An 11-activity PERT network with activity mean and variance as shown below in Figure 1. Assume all activities are stochastically independent and Z0.95 = 1.645.

c. Instead of PERT, you want to start the project under the Critical Chain Project Management methodology. Using the information given in Figure 1, how will you structure the critical chains. Show the critical chain, the project buffer, and the feeding buffers in terms of their placements. What is the size of the project buffer?
