In reference to the attached image and data below: What are the final recommendations?

Step A we know: Critical Path = A, B, H, I, J; Project Time = 40 Weeks; Total Cost = 364,000

Step B we know: To crash the critical path I would crash A by 1 week, B by 2 week, H by 2 week and C by 3 week. This would not alter the critical path, only the time line.

Steps C we know: Modeling uncertainty in activity times. In this case I would use the activity times and determine the Variances and the Standard Deviation. Using “best case” (x) and “worst case” (y) scenarios for activity times the formula’s would be (x-y)/6 and (x-y)^2/36.
