Automatic layout of information in the AOE network

This paper mainly described a new method of automatic layout of information in the AOE(Activity On Edge) network with fixed-length arrows (time-independent), which could probably be applied in visualizing project management. With this method many complication problems of the manual typesetting of information could be well solved. To make a simply view of such method, this paper introduces the concepts of 4-tuple of the location of the information typesetting and the types of information, brings forward the realizing methods localization of the messages on the arrows and the method to display such messages in italic font, and finally use an example to validate its feasibility.
