Question 16

What is the minimum cost completion time for this project if the activities have normal and crash costs as indicated and there is a $1,000 fixed cost for each day on site plus a $500 penalty for each activity that is crashed? The crash costs represent the cost of a fully expedited activity.For example,reducing activity Y from 13 days to 12 days costs an extra $100 on top of the $500 expediting cost for a total cost of $2,600.Reducing Y from 13 days to 10 days costs an extra $300 on top of the $500 expediting cost,for a total activity cost of $2,800.
