There are four critical paths in a network. A-B-C-D-E, A-F-E, A-B-H-J-K-Eand A-S-T-E. Each activity in this network can be crashed by a maximum of5 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 weekper activity). The crashing cost, second week and onwards(crashing secondtime), for activity A is $1200 per week, E is $1440 per week and for all otheractivities is $240 per activity per week. You have a maximum crashingbudget of $3005. The maximum possible reduction in the project duration willbe:a.3 weeksC b. 5 weeksC c. 4 weeksC d. 6 weeksC e.2 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 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
Consider a project that has been modeled as in the table below. Part a) Draw the PERT/CPM network for this project and determine the project’s expected completion time μP and its critical path. Part b) Suppose the standard deviations of the activity durations are σA = 2, σB = 1, σC = 0, σD = 2, σE = 3, and σF = 0. Then please estimate the standard deviation of the overall project’s standard deviation σP . Part c) Suppose for the standard Normal random variable Z, we know P[−1 ≤ Z ≤ +1] ' 68%, P[−2 ≤ Z ≤ +2] ' 95%, and P[−3 ≤ Z ≤ +3] ' 99.7%. Then, approximately what time T is one for which there is only a less than 2.5% chance for the completion time to beat (be shorter than)? *Please answer a-c and type your work and answers or write them neatly please* Thank you
