CHAPTER EXERCISES 1. The following table contains task durations for a project. Time (Days) Task ID Minimum (a) Most Likely (m) Maximum (b) Immediate Predecessors A 10 22 38 B 3 7 12 11 25 44 B 42 D E 11 4 24 9 17 B B,C DE F F 2 5 9 4 8 H 11 24 G a. Construct an AON network diagram and identify the critical path. What is the duration of the critical path? b. What is the probability that the project gets completed by 85% of the critical path duration? 2. The following table contains expected duration times and expected cost for the set of tasks corresponding to a major design project that Dr. Christian Daniel is managing Task ID Expected Duration (Months) Expected Cost (5) Task Predecessor 1 1 2 2 1 3 1 2 2 3 4 1,500 3,000 1,500 3,000 1,500 3,000 1,500 3,000 4 2 5 6 1 2 8 7
