Consider a small project consisting of the following activities: Activity a b c d e f Immediately preceding activity - - - a, b a, c a, b, c Duration (weeks) 6 12 13 5 4 16 (a) Draw the network diagrams (AOA and AON both) for this project and determine the critical path. What is the minimum completion time for the project? (b) If it is found that some extra resources may be available so that activity c may be crashed by a maximum of 2 weeks, what will be its impact on the critical path(s) and the project completion time? (c) If instead of single time estimates, we have the following three time estimates (to , tm , tp ) for each of the above activities from a through f in that order, then what will be probability that the project’s completion will be delayed beyond 30 weeks? (Time estimate) (2,5,14) (3,12,21) (5,14,17) (2,5,8) (1,4,7) (6,15,30)
