Abstract

Against the backdrop of the “dual carbon” goals, low-carbon transformation in the manufacturing industry has become a critical issue. Addressing the problem of equipment idling and hidden carbon emissions caused by unbalanced tact times in CNC machining production lines, this paper takes the motor rotor shaft production line of Company A as the research object and proposes an optimization method integrating carbon emission modeling, an improved NSGA-II algorithm, and FlexSim simulation. Firstly, a time-segmented carbon emission calculation model based on equipment operating states is constructed to quantify carbon emissions under processing, idling, and standby states. Secondly, a multi-constraint optimization model aiming to minimize both production tact time and carbon emissions is established, and an improved NSGA-II algorithm based on process coding is used to solve for the Pareto optimal scheduling scheme. Finally, FlexSim simulation is employed for verification. The results show that after optimization, the production line balance rate increases by 14.4%, the proportion of idling time decreases by 50.3%, and the carbon emission per unit product drops by 14.7%, validating the effectiveness of the proposed method in enhancing efficiency and reducing carbon emissions.
