a) Draw a CPM network by using information on Table 3a. (pdf file) b) Compute ET(i), LT(i), TF(i,j), F(i,j) and find critical path using the network in Question 3a. (pdf file) c) Using the information on Table 3c, evaluate the problem under PERT perspective and find expected duration of activities on each path E(Tij), variance of duration of activities on any path varTij. After finding these, compute ET(i), LT(i), TF(i,j), F(i,j) and find critical path again.
