Modeling the Rats in the Basement Or: Representing \ablers" Knowledge in Qualitative Compartmental Models Modeling the Rats in the Basement Or: Representing \ablers" Knowledge in Qualitative Compartmental Models

There are rats in the basement. When they scurry around, they knock the fuse box and short out the power supply. Consequently, only if the rats are absent today does icking the light switch turn on the lights. This article discusses the use of a simple and-or graph representation to handle such abler statements in qualitative compartmental modeling framework. Abstract There are rats in the basement.
