The answer is given before but I need specification. Please do the followings: answer a. Draw network for showing the dependencies and b. draw precedence network diagram . then please separately answer c, d, e even if the answer is on a and b . (don't provide aoa diagram)

Problem 2 [40 points) 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 (e.g., add safety guards); 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 PERT network that would have to be completed and then estimated the indicated activity times, as shown in the table below. Construct the PERT network for this project and determine the following Draw a network diagram showing the dependencies Draw a Precedence network diagram Do forward pass and backward pass calculation What are the slack for each of the paths Which one is the critical path for this case? b. c. d e Activities Immediate Predecessor A 2 B Description Order new machinery Plan new physical layout Determine Safety Changes in existing machinery S 3 10 D E F A A 10 7 15 B G 9 Receive equipment Hire new employees Make Plant Alterations Make changes in existing machinery Train new employees Install new machinery Relocate old machinery Conduct employee safety Orientation H DE D,E,F D,E,F,G 3 4 5 J K HIJ 2 HINT: Round the time estimatet (or te) to zero decimal point; it will simplify your calculations. Round the variances to two decimal points. Use the following legend to draw the Network Diagram.
