Question 5

Activity X has the start to finish relationship shown with activity Y and both have early start and finish times as shown. Which statement is best?

Accepted Answer

A)   a 
B)   a 
C)   b 
D)   d < a

Question 6

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.
