The activities necessary for the completion of this project are listed in the following table: Immediate Predecessor(s) Activity Normal Time Crash Time Normal (weeks) (weeks) Cost $2,200 $2,200 5750 $2,300 $900 $3.000 $1,600 Total Cost with Crashing $2,850 $3.000 5750 $2.580 $1,200 $4.500 52.200 D.E

Answer 1

Answer: d) 7 weeks, $1330

Initial duration of project = 16 weeks

After maximum possible crashing, Project duration = 9 weeks.

The maximum weeks by which the project can be reduced = 16 -9 =7 weeks

Crashing Cost:

Crashing Cost of Activity D by 4 weeks = $280

Crashing Cost of Activity G by 2 weeks = $300

Crashing cost of Activity A & E by 1 week = $650 + $100 =$750

Total Crashing Cost = 280 + 300 + 750 = $1330
