MANUFACTURING ENTERPRISE INTEGRATION USING HIERARCHICAL CONTROL AND DISTRIBUTED DATABASE

The advanced capabilities of computer systems and field sensory instru ments have lead companies to consider the use of computers, smart sens ors, and telecommunication networks. The application of a computerized system in a manufacturing and production environment includes data ac quisition, supervisory control, status monitoring, operation optimizat ion, and data management. A computer-automated and integrated manufact uring environment requires fast data sampling, high sensor capabilitie s, distributed control processing, reliable communication, easy-to-use software and operator interfaces. A computerized system should delive r the right information, to the right people, to the right equipment, at the right time. This system must use a distributed processing techn ique to achieve a comprehensive product and process quality monitoring , demand estimation and system monitoring and control while maintainin g overall cost at minimum. This paper proposes a layout of a distribut ed computer control structure for a computer integrated enterprise. It will also propose the supporting database associated with each level of this control hierarchy. It will also lists a set of activities and tasks associated with design and implementation of such automated syst em.
