram .,

Critical path is 1---4---5

Duration = 13

In following table Earliest , Latest , Slack have been calculated.

Resource schedule for Electrical Engineers (EE), and re-source, Mechanical Engineers (ME)

Activity Duration EST EFT LST LFT Slack = LST - Est 1 2 0 2 0 2 0 2 4 0 4 7 11 7 3 3 0 3 6 9 6 4 5 2 7 2 7 0 5 6 7 13 7 13 0 6 2 4 6 11 13 7 7 4 3 7 9 13 6
