Integration of business and production levels in process industries

摘要

Process control Systems are operated more or less in isolation from business systems relating to the same plant. As the potential benefits of integration have become clearer. there have been several attempts to link process control and business control systems. One aspect of linking is described in this paper. A primary function of a process control system, which was in 1996 successfully installed in a Slovenian brickwork. is brickwork, is efficient control of the drying process in the factory, and so far this system is conceived as a classic computer-based process control system. With regard to the possible need to incorporate this control system into a future CIM information system, a concept of flexible recipes was applied as a possible integration link between planning. which is a typical business-level activity, and process control, which is a production-level activity. Flexible recipes thus may provide a modest contribution to the integration of shop floor control and logistical functions.
