Domain and system influences in problem solving models for planning

The field of knowledge level modelling has achieved great success when applied to various domains, yet has thus far largely neglected the generic areas of planning, scheduling and resource allocation. In this paper we outline the development and use of a knowledge level modelling approach within the domain of planning for Search and Rescue. Existing problem solving models for planning are almost exclusively derived from the analysis of systems. We argue that this makes their suitability for directly assisting knowledge acquisition debatable. Our approach makes a clear distinction between domain derived knowledge level models and those derived from systems. We describe how the combination of these two types of model can achieve definite: benefits within the course of KBS development.
