All the statements provided are true differences between Activity on Node (AON) and Activity on Arrow (AOA) networks. AOA networks indeed sometimes require dummy activities to represent dependencies correctly. In AOA, nodes (points) do not consume resources or time; they represent events or milestones, while in AON, nodes represent the activities themselves. Both AON and AOA are used in practice, but tools like Microsoft Project typically use the AON approach. Lastly, the fundamental structural difference is that in AON networks, nodes represent activities, whereas in AOA networks, arrows represent activities.
