Problem 3 (Project Crashing) For the following project, determine the schedule that gives the lowest possible total cost. The indirect cost is $90 per day. 0 \\ (9 6 \\/ Activity Normal Time Crash Time Cost to Crash (days) (days) per day A 7 4 $30, $50, $70 B 12 10 $60, $60 C 9 6 $40, $45, $65 D 3 3 N/A E 11 9 $35, $60 Note 1: Notice (in the above table) that, the cost to crash a task per day is not necessarily the same every day. For example: If you must crash A from 7 days to 6 days, it will cost you $30. However, if you must crash A from 7 days to 5 days, it will cost you $30 + $50 = $80. Note 2: Since Normal (Direct) Cost is incurred for each task whether you crash it or not, you do not really need the Normal (Direct) Cost of each task to determine the schedule that gives the lowest possible total cost. In other words, there is no \"missing data\" in this problem. However, if it helps, consider Total Normal (Direct) Cost as $C (a constant)
