Abstract
Blanks, an important raw material for the manufacturing industry, are semi-finished products for further processing. The energy consumption and processing efficiency in the process of blank production and use can be determined to a great extent in the blank design stage. The design of appropriate blank dimensions is an important means of realizing ecological civilization. Current blank designs seldom consider the production conditions of enterprises. In order to design energy-saving and efficient blanks on the basis of the actual conditions of an enterprise, this paper establishes the blank dimension optimization design model from the perspective of a business compass. With energy savings and efficiency as the goals, and the blank production and use-process equipment parameters as variables, the blank dimensions were optimized by an NSGA-II algorithm, and the results showed that the energy efficiency and processing efficiency of the designed blank dimensions were significantly better than for the existing blank dimensions in the process of enterprise operation.
Highlights
Nowadays, blank-dimension design is being given increasing expectations for achieving energy efficiency and emission reductions
Blank dimensions are the link between the production and use of blanks, and the energy consumption in the process of production and use of blanks accounts for more than 80% of the energy consumption in the manufacturing industry
It is worth mentioning that the blank design stage is very important, and can determine the energy consumption of more than 80% of the blank process [3,4]
Summary
Blank-dimension design is being given increasing expectations for achieving energy efficiency and emission reductions. Li et al established an optimization mathematical model using a simulated annealing algorithm (SAA) to minimize the energy consumption of a blank’s processing [24]. Various optimized methods have been promoted by many scholars to analyze blank dimension design and select the blank’s dimensions to reduce energy consumption and the time of blank production and processing. In the process of blank-dimension design, few studies take into ac of blank’s count the actual situation of the enterprises using the blank, and the design of the dimensions to meet energy-saving needs to the greatest extent is difficult. The blank dimensions that best met the actual production requirements of theInenterthiswere method, energy and consumption and time are set as optimization objectives, and the prise optimized calculated. Blank-Dimension Design and the Business Compass enterprise were optimized and calculated
