*===================================*
This workshop continues a regular series started in October 1997 at
Oxnard, California and continued in San Francisco (2000) and Houston
(2002). The fourth workshop will be held for the first time in Europe and
is focused on the many challenges facing the Planning and Scheduling
community in meeting the broad needs of space applications. Previous
meetings have highlighted the need for advanced Planning/Scheduling
capabilities in the space domain and the limited success with technology
infusion into ESA and NASA missions. Further, the missions that various
space agencies are contemplating in the near future will require
significant levels of autonomy on the ground and onboard vehicles, which
will be deployed in harsh environments. The costs, complexity, and
duration of these missions have been on the rise, requiring significant
support from automated tools and techniques. While these would have
nominally resulted in further deployments of autonomous systems in such
mission critical environments, we have yet to see Planning/Scheduling
systems make substantial inroads into the space community. The aim of
this workshop is to understand the state of the art in P&S problem solving
techniques, the current state of the art in real space missions, and to
encapsulate the challenges that lie ahead.
Key issues in P&S technology for space include:
-- Domain representation and acquisition: The task of representing the
knowledge needed to perform the critical task of a mission and, in
particular, the relevant constraints for building domain knowledge for
planners/schedulers. Open issues include the integration of causal
planning knowledge with temporal and resource information, knowledge
engineering tools for supporting knowledge extraction and verification,
ontologies for P&S in space, and incremental refinement tools that
guarantee continuous operational support in the space domain.
-- Applicable algorithmic methods: Given the limitations of hardware
platforms and response times in harsh environments, a key open issue is
how to plan with causal, temporal and resource knowledge in such a way as
to address scalability in the size of the problem, on-line computational
time bounds, and the synthesis of plans that can be robustly executed.
-- Plan verification: How do we verify that the synthesized plans are
correct? Validating the behavior of an automated planner/scheduler in an
operational context is a major challenge. Different approaches are
possible and are worth comparing to see how they can scale to the kinds of
applicable problems in this domain.
-- Applicable embedded architectures: A key role in space is played by
closed loop P&S architectures. In fact, agent architectures that deal
with autonomous operations of spacecraft are a crucial tall pole in
fielding P&S systems. These architectures highlight all of the issues
above as well as the following issues: software engineering approaches to
building robust commanding systems, uncertainty management, fault
diagnosis and execution, contingency approaches to commanding and failure
recovery among others.
The aim of this workshop is to discuss these and other related issues in
the context of space missions and applications. We welcome papers that
offer insight into these, and other, planning and scheduling challenges.
We especially welcome papers that describe deployed applications of
planning and scheduling technology within space or space-relevant domains
and papers that describe requirements for planning and scheduling in
future missions. Example applications include: spacecraft commanding and
payload operations; planning and scheduling for process control; planning
and scheduling for robotic space activities; operations of air, space and
ground-based scientific observatories; scheduling of critical resources on
the ground and on-board; science data analysis; design and analysis of
spacecraft systems; planning and scheduling of scientific experiments; and
planning and scheduling of crew activities. We also welcome papers on new
planning and scheduling technology that may be applicable to space domains
and papers that integrate planning and scheduling with other techniques,
such as verification and validation, machine learning, task execution, and
fault detection and diagnosis. Additionally the workshop will highlight a
special topic on:
-- On-ground vs. on-board P&S technology: Space programs are divided into
ground and flight segments. P&S techniques have been shown to be
potentially very useful as a support tool in the ground segment (e.g.,
AMM, MAPGEN, MEXAR) and in the flight segment (e.g., DS1 Remote Agent, the
EO-1 Sciencecraft). While the two extremes rely on the same core
technology, they potentially satisfy different needs. For example, issues
like the interaction with users for on-ground applications satisfy
completely different requirements with respect to the problem of
developing an embedded closed loop application for an on-board
architecture, but both may rely on the same P&S core. Indeed, an issue of
further discussion includes the rationale and design features for
distributing P&S technology in mission sub-components while taking
advantage of the common core technology. We encourage papers that shed
light on the key differences/commonalities on this topic and also that
report real experience and challenges from the field.
Workshop Organization
---------------------
This workshop will strive to bring together technologists, researchers,
and end-users of planning/scheduling technology. To encourage interaction
among these groups, we will continue the commentary format of the previous
workshops. The program committee will review all submitted papers for
acceptance at the workshop. Accepted papers will be further categorized
into plenary and poster presentations. For each of the plenary papers, a
commentator will be selected from a different community than that of the
paper's authors. The commentator will be encouraged to have a dialogue
with the authors and will then write a short commentary on the paper,
which will be presented with the paper and will be published in the
proceedings. The commentary is not a review or critique, but simply a way
to encourage interaction between different communities. Papers selected
for poster presentations will also be published in full in the
proceedings, although they will not have a commentary. The workshop will
also include panel discussions, invited speakers, and tours of ESOC. A
separate space will be dedicated to demo sessions on P&S techniques and
space applications. Demos can be related to a paper but need not be
necessarily. In the latter case, a two page demo proposal must be
submitted following the same procedure as for normal papers.
