A CPM PERT project network has probabilistic activity times x as
A CPM/PERT project network has probabilistic activity times (x) as shown on each branch of the network; for example, activity 1–3 has a .40 probability that it will be completed in 6 weeks and a .60 probability it will be completed in 10 weeks:


Simulate the project network 10 times and determine the critical path each time. Compute the average critical path time and the frequency at which each path is critical. How does this simulation analysis of the critical path method compare with regular CPM/PERTanalysis?
