Abstract

The improvement of energy efficiency is considered as one of the keys to the sustainable development of manufacturing enterprises. This paper proposes an energy efficiency improvement method for the manufacturing process. Based on the analysis of the characteristics of energy consumption in the manufacturing process, a necessary energy consumption model, an assistant energy consumption model and an ineffective energy consumption model are constructed for identifying the energy consumption attributes of the manufacturing process. Then, the relationship model of energy consumption is built, and the energy efficiency improvement method for the manufacturing process is proposed based on ECRSR (Elimination, Combination, Rearrangement, Simplification and Recovery). Finally, an injection molding machine in a workshop is studied as a case. The results show that the average hourly power-saving rate of a single machine is 37.3%, and the average power-saving rate per piece is 30.9%. This paper provides a feasible method for improving energy efficiency of the manufacturing process from the perspective of IE (Industrial Engineering), and provides both theoretical and methodological support for the sustainable development of the manufacturing industry.
