7- A simple CPM network has three activities, A, B, and C. A is an immediate predecessor of B and of C. B is an immediate predecessor of C. The activity durations are A=4, B=3, C=8.
Define the critical path (CPM)
Homework Answers
Network diagram refers to the sequence of how the activities will be performed and arrange the activities in sequence and how they are dependent on one another.
CPM refers to critical path method where shortest path is taken to plan the project. The steps in CPM schedule include: -
- Individual activities are specified.
- Sequence of those activities are determined.
- Drawing a network diagram.
- Completion time of each activity is estimated.
- Critical path is identified.
- CPM diagram is updated.

A simple CPM network has three activities, A, B, and C. A is an immediate predecessor of B and of C. B is an immediate predecessor of C. The activity durations are A=4, B=3, C=5. The network has no critical path. The critical path cannot be determined without knowing PERT expected activity times. The critical path is A-C, duration 10.5. The critical path is A-B-C, duration 9. The critical path is A-B-C, duration 12.
