Blast Furnace Control by Artificial Intelligence

Abstract Kawasaki Steel Corporation has recently developed a new blast furnace control system adopting an expert system, a kind of artificial intelligence technology. Knowledge representation in this system is designed to reflect knowledge structure of experts with fidelity, and is written in production rules. It is practiced in an engineering work station for exclusive use of AI, and gives operation guidance to operators every five minutes. Evaluation of this system was made by comparing operators and this system in terms of judgment in actual operation, and good results were achieved.
