Problem 03: A project consists of 10 activities, lettered A through J, below. For each activity, the preceding activity is given, and a deterministic estimate of the length of time required completing it in days. Activity Activity A B C D E Immediate Predecessor(s) A B B Duration (Days) 4 5 2 2 3 F G H I J Immediate Predecessor(s) E E C, D, E C, D, E G, H Duration (Days) 2 8 7 5 6 a) Find the critical path and project completion time. b) Can activity E be delayed without delaying the project completion time? If so, how many days? c) Can activity D be delayed without delaying the project completion time? If so, how many days? If $1000 can be saved for each delayed day of activity D, then how much dollar can be saved keeping the project completion time unchanged? d) Activity H needs a delayed time of one day and an extra time of one day. Is it possible by keeping the project completion time unchanged? Explain. e) The PM wants to shorten the duration of the activity J from 6 days to 4 days. What is the impact of this change on project completion time and critical path?
