Research on autogeneration of Active-on-Arrow network chart in project management

The Active-on-Arrow Network Chart is the most popularity tool in Network Planning Technology, but it is difficult to draw in complex project. The best way is drawing the network chart automatically by software. An automatically drawing method of network chart is described in this paper. Firstly, the paper analyzes the characteristics of the Active-on-Arrow Network Chart and summarizes the steps to draw the network chart automatically, and secondly provides corresponding solutions on the expression of the logic relation, the automatic numbering of node, the adding of the dummy activity and the arrangement of the network chart. Lastly, the paper introduces the effect of the network chart autogeneration system. With the system, Active-on-Arrow network chart can be drawn clearly and completely.
