Abstract: To reduce the energy consumption in the manufacturing process by optimizing job-shop scheduling, the process of the machines' energy consumption was divided into different stages. The energy consumption of each stage was analyzed and modeled. The job-shop scheduling problem model for manufacturing energy consumption was developed. On the basis of the developed problem model, minimizing manufacturing energy consumption was used as the optimization goal and a simulated annealing algorithm was adopted to optimize the job-shop scheduling. A job scheduling scheme was generated randomly according to the coding rule. The job scheduling scheme generated randomly was used as the initial solution, a simulated annealing algorithm was adopted to achieve the optimization of manufacturing energy consumption and the optimal job-shop scheduling scheme was obtained. The feasibility and effectiveness of the proposed method was verified by simulation experiments.

Key words: job-shop scheduling, manufacturing energy consumption, sustainable manufacturing, simulated annealing
