Modeling and simulating for the manufacturing process of metallurgy based on System Dynamics

This paper describes the system structure about the manufacturing process of metallurgy, establishes the system´s System Dynamics (SD) model according to system´s circulation feedback relations. Based on the modeling, the system simulation on the different production pattern was carried on, and the change situation of the entire material flow and energy flow was demonstrated. The relation of the entire material flow and energy flow under the different production pattern was discussed, and the results expose the cause on the change of energy flow. Some beneficial advices for the decision-makers were given.
