- Ed is planning to build a treehouse as a present for his son's upcoming 10th birthday. The details for each task are as follows: DE F G AD C,E F 12 Task A B Preceding Task Duration (day) | 12 A B 10 12 5 Cost (RM) 50 140 120 60 70 80 60 (a) Obtain the following: • The number of days it will take for Ed to finish building the treehouse. • Which tasks are cannot be delayed at all without delaying the whole project. • The total cost of building the treehouse. (b) Due to illness, Ed has to begin building the treehouse later than planned. He reckons that he must reduce the build duration by 3 days to complete the treehouse by his son's birthday. He has determined the crash cost and crash time for each task as follows: Task А В С DE F G Crash Time (day) | 12 8 9 8 10 5 6 Crash Cost (RM) | 50 170 180 70 95 80 60 Obtain the following: • All tasks that are crashed and by how much. • The new total cost for building the treehouse.To complete the rotor assembly for an experimental spacecraft, Gilbert has laid out nine major activities involved.
