Repeat Exercise 4.20 and consider the lead-lag PDM restrictions. Draw the Gantt chart schedule that satisfies all the lead-lag constraints.

Exercise 4.20

Assume that we have the following precedence diagramming network data:

The following PDM restrictions are applicable to the network:

\[ \begin{aligned} & \mathrm{SS}_{\mathrm{AB}}=3 \\ & \mathrm{FF}_{\mathrm{AB}}=12 \\ & \mathrm{FS}_{\mathrm{BC}}=1 \\ & \mathrm{SS}_{\mathrm{BD}}=6 \\ & \mathrm{SF}_{\mathrm{DE}}=13 \\ & \mathrm{FS}_{\mathrm{FG}}=3 \end{aligned} \]
If the project start time is \(t=5\) and the project due date is \(t=52\), perform conventional CPM analysis of the network without considering the lead-lag PDM restrictions. Show both forward and backward passes. Identify the critical path. Tabulate the TS and FS for the activities in the network.
