The managing partner of the Scott Corey accounting firm has decided that the system must be up and running in 16 weeks. Consequently, information about crashing the project was put together and is shown in the following table:

Activity Normal time Crash time Normal Cost Crash Cost Crash cost/pd Crash by Crashing cost

A 3 2 8000 9800 1800 1 1800
B 4 3 9000 10000 1000 0 0
C 6 4 12000 15000 1500 2 3000

G 4 2 8000 9400 700 2 1400
H 5 3 5000 6600 800 2 1600
TOTALS 69500 13500

(a) If the project is to be finished in 16 weeks, which activity or activities should be crashed to do this at the least additional cost? What is the total cost of this?

(b) List all the paths in this network. After the crashing in part (a) has been done, what is the time required for each path? If the project completion time must be reduced another week so that the total time is 15 weeks, which activity or activities should be crashed? Solve this byinspection.
