A step toward reusable model fragments.

In this paper we describe a system to elaborate models which are suitable for model based reasoning. A set of model fragments selected from a library will be put together to build a model candidate. The system relies on the bond graph notation, which allows a uniform approach for the different physical domains and offers a compositional view of the system. Modeling requires the exploration of a search space of potential model candidates. These models are checked to be consistent with a set of behavior constraints and modeling hypotheses provided by the user.
