I have attached the question with the charts. Here is my answer: I know that I have A1, A1a, and A2 correct. What I need help on are these answers I have come up with: For A3a. I have the answer: Expected duration of the entire project ACEHJ = 27 weeks BDHJ = 33 weeks BFGIJ = 33.5 weeks For A3b. I have the answer: slack for project a = 33.527 = 6.5 weeks For A3c. I have the answer: slack for project task H = 33.533 = 0.5 weeks For A3d. I have the answer: the week project task F is scheduled to start 8th week. For A3e. I have the answer: the week project l is scheduled to finish 30th week. For A4. I have the answer: Determine the probability of completing this project in time for the product launch in 34 weeks. (DS)/Square root V = 3433.5/6.53^.5 = .5/2.5553 = 0.2 Probability = .0793 or 7.93% I know that I have B1, B2 and C1 correct What I need help on is: For C2. I have the answer: Both tasks should be crashed by the maximum possible: 4.5 weeks for Task D and 4 weeks for Task F for a total time saving of 8.5 weeks. For C3. I have the answer: Taken individually, crashing cost will come to $8,000 across all 4.5 weeks Task D will be compressed while the corresponding cost to save 4 weeks on Task F will come $4,000. I have been working on this problem for about 2 weeks now. It's tough, but it's the last problem before I finish this class. PLEASE HELP!!!!!
