Rationale Capture and Reuse in Mixed-Initiative Planning

(Back to Manuela Veloso's home page.)

  • This project started in June 1995 as part of the ARPA Planning Initiative. Program Director: Tom Garvey.

  • We address mixed-initiative planning and learning from experience in complex adversarial domains,
    focusing on the Air Campaign Planning (ACP) task.

  • Our central objective is to integrate into a mixed-initiative planning architecture the ability to capture
    and creatively replay the derivation and the rationale underlying the joint human- and machine-based
    decision-making process while planning.

  • We expect to achieve significant reductions in plan generation time and improvements in plan quality
    over unaided human expert planners by rationale-driven (partial or full) reuse of past plans and subplans.
    The expert user can exploit the rationale at individual decisions or have the system offer entire pre-planned
    segments or strategies satisfying the requite rationale for the user to accept, reject or modify.

  • Throughout the year of 1995/96 we worked on a technology integration experiment to combine Prodigy/Analogy,
    as a fully automated generative and case-based planner with ForMAT (Mulvehill, Mitre), as a user-based
    case-based retriever. By June 1996, we achieved a real-time integration of the two systems,
    where Prodigy/Analogy and ForMAT communicate through message passing. Prodigy/Analogy observes
    the user's interaction with ForMAT, provides guidance from past similar plans and suggests
    modifications to be made in the new plan.
    This is a description of this technology integration experiment on rationale-supported planning in mixed-initiative
    planning, including an illustrative example from the demonstration.
