溶鋼編成システムの開発

抄録

In the steel industry, we organize ingots orders to molten steels which are manufacturing units. And this organization is called molten steel organization. Molten steel organization is a combination problem that considers multiple evaluations and manufacturing constraints and human have to spend a lot of time to adjust the initial solution obtained from the expert system. So we developed automatic molten steel organization system applied branch and bound to make multiple evaluation easy. We confirmed that good results such as productivity improvement are obtained compared with conventional approach.
