Aiming at the problems that setting up a quantitative model of concurrent procedure is so difficult that it is inconvenient to use computers to manage and control concurrent procedures, the author carefully analyzes the complexity and characters which general procedures including concurrent procedures have,studies and presents a kind of method of parametric modeling of fitting concurrent procedures management through constructing a sort of new network.The results of the research may be used in the research fields of concurrent design and concurrent engineering are expected to enable concurrent procedures to be managed,slmulated and controlled much more easily.
