Method of hierarchical network plan for complex aviation product

Traditional project approach planning of aviation product is to manually build monolayer PERT network plan which has some difficulties, such as half-baked information, difficult to be modified, difficult to insert document flow and so on. Thus the project management of modern aviation product cannot be satisfied. A model of hierarchical network plan for complex aviation product was presented. Document flow and control flow were separated in the model and document flow could be easily inserted and modified in the model. A method to build hierarchical network plan was presented and the compatibility between document flow and control flow was analyzed. Time parameter of hierarchical network plan was also computed. The approach has been applied successfully in an aircraft wing project to verify its effectiveness.
