PROJECT 1

Create a Precedence Diagramming Method (PDM) network diagram based on the following information to determine (a) the sequence of activities that make up the Critical Path, and (b) the total number of days for the project. There are 10 activities A through J.

Durations:

• Activities A, B, and H have durations of 5 days.
• Activities C, E, I, and J have durations of 2 days.
• Activities D, F, and G have durations of 4 days.

Predecessors:

• Activity C must precede Activity B.
• Activities A and F must precede Activity E.
• Activity E must precede Activity G.
• Activities B and D must precede Activities H and I, respectively.
• Activities G, H, and I may be conducted in parallel.
• Activities G, H, and I precede Activity J.

PROJECT 2

Create a Precedence Diagramming Method (PDM) network diagram based on the following information to determine (a) the sequence of activities that make up the Critical Path, and (b) the total number of days for the project. There are 10 activities K through T.

Durations:

• Activity K has a duration of 6 days.
• Activities L, P, and T have durations of 2 days.
• Activity M has a duration of 9 days.
• Activity N has a duration of 3 days.
• Activity O has a duration of 7 days.
• Activity Q has a duration of 2 days.
• Activity R has a duration of 7 days.
• Activity S has a duration of 1 day.

Predecessors:

• Activity K must precede Activity M.
• Activities L must precede Activities N and O.
• Activity N must precede Activities Q and S.
• Activity O must precede Activity P.
• Activities N and P must precede Activity Q.
• Activities M and Q must precede Activity R.
• Activities N and P must precede Activity S.
• Activities R and S must precede Activity T.

PROJECT 3

Given the Expected Duration (ED), calculate the Early-Start (ES), Early-Finish (EF), Late-Start (LS), Late-Finish (LF) times, and Total Slack (TS) for each activity as depicted in figure above. Determine (a) ES, LS, EF and LF for each activity; (b) slack for each activity; (c) the sequence of activities that make up the Critical Path; and (d) the total number of days for the project.

PROJECT 4

Given the Expected Duration (ED), calculate the Early-Start (ES), Early-Finish (EF), Late-Start (LS), Late-Finish (LF) times, and Total Slack (TS) for each activity as depicted in figure above. Determine (a) ES, LS, EF and LF for each activity; (b) slack for each activity; (c) the sequence of activities that make up the Critical Path; and (d) the total number of days for the project.
