Please solve the following problem related to Chapter 17: Project Management 1) Here is an Activity on Arrow (AOA) network diagram for a project. The lettered A through F represents a sub-project, as shown in the accompanying precedence diagram. The deterministic time for each activity is as follows Activity Time Activity Time A 4 D 6 B 6 E 8 C 5 F 3 (a) Which path is the critical path? What is the expected duration of the project? (b) Please compute the Earliest Start (ES), Earliest Finish (EF), Latest Start (LS), Latest Finish (LF) and Slack time for each activity. 2) Here is an Activity on Arrow (AOA) network diagram for a project. The lettered A through F represents a sub-project, as shown in the accompanying precedence diagram. D G H The probabilistic time for each activity is as follows Activity Time Activity A 2-4-6 E B 3-4-5 F C 3-4-5 G D 3-5-7 H (1) What is the expected duration of path C-E-H? (2) What is the standard deviation of path C-E-H? Time 2-5-6 3-4-6 4-5-6 3-5-7
