Diagnostic model of an object describes the relations between observed symptoms and their causes, i.e. the technical states of the object. Direct specification of such models is (quite) impossible due to the complex nature of these relations. This paper aims to inform the reader about the general idea of inverse diagnostic models. A special attention has been drawn to the application of known cause-effect dynamic models of investigated objects. Such models transform features of technical states into diagnostic symptoms. Their numerical inversion makes it possible to identify the global as well as local diagnostic models, with the latter ones being more appropriate. Local models have interesting features, but they require experienced users and sophisticated computing techniques. General methods for their identification are still being developed. An interesting idea is connected with the possibility of considering such local models as example based models, i.e. models spanned on particular sets of pattern data.
