日本のGX文脈において
鉄鋼業は日本の産業部門CO2排出の主要源であり、焼結工程の炭素効率予測はScope1削減・省エネ投資判断に直結する。SSBJ・有報での気候関連開示が進む中、製造プロセスの炭素効率をリアルタイムに把握する技術は、排出量算定の精度向上やGX投資の根拠データとして日本企業に有用。
In the global GX context
Iron and steel is a hard-to-abate sector central to global decarbonization and transition finance. Predictive carbon-efficiency modeling at the process level supports Scope 1 accounting accuracy and operational decarbonization, complementing disclosure frameworks like ISSB/CSRD that increasingly demand granular emissions data. It adds an AI-driven process-optimization angle to the industrial transition literature.

📄 Abstract(原文)
Accurately predicting carbon efficiency is crucial for optimizing sintering operations in iron and steel production. This process is highly energy-intensive and has significant environmental and economic implications. However, the sintering process exhibits complex characteristics, including strong nonlinearity, time-varying dynamics, and operational uncertainties. These characteristics severely limit the performance of conventional modeling approaches. Existing data-driven methods often fail to capture temporal dependencies and handle uncertainty simultaneously, resulting in inaccurate and unreliable predictions. To address these challenges, this article introduces a novel type-2 fuzzy broad echo state learning system (T2FBESLS). This system integrates an interval type-2 fuzzy neural network into the feature layer of a broad learning system to improve uncertainty modeling. The enhancement nodes are replaced with echo state reservoirs that effectively encode the temporal dynamics of the sintering process. When evaluated using real-world industrial sintering data, the T2FBESLS achieved a reduction in root-mean-square error of at least about 15% compared to several state-of-the-art models. This demonstrates its superior prediction accuracy and stability. The key innovation lies in the fusion of type-2 fuzzy logic for handling uncertainty, broad learning for efficient structure expansion, and an echo state network for temporal modeling, offering a new approach to intelligent modeling in complex metallurgical processes.
