Modem manufacturing systems involve many processes and operations
that can be monitored and controlled at several levels of
intelligence. At the highest level there is a computer that
supervises the various manufacturing functions, whereas at the
lowest level there are stand alone computer controlled systems of
manufacturing processes and robotic cells. Until recenty
computer-aided manufacturing systems constituted isolated "islands"
of automation, each oriented to a particular application, but
present day systems offer integrated approaches to manufacturing
and enterprise operations. These modem systems, known as
computer-integrated manufacturing (CIM) systems, can easily meet
the current performance and manufacturing competitiveness
requirements under strong environmental changes. CIM systems are
much of a challenge, and imply a systemic approach to the design
and operation of a manufacturing enterprise. Actualy, a CIM system
must take into account in a unified way the following three views :
the user view, the technology view, and the enterprise view. This
means that CIM includes both the engineering and enterprise
planning and control activities, as well as the information flow
activities across all the stages of the system.
