Creating Planning Domain Models in KEWI

This paper reports on progress towards a tool for the representation of shared, procedural and declarative knowledge whose aim is to be used for various functions to do with the automation of a complex process control application primarily to guide the response phase during an emergency situation, but also for supporting normal automated operation. The tool is a Knowledge Engineering Web Interface called KEWI. The focus of the paper is on the conceptual model used to represent the declarative and procedural knowledge. The model consists of three layers: an ontology, a model of basic actions, and more complex methods. It is this structured conceptual model that facilitates knowledge engineering. We are aiming to evaluate the use of a central knowledge model for a range of planning-related functions, where the parts of the model are automatically assembled e.g. into PDDL for operational use.
