Consider a project that has been modeled as shown in the following table. Activity A Immediate Predecessors Duration (hr) 7 B 9 C A 4 D A 31 E A 7 F B, C 11 G B, C 14 H E, F 10 I E, F 26 ] E, F 60 K D, H 22 L G, J 26 (a) Draw the PERT/CPM network for this project and determine the project's expected completion time (in hours). 30 hr Determine the project's critical path. (Enter your answers as a comma-separated list.) 25 (b) Can activities E and G be performed simultaneously without delaying the minimum project completion time? Yes No (c) Can one person perform A, G, and I without delaying the project? Yes No (d) By how much (in hours) can activity G be delayed without delaying the entire project? hr By how much (in hours) can activity L be delayed without delaying the entire project? hr (e) How much would the project be delayed if activity G was delayed by nine hours and activity L was delayed by six hours? Explain. The project would be delayed hours since G and Lare on the same path
