Part 1: AON (40 points) AON (Activity on Node) Network diagram using the most likely duration from the table below. The network should only use and show defined precedence relationships. Indicate the critical path and calculate the duration of the project. The AON diagram should show the task predecessors and the ES, EF, LS, LF, TS, FF times in a manner similar to the example from the lecture. Note, however, that you are requested to draw the diagram with Most Likely Durations, and thus you may omit the expected time and variance. Also note that network diagrams show durations, not calendar days. All Durations Are In Weeks.
