Problem #3-Time-Cost Trade-Off Analysis (20 Points) Given the precedence diagram below, perform the following: a. Perform forward and backward pass calculations to calculate Early Start (ES). Early Finish (EF), Late Start (LS), Late Finish (LF) and Total Float (TF) for all activities and identify the critical path. (5 points) b. Create a crashing list from the critical path activities found in Part A using the provided table. (5 points) c. Utilize the Least-Cost crashing solution to compress the schedule as much as possible. List the crashing steps on the provided table. How does this network compression affect the project schedule? How much total cost has been added to the project? Identify any new critical path(s) that are created due to the least-cost crashing process.
