Chapter 3, Problem 7P
Summary Introduction
To develop: An activity on arrow (AOA) network diagram, given a sequence of project activities between various nodes and to determine its minimum duration.
Introduction: In the activity on arrow (AOA) project network diagram, the arrow represents an activity which has a starting point and an ending point. The starting and ending points are nodes in an activity network diagram. The activity consumes time and other resources, which are shown by the arrow between two nodes.
