Whats an arrow diagram?

An arrow diagram is defined as a process diagramming tool used to determine optimal sequence of events, and their interconnectivity. It is used for scheduling and to determine the critical path through nodes.

What is the use of activity diagram?

An activity diagram shows business and software processes as a progression of actions. These actions can be carried out by people, software components or computers.

Is it mandatory to use activity on node (AON) for CPM problems and activity on arrow (AOA) for PERT problems? We know that CPM uses activity oriented network (since nodes represent activities) and PERT uses event oriented network (since nodes represent events).


What is activity and event in network diagram?

Term # 1.
