Use the networks in Figure 13.20 to determine ES, LS, EF, and LF for all activities (number in activity box is duration in days). Apply the buffer concept to the critical path. For Network

(a), use a 3-week time buffer for the critical path and a 1-week time buffer for every path that feeds into the critical path. For Network (b), use a 4-week time buffer on the critical path and a 2-week buffer for every path that feed into the critical path.
