Problem 2: (20 points total) The following table provides the information necessary to construct a project network and project crash data: Activity Predecessor Normal Costs Crash Costs 1 2. 3 4 5 6 - Normal Times (Days) 7 10 6 5 4 3 Crash Times (Days) 5 7 3 1 4 2 $100 $250 $400 $200 $150 $300 $400 $450 $805 $400 1 1 2, 3 4,5 $500 Knowing that the indirect project cost is $250 per day, crash the network the maximum amount possible and indicate: (a) (3 points) The Normal project completion time (b)(3 points) The Normal cost (c) (6 points) The Crashing Methodology (d)(3 points) Minimum project completion time (e) (3 points) The Crashing Cost (f) (2 point) The Total savings after Crashing
