Abstract
The present invention configures a control strategy and a process model to calculate a setting of a machine. The present invention adjusts the process model in accordance with an analysis of the setting to control the machine.
Claims19
An apparatus for controlling a factory, comprising:
- circuitry for configuring a plurality of process models;
- circuitry for configuring a plurality control strategies;
- circuitry for selecting a process model from said process models and for selecting a control strategy from said control strategies;
