By analyzing the project’s work breakdown structure (WBS) and organization breakdown structure (OBS), the authors raised a way to design and arrange project network diagram by levels and grades, and further proposed the general principles and methods to simplify and complicate the network diagram. This paper embodied achievements of the authors’ research in hierarchial activityonarrow network and computer aided design.The authors also put forward the way to extract certain subnetwork, describing its surroundings in the general network diagram. A software (Hnetwork 1.0) of hierarchial network was developed based on these methods. The concept and applying methods of the grade network diagram purposed in this paper can not only reveal characters of both project’s WBS and OBS, but also satisfy the requirements of project management in levels and grades. It is of value to be promoted for wide applications.
