A METHOD AND APPARATUS FOR PERFORMING A MODEL-BASED FAILURE ANALYSIS OF A COMPLEX INDUSTRIAL SYSTEM

摘要

For performing a model-based failure analysis of a complex industrial system including hardware and/or software components each represented by a context independent component model interface terminals and a set of component behavior modes including a normal mode and failure modes of the respective component stated as constraints on deviations, is provided. This method includes generating a system model, SM, of an investigated industrial system by loading component models of the components of said investigated industrial system from a component library and connecting the interface terminals of the loaded component models according to a structure of the investigated industrial system and executing a constraint-based predictive algorithm on a reasoning engine to generate qualitative FMEA results for different operation scenarios, OS, of the investigated industrial system.
