1. A method, comprising:
- defining a first fault model associated with a first node of a first level of a manufacturing system;
defining a second fault model associated with a second node of a second level of the system;
defining a third fault model associated with a third node associated with a third level of the system, where the second and third levels are lower than the first level;
processing workpieces in the manufacturing system;
receiving operational data associated with the processing of the workpieces;
anddetermining a health value associated with the first node based on applying at least a portion of the operational data to the second fault model and applying at least a portion of the operational data to the third fault model.

Abstract
A method and apparatus are provided for determining the health of a desired node in a multi-level system. The method includes defining a first fault model associated with a first node of a first level of the system, defining a second fault model associated with a second node of a second level of the system, and defining a third fault model associated with a third node associated with a third level of the system. The method further includes determining a health value associated with at least one of the first node, the second node, and the third node of the system based on at least one of the first fault model, second fault model, and the third fault model.
