Running head: Unit Exercise 1 Page no.-1 Ans 1.) Activity on arrow network - In this network, the activities are represented by a line node or line in between two circles. These two circles represent the start and end of activities, respectively. The start of the activity is known as start event (I node) and the finish of the activity is known as finish event (j node). Activity on node network - In this network, to denote scheduled activities, boxes are used. These boxes are connected from start to end with arrows to represent a progression logic of the activities and their connection and dependency on each other. Differences - AOA has a limited potential as it shows only finish to start relationships whereas AON can accommodate any kind of task relationship like start to start, finish to finish, finish to start, start to finish. Scheduling on an AOA diagram is easier than AON diagram as AOA requires a smaller number of arrows than AON and hence the network is clearer and more understandable.
