The Use of Project Network Approaches for Scheduling

PERT:  Program Evaluation and Review Techniques

CPM: Critical Path Method

Either one of these approaches can make use of any one of the following methods:

AON = Activity on Node. This means that all activities are assumed to occur within the node (schematic block)

AOA = Activity on Arc. This means that all activities are assumed to occur on the arrow connecting the nodes.

Note: The Activity on Node (AON) method is most often used where:

Activity = Node

Event = The start and finish times of an activity
