    AIPS 2002 Workshop on
    On-line Planning and Scheduling
    Toulouse, France, April 2002

    Whereas the first automatic planning and scheduling systems were designed to
    run in an off-line setting (planning/scheduling and execution performed in
    sequence), current systems are frequently designed to run in an on-line
    setting (planning/scheduling and execution running concurrently).
    Application domains include manufacturing processes, supply chains,
    workforce organizations, power or communication networks, air or ground
    transportation, robot control, autonomous spacecraft, and unmanned air

    New requirements and new technical challenges arise in such a setting. Among

    * the planning/scheduling problem is no longer a static problem; it
    becomes a dynamic problem, with typically small changes in the definition of
    the instance to solve between successive calls to the planning/scheduling
    * new requirements appear, such as robustness and stability in the face
    of modeling uncertainties and unexpected events that may occur during
    execution; these requirements must be combined with the usual requirement of
    producing a plan/schedule of the best possible intrinsic quality;
    * hard and soft constraints on the time taken by the planning/scheduling
    function are introduced, requiring the planning/scheduling module to monitor
    and control its reasoning process;
    * it becomes necessary to take into account inside the
    planning/scheduling reasoning the time at which the plan/schedule will be
    provided and executed.


    Topics of interest
    The workshop will focus on these requirements and the various ways of
    satisfying them. Topics of interest include:

    * analysis of the on-line setting and of the new arising requirements;
    * planning/scheduling as a dynamic problem: methods and algorithms;
    * reactive planning/scheduling; repair-based planning/scheduling;
    * plan/schedule quality, robustness and stability: how to define, to
    combine and to optimize them?
    * planning/scheduling at various abstraction levels with various temporal
    * constraints on the time taken by the planning/scheduling function :
    what are they? how to set and to meet them?
    * control of the planning/scheduling reasoning; what trade-offs exist
    between quality and time?
    * reasoning about time and within time;
    * what trade-offs exist between off-line and on-line computing?
    * task sharing and interactions between the planning, scheduling, and
    execution functions;
    * validation and assessment of an on-line planning/scheduling system;
    * real-world on-line planning/scheduling applications; selected
    approaches, implementation issues, experimental results, comparisons between
    approaches or implementations.


    Authors are invited to submit either long papers (approximately 8 pages), or
    short position papers (1-2 pages). Papers must be written in English. They
    must be submitted as Postscript, PDF, or Word files. They must be sent to
    the program chair by the 11th of February, 2002, preferably by electronic
    mail. If electronic submission is not possible, please send 3 copies by
    surface mail. The first page of the submission must indicate clearly the
    contact author and provide complete contact information.

    Each paper will be reviewed by at least two members of the program
    committee. Decisions of acceptance or rejection will be sent electronically
    to the contact author by the 11th of March.

    In case of acceptance, the final version will have to be sent by the 25th of
    March. Final versions will be included in the working notes of the workshop
    and made electronically available on the workshop web site.

    At least one of the authors is expected to attend the workshop and to
    present the paper. All the workshop participants are also expected to
    register to the AIPS2002 conference.

    Workshop organization
    The workshop will take place the 24th of April, 2002. It will be both
    an AIPS 2002 workshop and a workshop of the TCU (Technical Coordination
    Unit) On-line Planning and Scheduling of the PLANET network (European
    Network of Excellence in Artificial Intelligence Planning).

    To encourage interaction, each presentation will be followed by a short talk
    of one of the program committee members, the role of which will be to
    critique some of the proposals, highlight some positive or negative aspects,
    ask questions, and enliven the debate.
