초록
This research introduces Overall Equipment & Energy Efficiency(OE2E), integrating production efficiency with energy management for sustainable manufacturing. Traditional Factory Energy Management Systems (FEMS) only monitor energy consumption, while Overall Equipment Effectiveness (OEE) measures production efficiency independently. OE2E combines both by multiplying OEE (availability, performance, quality rates) with Energy Efficiency (used/input energy ratio). The methodology creates three management zones: "Sustained Maintenance" (64-81 %), "Improvement Management" (36-56 %), and "Improvement Required" (25-30 %). An ESG scoring system uses current-to-previous period OE2E ratios for A-D sustainability ratings. Validation at an electronics facility confirmed OE2E's effectiveness in identifying improvement opportunities across production lines through comparative visualization tools. Key contributions include: expanding OEE to encompass energy efficiency, integrating FEMS with ESG management, providing quantitative metrics for simultaneous energy and ESG improvement, offering practical decision-support tools, and creating cost-effective ESG frameworks for SMEs. Future research will explore diverse manufacturing sectors, develop AI prediction models, enhance real-time data collection, and analyze OE2E-ESG performance correlations with financial outcomes. OE2E enables manufacturers to balance productivity with energy conservation, supporting climate objectives and ESG goals while maintaining competitiveness in environmentally conscious markets.
