Answer all question. Please answer in the space provided, and show work wherever applicable. #1. There are three critical paths of a project, CP1, CP2 and CP3.The time length of each path is as follows (5 points): CP1 = 56 days; CP2 = 58 days, and CP3 = 70. You will circle one or more of the following. If you circle one response that is correct and one response that is incorrect, your answer will be counted as incorrect. A. It is quite possible, and the project time is the average of the three times. B. It is impossible to have three critical paths. C. It is impossible to have critical paths with different time lengths. #2. We have TWO critical paths, and the project completion time is 100 days; both the paths are distinct and have no common nodes. We have been asked by the client to crash the project by 20 days. One of the critical paths can be crashed at most by 15 days, and the other critical path can be crashed by at most 25. Cn we crash the project by 20 days as requested by the client? If yes, why? if not what is the maximum we can crash on the project. (5 points) #3 A node has an early start (ES) of 10 days; it takes 25 days to finish the job. After the application of CPM the node is found to be on the critical path. What is its Late Start time or LS Samples FINAL #4. Consider a node on project network that takes 15 days to complete. After the application of CPM the node was found NOT TO BE on the critical path and actually had a slack of 3 days; its early start time is 26 days. What are its EF(early finish) and LF (Late finish) times? (7.5)
