Problem 5-14 (Static)
Here is a CPM network with activity times in weeks:
a. Determine the critical path.
a. A-E-F-D
b. A-E-G-C-D
c. A-B-C-D
b. How many weeks will the project take to
complete?
c. Suppose F could be shortened by two weeks and B
by one week. By how many weeks would this reduce the project
duration?
Answer: a. A-E-G-C-D
The given network paths are
A-E-F-D = 7+4+8+6 = 25 weeks
A-B-C-D = 7+5+6+6 = 24 weeks
A-E-G-C-D = 7+4+3+6+6 = 26 weeks
The critical path is A-E-G-C-D with the duration of 26 weeks
Answer b: The project takes 26 weeks to complete
This is based on the critical path of the project. The duration of critical path is 26 weeks
Answer c. 0 weeks
The activity B and F are not on the critical path and hence, it will not make any difference to the critical path.
