Network diagrams (CPM/PERT): basic construction guidelines Consider standard rules for drawing activity-on-arrow networks. Identify the set of correct guidelines.

Difficulty: Easy

Each activity is represented by one and only one arrow in the network
Dangling (unconnected ends) must be avoided in the network diagram
A dummy activity consumes no time and no resources
All of the above

Correct Answer: All of the above

Explanation:

Guidelines explained
• One arrow per activity avoids duplication and ambiguity.• Avoid dangling ends; every activity must start/end at well-defined events.• Dummy activities exist only to maintain logic; they have zero duration and no resource use.

Final Answer
All of the above.
