Proceedings of 2025 2nd International Conference on Machine Learning and Intelligent Computing, PMLR 278:573-586, 2025.
Abstract
The modern manufacturing is facing the challenge of energy saving and emission reduction. This study addresses the Multi-objective Green Flexible Job-shop Scheduling Problem (MGFJSP) with three objectives makespan, machine workload and carbon emissions, a Fuzzy Relative Entropy (FRE)-based improved Sparrow Search Algorithm (FISSA) is proposed. FISSA begins with special initialize methods to ensure a uniform distribution in solution space. Next, a logarithmic spiral is introduced in scroungers to enhance global search capability. Additionally, an insertion strategy is implemented to reduce machine idle time and carbon emissions. Finally, a FRE coefficient is introduced, where solutions are evaluated by comparing them with the ideal point, diversity is quantified, and selection is guided. Experimental results confirm that FISSA outperforms other multi-objective algorithms, significantly minimizing processing time and carbon emissions, demonstrate superior robustness and convergence.
