1. A method for predictive recognition of errors in a manufacturing system, said method comprising the steps of:
- archiving a plurality of error patterns that previously occurred in the manufacturing system, the archived error patterns created by statistical methods;
monitoring manufacturing system data in real-time; and
comparing the monitored data with the archived error patterns in real-time to predict imminent errors likely to occur in the manufacturing system.

Abstract
Method, system and device for predictive recognition of errors in a manufacturing system, said comprising: online monitoring of data of the manufacturing system; and online comparing said data with archived error patterns to predict errors supposed to occur in the manufacturing system; whereby the archived error patterns are built and recognized by statistical methods and data mining methods. The present invention can be used for discrete or continuous or batch processes.
