i.
Draw the network diagram linking all the activities in a way that it shows if there exist any
preceding activity/activities before starting each of the mentioned activities in the above
table,
ii.
Showing the earliest start time, the earliest finish time, the latest start time and the latest
finish time of each of the activities in the project determine the completion time of the
project and the critical path.
ii.
Find the slack time (delay time) of each of the activities, the critical and the non-critical
activities.
Find the minimum possible completion time of the project by considering the crashed
completion times and the minimal total cost of that crashing the project.
iv.
Need proper handwritten answers. Thank you!
