3. (30 marks) Consider the following activity on node project where numbers in parenthesis are activity durations. For instance, activity 5 has a duration of 4 time units. 1 (6) 544) 10(1) 2(2) 6(1) We wish to reduce the project duration to 19 periods with minimal additional cost. Below we are given the normal duration and crash duration costs as well as crash times. Activity Immediate Predecessor (list Normal Crash Namo numberame, separated by Time Time 6 2. 1 3 1 3 3 4 2 2 2 5 3 4 2 6 4 1 1 7 5,6 1 1 8 7 6 3 3 8 3 2 10 8 1 1 11 9.10 1 1 Normal Cost $100 $100 0 0 $100 0 0 $100 $100 Crash Cost $240 $150 0 0 $180 0 0 $160 $140 0 0 0 Tabulate the iterations in your solution below. If there are ALTERNATIVE solutions, wite them down as well.
