Assignment:
For the network shown:
a. List ES, EF, LS, LF, and Slack for all activities on the network and identify the critical path and completion time.
b. For the indirect cost, if the project can be finished in 26 days, it is $4500; if the project can be finished in 25 days, it is $4200; if the project can be finished in 24 days, it is $3900; if the project can be finished in 23 days, it is $3600; if the project can be finished in 22 days, it is $3200; if the project can be finished in 21 days, it is $2700.
For the time and direct cost data shown below, reduce the project completion time by three weeks. Assume a linear cost per week shortened, and show, STEP by STEP, how you arrived at your schedule. What is the new total cost after crashing the project by three weeks? What is the new critical path after crashing the project?
