Model based reasoning about physical systems deals with diagnosis, supervision, interpretation, explanation, etc. Most of the contributions to this domain do not pay much attention to model construction, and it was generally accepted that a model was available or could be easily obtained. This assumption is no more valid when we tackle real industrial problems rather than toy examples. The situation is even worst since there is no standard methodology or approach to making models. In this paper we provide a framework to elaborate models which are suitable for model based reasoning in general, and for fault diagnosis in particular. The framework relies on the bond graphs notation, which allows a uniform approach for the different physical domains and offers compositional view of the system.
