Find the critical path and critical time for the
following business network:
Activity Pre. Act. Duration
A - 18
B A 25
C B 1
D C 14
E C 12
F E 1
G D 18
H E,G 3
I C 14
J F,I 16
K J 5
L J 25
M H 22
N K,L 13
Dummy activity= an activity which is used to show logic dependance or relationship between of one activity over the other activity but does not consume any time or resources. It is represented by dotted....... Lines in network diagram.
Critical path= it is the maximum time consuming path from 1st event to last event in network diagram.
Time taken along the critical path is critical time or expected completion of project.
Answer - critical path A-B-C-I-J-L-N
critical time = 112
