Question 1

a) From the following logic table draw an AON network diagram to calculate the normal project duration of the project and identify the critical path:

Activity	Dependency	Normal Duration (weeks)	Normal Cost ($)	Crash Duration (weeks)	Crash Cost ($)
A	-	4	500	3	650
B	A	3	100	3	100
C	A	5	300	3	360
D	B	4	200	2	280
E	A,B	3	350	1	470
F	C	4	50	2	100
G	D,E,F	2	650	1	725

b)Draw a Gantt chart for activities A G.

c) Do crashing to reduce the project duration by 5 weeks. Show steps.
