A management information system based on a high-speed data link and microcomputers

Abstract

Co-ordinating the various unit processes in an integrated pulp and paper mill is a very complicated task. Many attempts have been made to facilitate plant-wide overall control by using computer techniques. The approaches employed have usually been centralized with the emphasis on production planning and control. Difficulties have often arisen because of the complexity of the overall problems.The approach presented in this paper is based on the use of a high-speed data link. All connections to the data highway are managed by microprocessors. Typical units connected to the system include process control packages, inventory, maintenance and other computer systems, data capture devices, color display terminals, and order entry and production planning packages based on data base management systems. All data transmitted is available to every unit. Intelligent color display terminals are used to display the data desired at a particular point of the process.The design of the management information system is based on the belief that the key to the benefit of the system lies in transmitting the right information in the right form to the right place. This is achieved with the data highway and color terminals. If desired, planning functions can be added to the system.
