....the construction and use of the qualitative model. And finally, in section 7 we evaluate our case study in retrospect, trying to answer the questions posed above. 2 Representational Context The model of this paper is implemented in a domain independent qualitative reasoning shell called garp (Bredeweg, 1992). Garp incorporates many features of the componentcentered (de Kleer and Brown, 1984) and the process centered (Forbus, 1984) approaches in QR. Initial conditions are described in case models, the theory itself in model fragments (consisting of conditions and givens) Case models and model ....

....constituent types. These are physical phenomena which are considered to contribute to the behavior of the overall system. They can represent basic component laws (Ohm s Law, logical or) or processes in QPT ( Forbus, 1984] such as chemical stratification, or partial behavior models like in [Bredeweg, 1991]. They occur deterministically under certain conditions, and their occurrence generates particular effects. Applying the distinction between structural aspects and the characterization of behavior through quantities to both conditions and effects, we obtain STRUCT CONDS QUANT CONDS ....

....3 Modelling Primitives 4 Tasks in Qualitative Model Construction This section describes sonhe important aspects of the framework for qualitative predic tion of behaviour that we use. This frame work is implemented as a donhain independent qualitative reasoning shell called CARP [Bredeweg, 1992]. Similar to the component [de Kleer and Brown, 1984] and the process oriented approach [Forbus, 1984] CARP uses the notion of model fragments for deriving the behaviour of sonhe real world device. All model fragments have associated with them a set of conditions under which they are applicable ....
.... initial model (without knowledge about assembly specific behaviour) that was used by the qualitative prediction engine (GARP) resulted in 179 derived states of behaviour (total envi sionment) The first specification step (find ing all sets of model fragments that apply to the input system) cf. [Bredeweg, 1992]) produced already 15 states, 14 of them being spurious. Only the state with number 11 was valid, for more details see [Bredeweg and Schut, 1993] Note that no spurious states are produced if the generated constraints are added to the model. Once the appropriate constraints have been determined, ....

....for qualitative prediction of behaviour. Various shells exist in which, in principle, the behaviour of different physical systems can be analysed by only specifying the structural constellation of the system and some initial values (e.g. ENVISION, QPE, QSIM (Weld and de Kleer, 1990) GARP (Bredeweg, 1992)) We aim at a learning environment that exploits the generic nature of qualitative reasoning systems. The resulting environment should ideally be able to teach about the behaviour of a physical system for which an initial description of structure and state (the so called case model) is provided. ....
