project management
A project contains the following activities and relations.
a) Construct the associated project network.
b) Find earliest and latest occurence time of each activity.
c) Find the critical path of the project.
d) Construct time schedule of the project.
e) Compute total floats and free floats for the noncritical activities of the network and
discuss their use in finalizing a schedule for the project (give at least one example).

Homework Answers
Answer [A] Project Network
Answer [C]
Critical Path = A-C-D-F-G-H-J-L-N-S-T
Project Duration = 38
Answer [B]
Free float = subtracting the early finish (EF) of the activity from the early start (ES) of the successor activity.
Total Float = Late finish - Early finish Or Early finish - early start
