ABSTRACT:
A method for identifying a state of a manufacturing system includes defining at least one virtual sensor having a value. At least one state descriptor including a plurality of condition terms and a trigger probability is defined. Each condition term includes a function of the value of the virtual sensor. The condition terms are evaluated based on the value to determine a classification probability. The state is identified responsive to the classification probability being greater to or equal to the trigger probability. A manufacturing system including a plurality of tools, at least one virtual sensor, and a state classification unit is also provided.
