Hybrid Planning: An Approach to Integrating Generative and Case-Based Planning


desJardins, M. and Francis, A. and Wolverton, M. Hybrid Planning: An Approach to Integrating Generative and Case-Based Planning, in Case-Based Reasoning Integrations: Papers from the 1998 AAAI Workshop, AAAI Press, 1998.


This paper describes ongoing research on the development of a hybrid planning system that integrates case-based reasoning (CBR) methods into SIPE-2, a generative planning system. Novel aspects of this work include the integration of CBR methods with a hierarchical task network (HTN) planner; the estimation of adaptation cost based on a classification of planning conditions; the reuse of plans using SIPE-2’s replanning techniques; the extraction and application of advice from retrieved cases to guide planning in a form of plan replay; the representation and use of opaque constraints, which describe the human planner’s decision factors; and the provision of case-based support for managing a distributed, continuous planning process.
