Explanation / Answer
The parallel paths and their corresponding durations as follows :
A-E-F = 2 + 3 + 0 = 5 weeks
A-C-D-F = 2 + 1 + 4 + 0 = 7 weeks
B-C-D-F = 5 + 1 + 4 + 0 = 10 weeks
B-D-F = 5 + 4 + 0 = 9 weeks
Since , B-C-D-F has the longest duration , it forms the critical path .Since, project completion time is same as duration of critical path, project completion time is 10 weeks .
CRITICAL PATH = B-S-D-F
PRJECT COMPLETION TIME = 10 WEEKS
Slack of activity A
= Duration B-C-D-F – Duration A-C-D-F
= 10 – 7
= 3 weeks
Slack of activity E
= Duration B-C-D-F – Duration A-E-F
= 10 – 5
= 5 weeks
Therefore, activity E will have maximum slack of 5 weeks
ACTIVITY E WILL HAVE MOST SLACK OF 5 WEEKS
CRITICAL PATH = B-S-D-F
PRJECT COMPLETION TIME = 10 WEEKS
