Gradual parameters are associated to identified entities (individual views and processes) and causal dependencies are expressed by means of two types of qualitative relations: influences, for direct effects of processes, and qualitative proportionalities, which propagate direct effects of proeesses on the other parameters. It follows that the initial cause of a parameter change is always a process. Qualitative relations can aim at opposite effects. In die physical situation of figure 1, the mercury expansion tends to increase the mercury level while the tube expansion tends to lower it. The first influence is predominant, since an increase of the mercury level is observed in that situation, and thus the second is inhibited 1. In order to represent different types of causal interactions, we...
