| Application of an Expert System to Real Time Coil Transportation Control on an Electrical Steel Finishing Line Yoshinori Anabuki, Rintaro Owaki, Hideaki Sakiyama, Shigeru Nakazi, Takayuki Katae |

Synopsis : An expert system (ES)-assisted control has fully automated the operation of transportation facilities on an electrical steel finishing line at Mizushima Works of Kawasaki Steel. The system forms optimum schedules for transferring slit coils all on-line by 24 monorail-type coil carriers under its control. In order to obtain necessary response for real-time use, the control rules are divided into groups according to their functions, and only designated rule groups are made to run at one time, securing a response of less than 3s. The adoption of ES has enabled the system to successfully handle the complex operations of the line, and reduced man-months required for software development to one half compared with conventional programming language. The system has been working smoothly since its commissioning in March 1990 contributing greatly to the high-efficiency operation of the line. |
