Consider the project network pictured. Assume that the timesattached to each node are the means and the variances of the project completion times, respectively.a. Identify all paths from nodes 1 to 6.b. Which path is critical based on the expected completion times?c. Determine the probability that the project is completed within 20 weeksassuming that the path identified in part (b) is critical.d. Using independence of paths A–C–E and B–F–G only, recompute the answer to part (c).e. Recompute the answer to part (c) assuming independence of the paths identified in part (a).f. Which answer, (c), (d), or (e), is probably the most accurate?
What is the answer in the shortest path and shortest duration?
There are four critical paths in a network. A-B-C-D-E, A-F-E, A-B-H-J-K-E and A-S-T-E. Each activity in this network can be crashed by a maximum of 4 weeks. The crashing cost (per week), for the first week, for activity A is: $560, E is $565 and all other activities is : $140 (per week per activity). The crashing cost, second week and onwards, for activity A is $1120 per week, E is $1400 per week and for all other activities is $420 per activity per week. You have a maximum crashing budget of $2385. The maximum possible reduction in the project duration will be:
a.
5 weeks
b.
3 weeks
c.
4 weeks
d.
2 weeks
e.
1 week

- There are four critical paths in a network. A-B-C-D-E, A-F-E, A-B-H-J-K-E and A-S-T-E. Each activity in this network can be crashed by a maximum of 6 weeks. The crashing cost (per week), for the first week (crashing first time), for activity A is: $480, E is $495 and all other activities is : $120 (per week per activity). The crashing cost, second week and onwards(crashing second time), for activity A is $1200 per week, E is $1440 per week and for all other activities is $240 per activity per week.
