Abstract

The Hybrid Phenomena Theory (HPT) is a framework for formalizing how dynamic state space models of physical systems are built from first principles. The HPT descends from the Qualitative Process Theory (QPT), [Forbus, 1984], from which it inherits basic concepts like views, phenomena and influences. Howe_ver, the HPT redefines some of these concepts m a more strict manner in order to represent knowledge of physics with the accuracy .needed .to develop full parametric models. Specifically, Influences may specify quantified non-linear functions of several variables. A mechanism denoted subsumption is introduced to ensure consistency in the emerging models when different simplifying assumptions are made . The HPT has been implemented in CLOS.
