英文摘要:

      Material flow analysis is one of the important methods to study the circular economy. In this paper, the modeling method of material flow system with different complexity in the process of manufacturing enterprise was studied. First of all, this paper reviewed the domestic and foreign researches on the modeling theory of material flow field. The material flow analysis method based on material input output table, the theoretical level analysis of material flow based on graph theory and the material flow analysis method based on software were reviewed. And then analyzed its characteristics and modeling method. Finally, the application of Petri net modeling and simulation tools in the analysis of circulation material flow was discussed, and the applicability of different types of Petri nets in solving different types of material flow problems was studied, which might provide theoretical supports for material flow modeling and simulation.
