日本語
本研究は、低炭素電炉(EAF)製鋼における金属チャージ配合の再現可能な確率的多目的最適化フレームワークを提示する。コスト、炭素排出、循環性、金属歩留まり、残留元素制限、多サイクルリサイクル、CVaRリスク制御、モンテカルロシミュレーション、Sobol–Jansen感度分析を統合し、製品固有の確率的最適化がオフスペックリスクを大幅に低減しつつ、スクラップ利用、バージン鉄希釈、コスト、排出のバランスを取ることを示す。
English
This study presents a reproducible stochastic multi-objective framework for optimizing metallic charge blends in low-carbon EAF steelmaking. It integrates cost, carbon emissions, circularity, metallic yield, residual-element limits, multi-cycle recycling, CVaR-based risk control, Monte Carlo simulation, and Sobol–Jansen sensitivity analysis. Results show that product-specific stochastic optimization can substantially reduce off-specification risk while balancing scrap utilization, virgin-iron dilution, cost, and emissions. The framework supports comparative decision-making and can be adapted for plant-specific applications.

📄 Abstract(原文)
This study presents a reproducible stochastic multi-objective framework for optimizing metallic charge blends in low-carbon electric arc furnace (EAF) steelmaking. The model integrates cost, carbon emissions, circularity, metallic yield, residual-element limits, multi-cycle recycling, CVaR-based risk control, Monte Carlo simulation, and Sobol–Jansen sensitivity analysis. Results demonstrate that product-specific stochastic optimization can substantially reduce off-specification risk while balancing scrap utilization, virgin-iron dilution, cost, and emissions. The framework supports comparative decision-making and can be adapted for plant-specific applications using locally calibrated data.
