  • The most common methods to visually construct such task network are AOA and AON diagrams, where the advantage of the first is the intuitive association of the graph lines to the activities, but the second is used much more often as it is easier to draw using computer software and it is more flexible when the specific parameters of the network ...
  • Project network logic errors include which of the following? A. Activities with less than 1 day duration B. Sequences such as "if test successful build prototype, if failure redesign" C. A sequence such as B succeeds A, C succeeds B, A succeeds C D. Both B and C are network logic errors E. A, B, and C are all network logic errors
  • AON project networks are easier to understand than AOA project networks for inex-perienced users, including many managers. 3. AON project networks are easier to revise than AOA project networks when there are changes in the project. For these reasons, AON project networks have become increasingly popular with practi-tioners.

  • The AON is the most widely used in all software packages; The AOA diagram can implement only F-S dependency; Hammock – Hammock is used in AON diagrams, to represent those activities which cuts across the phases of the project. Example :- Project management activities span throughout the life cycle of the project.

They include both the AOA (Activity on Arrow) and, most commonly used, AON (Activity on Node) formats of a network diagram. Activity network diagrams are used with project scheduling methodologies such as program evaluation and review technique (PERT), critical path method (CPM), and precedence diagramming method (PDM).

  • on two closely related network diagramming conventions, called activity-on-node (AON) and activity-on-arc (AOA). Most textbook authors favored the AOA convention, whereas most programs were written using the AON convention. Since the diagramming logic is much simpler for AON in comparison with AOA, the AON

  • A Network Diagram is a graphical way to view tasks, dependencies, and the critical path of your project. Boxes (or nodes) represent tasks, and dependencies show up as lines that connect those boxes. After you’ve switched views, you can add a legend, customize how your boxes appear, and print your Network Diagram.

  • Activity on Arrow (AOA) - We may need to add dummy activities to preserve logical relations Activity on Node (AON) Benefits of AON - Does not need dummy activities. - The sequence step calculation also made the AON to look more organized and clearer to read. - The technique is also well suited to computer implementation. defined. In an activity on node AoN) dag or (MPM (network), each activity corresponds one-to-one with a node, and we say that u v is represented if there is a directed path of arcs leading from v's node to u's node. Thus, an AoN dag is unique except for possible transitive arcs. In an activity on arc (AoA) dag or (PERT network),
