Networks: Critical Path Analysis
Use the project (activity) network. Forward scan for earliest start and finish times, backward scan for float, and identify the critical path and the minimum project time. The answer key highlights the critical activities.
- 1.In the project (activity) network shown, find the minimum time to complete the whole project.
Activity network: each arrow is an activity labelled with its name and duration. - 2.In the activity network shown, find the earliest start time (EST) of activity E.
Activity network: each arrow is an activity labelled with its name and duration. - 3.In the activity network shown, activity E takes 2 units. Find its earliest finish time (EFT).
Activity network: each arrow is an activity labelled with its name and duration. - 4.In the activity network shown, find the float (slack) time of activity B.
Activity network: each arrow is an activity labelled with its name and duration. - 5.In the activity network shown, list the activities that lie on the critical path (the activities with zero float).
Activity network: each arrow is an activity labelled with its name and duration. - 6.In the activity network shown, find the earliest event time of node 1 (the earliest time every activity leading into it can be finished).
Activity network: each arrow is an activity labelled with its name and duration.
