Abstract:
1. A method for automatic generation of an extended fault tree structure adapted to one of a production installation type and a specific production installation within a system for determining an overall equipment effectiveness for the specific production installation type or for the production installation, which comprises: providing a data processor having stored programs and data stores including a fault database, a fault tree memory, and a verification script memory; entering fault events in the fault database one of through a data input and determined from data called up from a data server; storing, with the data stores: generating, based upon the prescribed general hierarchical fault tree structure, the extended fault tree structure by carrying out functions of a hypothesis verifier, a fault data classifier, and a hypothesis configurer with the data processor and the stored programs; entering and altering fault hypotheses with a hypothesis editor; and producing the extended fault tree structure by:
