Knowledge Development Methods for Planning Systems

Success in applying AI-based planning systems to real domains requires sophisticated methods of knowledge acquisition. Both interactive and automated methods are required: interactive methods to aid the user in entering planning knowledge; and automated methods to verify the interactively developed knowledge and extract new knowledge from a variety of sources, including simulators, on-line databases, training exercises, and actual situations.

We describe two knowledge development tools for a crisis action planning system. The first tool is a graphical operator editor that enables users to develop new planning operators and revise existing ones. The operator editor provides type- and consistency checking and incorporates methods for ensuring the syntactic validity of the new knowledge. The second tool is a largely automated inductive learning system based on the PAGODA learning model [desJardins 1992] that learns from simulator feedback and from choices made by the user during planning.
