Patent ID: 7100093

Claim:
A method for an automated determination of fault events by evaluation of field data of a production installation within a system for determining an effectiveness of the production installation and for an analysis of causes of faults, which comprises the steps of: providing a data processing device having a fault event detector, an overall equipment effectiveness (OEE) script configurer, and programs stored therein for carrying out functions of the fault event detector and the OEE script configurer, the data processing device further including a fault database for storing determined fault events and an OEE script memory, the OEE being defined as a multiplication of synergistic parameters; determining fault events by the steps of: using the OEE script configurer to access a prescribed productivity model specific to the production installation, generate an OEE script with likewise prescribed configuration data taken into account, and store the OEE script in the OEE script memory; and using the fault event detector to access the OEE script, call up the field data from a data server of the production installation according to execution requirements of the OEE script, derive the fault events from the field data according to processing instructions of the OEE script, and store the fault events together with previously entered fault events, in the fault database; and analyzing causes of faults.
