assume that there is new one-day lag Finish-to-Start between activities D and E (FS = 1 day). 

1. What is the normal duration and the cost of the project?  Round up all costs to zero decimals.
2. Which activities should you crash to meet a project deadline of 16 days? Consider that there Indirect costs are $1,500 (in normal duration of the project), and there is $100 in indirect cost savings per day saved. Draw a new AON each time you make a one-day reduction decision. Make sure you show the last AON network reaching EF = 16 days.
3. What is the cost of crashing the activities you selected (no decimals)?
4. What is the new TOTAL cost of the project -no decimals (i.e., crashing included to reach 16 days)?

 

Activity	Predecessor	Crash time (days)	Crashed cost	Normal time (days)	Normal cost
A	-	3	5,700	4	4,100
B	A	6	3,700	9	2,000
C	B	1	3,500	4	2,500
D	A	6	4,900	7	4,300
E	D	3	2,000	4	1,600
F	D	3	3,500	5	2,500

To determine the normal duration and cost of the project we need to calculate the Early Start ES Early Finish EF Late Start LS Late Finish LF and Total Float TF for each activity The projects duration ... View the full answer
