Following activities have been reduced so far and by the time duration as written in parenthesis:
B(2), D(1), E(1), H(1)
Now there are three critical path in the project. These paths and their resp. duration written in parenthesis are:
A-C-F-I (12), B-D-G-I (12), B-E-H-I (12)
Activities that can be crashed now and their remaining crash times are: A (1), D (1), E (2), F (3), G (1)
We need to crash an activity on all three of these paths to reduce project duration further. The least cost to do so is by crashing activities: A, D, E
Cost of crashing these activites by 1 time unit = 10+20+50 = 80
Next we need to crash activities E, F, G. Cost = 50+200+30 = 280
Now critical path B-E-H-I is fully crashed. So project duration cannot be reduced further.
Now project duration is 10 time units. All three paths are still critical.
Total cost of project = normal cost (680) + crash cost (10+70*2+20*2+50*3+200*1+30*1+40*1)
= 1290
