Using critical path method, identify the critical activities and prepare a report determining the earliest and latest activity times, activity slack, critical path, duration for the project and crash the project.

Given the following project network, with the time estimated in weeks, answer the following questions:

Activity	A	B	C	D	E	F	G
Time	4	7	2	5	6	5	4

The crashing data of the project is as given below:

Activity	Time in weeks		Cost in SAR
	Normal	Crash	Normal	Crash
A	4	2	5000	7500
B	7	4	4500	6575
C	2	1	3000	3500
D	5	2	2750	3250
E	6	3	4250	5250
F	5	4	3750	4200
G	4	2	2575	3500

1. What are the critical path activities? What is the expected time to complete the project? (5 marks)
2. What is the total project cost using the normal times? (1 marks)

c.Crash the project to 18 weeks. What is the cost after crashing

A E Start Finish B D F G
