Fig. 8: HRC flexible manufacturing scheduling evolution framework.

The evolutionary framework consists of two phases: the self-evolution phase and the online application phase. The self-evolution phase is divided into two parts: the flexible job shop environment and the SFT LLM. In this phase, HDRs are evolved for 20 cases using the SeEvo framework. In the online application phase, the best HDR is derived through one run of the SeEvo, which is then applied to the HRC flexible manufacturing scheduling system to improve production efficiency.
