Recently, mill wide information and control systems are gradually promoted in the pulp and paper industry in Japan. Oji Paper has installed and started up an integrated information system for the large-scale and complex pulp plant at its Tomakomai Mill. This system provides effective information to achieve higher quality and productivity, in the use of a super mini-computer with the real time linear programming technique, the relational data base and so forth. The system also has close connection with other systems such as the optimum energy management system, and lays the foundations for the mill wide system.
