What is a Aon chart?
An AON (Activity-on-Node) chart displays a graphic illustration of a project as a network diagram, consisting of nodes representing projects or tasks, linked by vectors (directional lines) representing dependencies in the project.
What is difference between activity on node and activity on arrow?
In activity on arrow diagrams, arrows are used to show activities. In activity on arrow diagrams, nodes are called events. First node is always the “START” event and last node is the “END” event. On the other hand, in activity on node diagrams, activities are shown on the node.

Thus, while AON is a network diagramming tool, PERT is a time estimation tool. Both tools are used to together to find the critical path and estimate the maximum time required to complete the project in project scheduling.
What is activity on arrow AoA?
The activity on arrow (AoA) technique is a project management tool for mapping and scheduling activities, such as tasks or events. Project managers use circles, referred to as nodes, to represent each activity of a project. Each node has sections that denote the earliest and latest event start times.

What are the strengths and weaknesses of AOA and AON techniques?
What are the strengths and weaknesses of AOA and AON techniques? AON techniques are easier to learn and allows for ease of labeling and interpretation as long as the number of activities is not too large. AOA can be easier on the eyes if the project has a large number of activities.

What is the difference between AOA and AON?
The main difference between AOA & AON is AOA diagrams emphasize the milestones (events); AON networks emphasize the tasks. Activity on Arrow Advantages: An arrow denotes passage of time and therefore is better suited (than a node) to represent a task.
What is AOA in network planning?
Abstract: Both AON (Activity-On-Node) and AOA (Activity-On-Arrow) network diagrams are universally used network planning formats, but they have different characteristics and representations, which has caused inconvenience for engineering technicians to learn and use network planning technique.
