Step 1
It is the longest path through the project network, and any delay in any activity on this path will directly impact the project's completion time. The Critical Path is essential because it helps project managers identify the most critical tasks that require close Show more…

For the following project management, schedule the project for minimum cost between the crash and normal times. a. Calculate Critical Path and critical time for both normal time and crash time. (4) b. Calculate the probability of the project for (critical +1) days & (critical time-1) days. (3) c. Schedule the project for minimum cost. Write clearly each stage of iteration and draw the network at every step. (10)

What is the critical path and time duration? A simple CPM network has three activities: A, B, and C. A is an immediate predecessor of B and C. B is an immediate predecessor of C. The activity durations are A = 4, B = 3, C = 8. (A) The critical path is A-B-C, duration 15. (B) The critical path is A-C, duration 12. (C) The critical path is A-B-C, duration 13.5. (D) The critical path cannot be determined without knowing PERT expected activity times. (E) The network has no critical path.
1. Compute the expected time and variance for each activity. 2. Determine the critical path and the expected duration of the project. What is the probability that the project will take longer than 58 days to complete? Which path in the project network offers the greatest risk of overrunning a new deadline of 56 days?
