Abstract

This paper formalises the constraints governing the relationship between actions and their preconditions and effects in processes and plans. By providing axiomatisations and a model theory, we establish a sound basis for both deductive and constraint satisfaction-based reasoning. The constraints we present are expressed in a common ontology of classes and relations that is the basis of process and plan representations.
