ABSTRACT:
A comprehensive, generic mechanism models, monitors, controls and optimizes manufacturing as an on-line, real-time system employing statistical analysis and mathematical techniques with feedback and forward information for local control and global optimization. Manufacturing is treated as a hierarchy of processes which are modeled, controlled, optimized and managed via four interacting networks; an application modeling network, a local control network, a global optimization network, and an implementation/management network. Of these four networks, only the application modeling network is application dependent. The functions of the other three networks are application independent. All manufacturing processes, from simple process steps through manufacturing sectors and lines, to complete factories, are treated identically, thereby simplifying computational complexity. A minimal set of parameters is thereby obtained at any manufacturing level, which reduces a complex manufacturing process to a manageable form. Outputs of lower level processes in the hierarchy become input process variables for higher levels. Process models are developed and updated via on-line data analysis, and are used to evaluate process status and improvement path.
