In this study, we formulated the scrap compounding problem in the electric furnace steelmaking method as a multi-objective mixed integer linear programming problem, and tried to derive multiple Pareto solutions from viewpoint of multi-objective. In the verification experiment, we compared it with the conventional manual formulation, and confirmed that the formulation results obtained in this study had the same or higher quality.}, title = {多目的スクラップ配合問題に対する解法とその解分析}, year = {2021} }
