                          CALL FOR PARTICIPATION

              Workshop on: PLANNING AS COMBINATORIAL SEARCH:
       PROPOSITIONAL, GRAPH-BASED, AND DISJUNCTIVE PLANNING METHODS

                           Sunday, June 7, 1998
                        Carnegie Mellon University
                              Pittsburgh, PA

                            in conjunction with
                    Fourth International Conference on
            Artificial Intelligence Planning Systems (AIPS-98)

DESCRIPTION
-----------

Recently very efficient planning systems have been build around local
search, graph search, A* search, dynamic programming, integer
programming, and other general combinatorial search techniques. This
workshop will examine the common threads that link these different
efforts and look for new ways that mature combinatorial algorithms
from different areas of computer science can be fruitfully applied to
AI planning systems.

Some of the issues we will discuss include:

* Tradeoffs in translations of planning problems into other
formalisms, such as propositional satisfiability or integer
programming.

* Unifying frameworks, such as disjunctive planning.

* Comparisons of general search engines and specialized planning
systems. Cross-disciplinary benchmark test-beds.

* The role of heuristic and domain-specific knowledge when the
"planner" is a general combinatorial search engine.

* The relationship with the kinds of representations used in
model-based planning and diagnosis, and those used by systems such as
SATPLAN or Graphplan.

* Comparing the use of classic optimization techniques in planning
with uncertainty to the use of those techniques in state-space
planning.

For more suggestions on unifying frameworks and problem encodings, see
the home pages for the IJCAI-97 Challenges in Bridging Plan Synthesis
Paradigms (http://rakaposhi.eas.asu.edu/challenge.html) and
Propositional Reasoning and Search
(http://www.research.att.com/~kautz/challenge) respectively.

WORKSHOP FORMAT
---------------

The workshop will include panels, invited talks, discussions, and
breakout sessions. We will identify several major common themes for
panels and breakouts based on the research statements from
participants (see below), and will select people to make brief (5
minute) presentations on their work as part of the discussions.

                          CALL FOR PARTICIPATION

        Workshop on: INTEGRATING PLANNING, SCHEDULING AND EXECUTION
                   IN DYNAMIC AND UNCERTAIN ENVIRONMENTS

                           Sunday, June 7, 1998
                        Carnegie Mellon University
                              Pittsburgh, PA

                            in conjunction with
                    Fourth International Conference on
            Artificial Intelligence Planning Systems (AIPS-98)

          http://wwwagr.informatik.uni-kl.de/~bergmann/AIPS98WS/

Motivation:
-----------

Integration of planning, scheduling and execution is an increasingly
important area of research. We are starting to see the deployment of
planning/scheduling systems, robotic and software agents in domains
such as manufacturing, information retrieval, transportation, military
operations, and space explorations. They all function in dynamic,
uncertain, and incompletely known environments.

Planning/scheduling systems and agents must often function in
highly dynamic and uncertain environments in which objectives, demands,
and resources change rapidly due to the influences of the environment,
and the actions of friendly, neutral, and hostile agents.
Such situations pose a number of challenges to planning/execution
systems. They must interleave planning, scheduling, and execution,
and must do so in a way that takes account of the passing time. They
must form plans and schedules that are robust with respect to changes
that can be anticipated as likely to occur. And they must be able to
modify previously formed plans and schedules, in compliance with the
most recent available information, attempting minimum disruption of
earlier plans and still aiming for the most effective possible use of
resources and achievement of goals.

Workshops at previous conferences have demonstrated that there is
already considerable work in this area. Now, the time is ripe to
explore this area in more depth by bringing together different
researchers.

Workshop Topics:
----------------

-- Rigorous formulations of the planning/scheduling/execution problems
   in dynamic and uncertain environments.

-- Ontologies and representations: How useful are the ontologies and
   representations (of plans, actions, and planning problems) that have
   been developed for static or certain domains?

-- Models, algorithms, and architectures for planning/scheduling in
   dynamic and uncertain environments:
   - interleaving planning, scheduling, and execution;
   - planning and execution with incomplete and uncertain information;
   - managing limited computational resources;
   - forming plans that are robust with respect to changes;
   - using cost models in the context of planning and execution.

-- Learning issues:
   - How can one exploit information from execution failures/successes,
   - How to reuse planning and execution experience, e.g., case-based
reasoning?

-- Real-world applications and implemented systems:
   - descriptions of real-world applications and lessons learned;
   - real-world requirements for the integration of planning and
execution;
   - new promising application domains;
   - evaluation criteria.

Introduction
------------

There are many planning techniques and algorithms around. However, for
someone who wants to engineer a practical planning system for a particular
domain, it is not that straightforward to select which technique or
algorithm to use. If we want sophisticated planning research to find its way
into the real world, we have to provide concrete support for engineers of
planning systems to bridge the gap between theory and practice. Such support
can take the form of guidelines for relating planning techniques to
particular domains, re-usable libraries of plan domain descriptions,
plan/process editors, knowledge acquisition tools to analyze and model
planning problems, tools to configure planners from reusable planning
components, etc. In order to come up with such support, a deep understanding
of planning is needed. We therefore invite authors to submit papers on
topics including, but not limited to:

   * Analysis of knowledge used in planning (domain knowledge,
     problem-solving knowledge).
   * Ontologies and schemas of plans and planning processes, and their use
     in knowledge acquisition and engineering.
   * Reusable and modular planning components.
   * Case studies reporting on the knowledge engineering and acquisition
     process of constructing planners for concrete applications.
   * Relations between characteristics of domains (domain features) and
     planning techniques or planning problem-solving methods (also called
     assumptions of problem-solving methods).
   * Why are some representation techniques (e.g. HTN, ADL-operators,
     fluents) more natural for particular domains than others?
   * Knowledge acquisition tools for planning (including software demos).

Working notes of accepted papers will be distributed at the workshop, and
will also be made available on the Web. Selected papers will be considered
for journal publication (e.g. in a special issue).

Workshop Format
---------------

The workshop format will consist of three parts: (1) informal paper
presentations and discussions, (2) discussion groups about issues raised
during the first part, and (3) demos of software tools for knowledge
acquisition and engineering.

Submission of Papers
--------------------

Submissions should be maximum 15 pages long, of which the first page has to
include at least authors, affiliation and email address of the contact
person. Electronic submissions are highly preferred, either in postscript or
HTML. To submit, simply email the URL of the paper to the contact person.
Alternatively, a postscript file can be emailed to the contact person. For
submissions in hard copies, please contact the contact person. Deadline for
submission is March 3, 1998. LaTeX users should use the switch: latex2html
-split 0 -show_section_numbers for generating the HTML version.

                          CALL FOR PARTICIPATION

            Workshop on: INTERACTIVE AND COLLABORATIVE PLANNING

                           Sunday, June 7, 1998
                        Carnegie Mellon University
                              Pittsburgh, PA

                            in conjunction with
                    Fourth International Conference on
            Artificial Intelligence Planning Systems (AIPS-98)

The AIPS-98 workshop on Interactive and Collaborative Planning will
bring together researchers from Computer Science and related fields to
discuss the foundations, trends, and future prospects for building
planning systems that interact and collaborate with people.

Planning has long been a key problem for AI research. Recent
technological developments are making it possible to build planning
systems in realistic domains that can solve hard problems quickly.
Nonetheless, there seems to be a clear need to integrate these
automated systems with the abilities of human planners and
decision-makers. There will always be problems that are too hard for
the automated planners to solve, or for which it is too difficult for
the human users to formulate their requirements precisely enough for
the automated systems to use effectively. Even in planning systems
with more autonomy, issues of tasking, authority and reporting require
that these systems interact with humans at some point. Thus having the
human ``in the loop'' is both a practical necessity and an
intellectual opportunity. The ultimate goal of interactive and
collaborative planning systems is for humans and computers working
together to be able to solve harder problems than either could solve
alone.

This workshop is focussed on planning and related types of
problem-solving involving action and time, rather than general
human-computer interaction. Topics of particular interest include, but
are not limited to:
  - Mixed-initiative planning
  - Incremental planning
  - Plan visualization
  - Plan explanation and exploration
  - Architectures for interactive planning systems
  - Collaborative environments and mechanisms
  - Use of existing planning technology in interactive and
    collaborative systems
  - Advanced I/O modalities for planning (speech, gestures, maps,
    GUIs, etc.)
  - Interleaved planning and execution (online planning)
  - Automated support for groups of human decision makers
  - Use of planning and plan recognition in collaborative systems
  - Integration of planning and information gathering (situation
    assessment)
This list is not meant to be at all restrictive. Researchers from all
disciplines are encouraged to share their ideas on interaction as they
apply to planning.

Persons wishing to participate in the workshop may submit either
full-length papers (of at most 8 pages) or 1-2 page position papers in
AAAI conference format. Full-length papers will be presented in full,
time permitting. Participants submitting only position papers will be
organized into panel discussions based on their interests, at the
discretion of the organizers. Demonstrations of interactive and
collaborative planning systems are particularly encouraged, provided
suitable logistical arrangements can be made. Submissions should
clearly indicate any such requirements.

Submissions should consist of three (3) copies of full-length or
position papers and must be received at the address below no later than
Friday, February 20, 1998:
        Dr. George Ferguson
        Dept. of Computer Science
        734 Computer Studies Bldg.
        University of Rochester
        Rochester, NY, 14627-0226
Fax or email submissions will not be accepted. Authors will be
notified of acceptance by April 1, 1998.
