Models can solve many problems in systems engineering, so a new automatic structural modeling technology based on process manufacturing system identifications is presented. Through carrying out identifications to system compo-sitions and unit relationships, model structure data is refined, and a system simulation model is automatically generated. The graph theory is adapted and regarded as a math expression format of the industrial system in the modeling. In addi-tion, the rule codes are implemented for system units in the research, the identification functions are defined according to system composition properties. The auto-modeling processes are achieved through iterative computation. Finally, the example is given to verify that the presented method is feasible, and can satisfy these requirements of the availability, efficiency and accuracy.
