Problem 1: (20 pts) 1- Construct the original network and calculate the activity dates and floats. 2- Then calculate the updated network and answer the questions that follow. Show your calculations Activity Duration Activity Duration Successor & Relationship M (FSO) N (FF4) A 7 H 5 K B C E wo 12 8 3 Successor & Relationship B (FSO) C (SS2) E (FSO) K (FS3) F (FSO) F (FSO) G (FS5) K (FSO) H (FSO) H (FSO) L (SF10) YJE 4 3 2 M (FSO) N (FSO) P (FSO) M F 6 N 5 P (FSO) G 5 P 6 . . Update information Data Date - Day 12 (end of day) Activity A began on day 0, and finished on day 9. Activity B started when A was complete (end of day 9), and has one day remaining duration. Activity C began on (end of day] 2 and finished on (end of day] 8. Activity E started end of day 9, and has 8 days remaining duration. Activity K duration has changed to 7 days due to production delays. The SF 10 relationship between G and L was incorrect. The correct relationship is FS 5. A new activity J, is added between K and M. It is a successor to K with FSO and predecessor of M with FSO. Its duration is 3 days. No other activities have started On the original network (Hint: On the baseline, LS of B = 9] What is the original duration? What are the original critical activities? Which activity has the greatest Free Float? How many days is it? On the updated network (Hint: ES of N = 38] What is the duration? What are the critical activities? Which activity has Free Float 1? What is the Free Float and Total Float of K? Which activity has the greatest Total Float? How many days is it? What is the Early Start and Early Finish of H? What is the Late Start and Late Finish of J? 2 Problem 1: (20 pts) 1- Construct the original network and calculate the activity dates and floats. 2- Then calculate the updated network and answer the questions that follow.
