Abstract

In this necessarily very brief review, a motivation for the use of qualitative causal descriptions of physical systems is presented. Some of the commonalities of the developing themes of qualitative modelling are presented, namely: a qualitative description represents a set of open intervals separated by boundaries corresponding to the occurrence of 'significant' events. The reasoning based on these models was outlined for the case of qualitative mathematics (Kuipers) and qualitative physics (de Kleer). The main difference being in the way the model is obtained. In the case of Kuipers it is directly obtained from the quantitative differential equation, whereas in de Kleer's approach the equations come from an application of physical law to individual components of a device.
