Please solve the following problems related to Chapter 17: Project Management: 1. Based on the following AOA diagram, please answer the following question: (1) Determine the critical path and the expected project duration (2) Determine the following quantities for each activity: the earliest start time, the latest start time, the earliest finish time and the latest finish time and the slack time. C (7) 4 F (5) I (6) A (4) B (10) D (11) 3 5 E (12) G (3) 6 7 H (10) 8 2. Here is an Activity on Arrow (AOA) network diagram for a project. The lettered A through F represents an activity, as shown in the accompanying precedence diagram. o O A O The probabilistic time for each activity is as follows Activity Time Activity A 4-5-6 D B 2-5-6 E C 3-4-5 F What is the expected time and standard deviation of each path? [1] E Time 4-5-6 2-5-6 3-5-8
