Abstract

The work presented here uses a library of behavior models of system components as a core for supportive tools for several work processes during the life cycle. Models of complex systems can be automatically composed from such library elements and provide the basis for the automated generation, instead of programming, of diagnostics and fault analysis. The feasibility of this model-based methodology is illustrated by case studies in the automotive and aeronautics industry. This includes a demonstrator for the automated generation of on-board diagnostics for a vehicle system. The same model basis is used to perform other tasks, such as failure-modes-and-effects analysis, diagnosability analysis, and the generation of tests.
