Question

Activity A B C D E F G H Time 5 3 7 6 7 3 10 8 a. Identify the critical path. b. How much time will be needed to complete this project

Answer 1

Answer:

Critical path = A-D-F-H

Duration = 22

Explanation:

Given:

Activity A B C D E F G H

Time 5 3 7 6 7 3 10 8

The objective is to identify the critical path and to find the time needed to complete this project

Solution:

The possible paths are as follows,

A-C-H = 5+7+8 =20

A-D-F-H = 5+6+3+8 =22

A-D-G = 5+6+10 = 21

B-E-G = 3+7+10 = 20

B-E-F-H = 3+7+3+8 = 21

a)

Critical is the path with the longest duration

Critical path =A-D-F-H

The duration is 22

b)

The duration to complete the project is as follows,

Duration = Length of critical path = 22
