In reference to the attached image: Determine the best way to crash the project to complete it in 35 weeks with revised activity slack times, critical path(s), and total project costs. Provide reasoning as to how all crashing decisions were made.
K Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined.

QUESTION 7 The Stone River Textile Mill was inspected by OSHA and found to be in violation of a number of safety regulations. The OSHA inspectors ordered the mill to alter some existing machinery to make it safer (add safety guards, etc.); purchase some new machinery to replace older, dangerous machinery; and relocate some machinery to make safer passages and unobstructed entrances and exits. OSHA gave the mill only 35 weeks to make the changes; if the changes were not made by then, the mill would be fined $300,000. The mill determined the activities in a CPM/PERT network that would have to be completed and then estimated the indicated activity times, as shown in the following Table 6: Table 6 Activity Description A B с D E F G H I J K Activity Description Order new machinery Plan new physical layout Determine safety changes in existing machinery Receive equipment Hire new employees Make plant alterations Make changes in existing machinery Train new employees Install new machinery…
