use AOE net to estimate the time of project completion?Two principles:?? Only events that are represented by a vertex can start with activities from that vertex?? Only events that enter a vertex end, and the event that the vertex represents can occur?Calculate critical pathsFirst, in the AOE network, the path from the beginning to the end with the maximum path length (the sum of the time that each activity on that path lasts) is the critical path.To
