Description

Technical field: [0001] The invention belongs to the technical field of advanced manufacturing and automation, and in particular relates to an order-driven discrete manufacturing process energy consumption optimization method. Background technique: [0002] With the development of the manufacturing industry, order-driven customized production has become the mainstream. A single manufacturing enterprise often faces multiple order requirements from different customers. Therefore, the production method is a discrete manufacturing mode for multiple varieties and small batches, and its processing process is a complex process composed of different component processing sub-processes or parallel or series. On the other hand, my country is now the world's largest manufacturing country, and its manufacturing output accounts for about 20% of the world's total output. However, the development of my country's manufacturing industry is at the cost of high energy consumption. The energy c...
