Three activities are candidates for crashing on a project network for a large computer installation (all of course are critical). Activity details are in the following table:
Normal Normal Crash Crash
Activity Predecessor Time Cost Time Cost
A --- 7 days $6,000 6 days $6,600
B A 4 days 1,200 2 days 3,000
C B 11 days 4,000 9 days 6,000
A) What action would you take to reduce the critical path by 1 day?
B) Assuming no other paths become critical, what action would you take to reduce the critical path 1 additional day? (
C) What is the total cost of the 2 day reduction?
