A directed network for this project will require a dummy activity.
Sketch the network diagram, clearly identifying the dummy activity. (3 marks)
An engineering project requires activities A to G to be completed, as shown in the table.
The minimum completion time for the project is 25 days and the critical path includes activities B, D, E and F. The float for activity G is two days and the float for activity C is four days.
Find the possible duration for each of the activities A, C, F and G. Include a network diagram in your answer. (5 marks)
An engineering project requires activities A to G to be completed, as shown in the table.
The minimum completion time for the project is 40 weeks and the critical path includes activities A, C, E and G. The float for activity F is six weeks and the float for activity D is 9 weeks.
Find the possible duration for each of the activities B, D, F and G. Include a network diagram in your answer. (5 marks)

The network below shows the activities and their completion times (in hours) that are needed to complete a project.
The project is to be optimised by reducing the completion time of one activity only.
This will reduce the completion time of the project by a maximum of
A. 1 hour
B. 3 hours
C. 4 hours
D. 5 hours
