基于Petri网的机床制造过程碳排放建模与量化方法

Modeling and quantification methods for carbon emission in machine tools manufacturing processes based on Petri nets

为减少机床制造业在制造过程中的碳排放,对机床制造过程的碳排放边界进行界定,并对机床制造过程碳排放特性进行分析;基于Petri网建立了机床制造过程碳排放模型,并提出机床制造过程碳排放动态量化方法。将上述理论研究应用到某企业的机床制造过程中,得到其机床制造过程碳排放量情况,并据此提出了节能减排的措施建议。

As the big typical consumer of energy resources, the machine tool manufacturing industry＇s carbon emission had significance on realization of our country＇s energy-conservation and emission-reduction. The boundary of carbon emission in machine tool manufacturing process was defined, and the characteristics of carbon emission were also analyzed. A carbon emission model for machine tool manufacturing process was constructed based on Petri net, and the dynamic quantification methods for carbon emission in the manufacturing process were proposed. The proposed methods were applied in a machine tool manufacturing factory, and its carbon emission condition was obtained. Thus the suggestions for energy-conservation and emission-reduction were given.
