Description
technical field [0001] The invention relates to the field of energy-saving scheduling of forging production, in particular to an energy-saving scheduling method of a distributed forging flow shop considering centralized heat treatment. Background technique [0002] In the context of sustainable development, energy consumption is always a key issue facing the manufacturing industry. Forging production is an important production method in the manufacturing industry. Due to the existence of heating and heat treatment processes, its energy consumption is huge. As an effective energy-saving method, energy-saving scheduling has become a research hotspot, and more and more scholars pay attention to it. With the development of advanced manufacturing and intelligent manufacturing, the ever-shortening production cycle and the individual customization needs of users, distributed production is gradually replacing traditional production methods. It can be seen that the research on ener...
