Taking the regional integrated energy system as the research object; the study firstly conducts an optimization strategy analysis. Then; a multi-objective optimization is carried out; specifically targeting energy efficiency; economy; and environment. Subsequently; using an improved BWM method（HWBM）combined with the entropy weight method; an objective-subjective weight evaluation system is established; leading to the determination of an optimal system configuration and operational planning. Findings reveal that the design strategy effectively addresses the multi-energy coordination issue. Compared to the traditional combined cooling; heating; and power system; the optimal system achieves a 14.9% reduction in fossil fuel consumption; 8.9% in annual investment costs; 4.7% in energy costs per degree; 14.9% in carbon emissions; and 18.1% in water consumption. The outcomes emphasize the notable advantages in energy; and environmental protection. © 2024 Science Press. All rights reserved;
