Use a PERT network to establish the expected duration for the project described in the table below: (SHOW the PERT NETWORK)

Activity	Predecessors	Duration a m b			Exp. Duration	Var.	Crash Week 1	Crash Week 2
A	-	3	6	9			700	100
B	A	6	7	14			600	200
C	A	4	6	14			400		600
D	B, C	4	6	8			200		600
E	B, C	6	9	12			400	300
F	C	4	6	14			200	900
G	D, E	3	5	7			400	400
H	E	3	6	9			600	100
I	G	8	8	8			600
J	H	4	10	16			700	300

a. List the activities on the CRITICAL PATH:

b. What is the project expected duration?...........

c. In your table list ALL expected durations and ALL variances.

d. List is the slack for: J .. I F. C

e. List the latest starting time for: G .. F E .

f. The company indicated that they need to have a 90% probability of completing in 39 weeks.

What will become of the expected duration to make sure that we meet the 90% probability to

complete within 39 weeks?......................

g. Because of the new expected duration, (see f), how many weeks are to be crashed?.............

h. List specifically which activities you would crash, and for how many weeks:
