A method automatically recovers from a fault situation in a production plant and provides production resources and a manufacturing execution system having a production modeler for modeling the production resources into a plant model and a production scheduler to schedule operations of the modeled production resources. A production controller executes the production process and a fault manager detects fault situations and automatically decides a corrective action. A production resource runs an application for the operation of the production resource and a fault analysis agent provides categorized error situations and checks operational data representing the operation of the production resource against the categorized error situations and when, an error situation occurs, forwards an error event to the fault manager. The error events are collected and then analyzed by a neural network system to assign the error event to an error category. A corrective action is executed on the production resource. |
