Abstract: Activity-on-arrow network is a very important map in modern project management. Against the traditional method of drawing activity-on-arrow network, in the process of which exists a lot of crossover, the messy layout and complex structure, this paper proposes a method of drawing activity-on-arrow network by studying some key issues, such as calculating and arranging the position of the activities, suspending activity, producing dummy activity, optimizing network diagram and so on. The cases show that the method of generating activity-on-arrow network has the characteristics of high efficiency, few cross and simple structure.
