Early work on the NONLIN and O-Plan projects indicated a need for a defined methodology which would guide users performing various roles in the acquisition and analysis of domain requirements for planning. This work included links to a requirement analysis methodology, CORE (COntrolled Requirements Expression) , tool support via an intelligent assistant as part of the Task Formalism (TF) Workstation and an initial collection of guidelines and checklists to aid in using the TF domain description language. This paper describes work underway to follow-on from this past research and to infuse it with knowledge gained from recent research related to planning domain development, knowledge modelling, design rationale and ontological and requirements engineering. Introduction The activities involved in discovering, engineering, documenting, and maintaining a set of domain constructs for most AI planning-based projects can be considered ad hoc and disorganised, at best. The current sources for...

The world of business and organised work is changing. This change is driven by a shift of organisational focus away from individual fragmented tasks toward an examination of the holistic processes. New tools are being developed to assist individuals in building, evaluating, and managing these processes. The application of these tools though must be holistic as well. Organisational knowledge management should be structured in a way that encourages exchange of process knowledge. In order to e ectively share information, we believe theremust be an explicit account ofwhat knowledge will be exchanged, a shared understanding. We approach thisbyproviding an extensible ontology which presents process related concepts and terminology which are common to a range of applications and industries.

This paper describes a design space analysis approach towards a "complete" planning solution. A complete solution is defined as one containing the resultant plan, the context in which it applies, and the argument structure that justifies it. The focus in this paper is on defining and communicating the argument structure component. A perspective of a plan as a specialised type of design and planning as a specialised form of design activity is used. In doing so, research is drawn upon from the design rationale community for generating an explanation of a designed artifact. In particular, the method of generating a design space which represents the location of the plan within the space of possible plan elaborations is adopted. An initial implementation, Nonlin+DR, is described and its potential benefits to stand-alone and mixed-initiative planning is discussed. Introduction The traditional solution produced by an artificial intelligence planning system is a set of actions and ordering co...
