操作人员的经验和知识对高炉的运行控制很重要。在新日铁金光厂3号、4号高炉上实际应用了能够代表这一经验知识的知识工程或专家系统。在专家系统知识库的开发中，采用由传感器信息判断、中期判断、最终判断和动作阶段组成的假设推理方法来表示最有经验的操作人员的知识。专家系统的实现重点是操作员的可维护性。为此采取的措施包括采用日语生产语言，增加推断结果的指示，安装离线终端修改和测试运行知识库。由于这些努力，专家系统可以在很大程度上由现场人员操作和控制。自从专家系统上线以来，定期召开研究会议，评估其性能并更新知识库。利用专家系统对两座高炉进行了快速的实际运行控制，保证了高炉的稳定运行。
The experience and knowledge of operators are important for operation control of blast furnaces. A knowledge engineering or expert system that can represent this empirical knowledge was practically applied to Nos. 3 and 4 blast furnaces at Kimitsu Works, Nippon Steel Corp. In the development of the knowledge base for the expert system, the knowledge of the most experienced operators was represented by a hypothetical inference method composed of the sensor information judgement, interim judgement, final judgement and action stages. The expert system was implemented with emphasis placed on its maintainability by operators. Among the measures taken to this end are the adoption of a Japanese production language, augmentation of indication of inferred result, and installation of off-line terminals for modifying and test running the knowledge base. As a result of these efforts, the expert system can be largely operated and controlled by the field personnel. Since the expert system was brought on-line, periodic study meetings have been evaluating its performance and updating the knowledge base. The expert system is utilized in the actual operation control of the two blast furnaces at a high rate and the blast furnaces are stably operated.
