               Call for Participation
2nd International NASA Workshop on Planning and Scheduling for Space

                March 16th to 18th 2000, San Francisco
                        California, USA

This meeting is the second in a regular series started in October 1997
at Oxnard, California. Since then, the importance of automated planning
and scheduling for the space enterprise has become increasingly
clear. NASA technologists and computer scientists have also demonstrated
the practical feasibility of these technologies in the context of real
missions. For example, the Deep Space 1 Remote Agent Experiment in May
1999 for the first time demonstrated the use of a planner/scheduler
operating within the high-level closed-loop control of a spacecraft
traveling in interplanetary space. However, to make Planning and
Scheduling a ubiquitous technology for space missions, many challenges
still remain, including issues in design, development and fielding of
such systems in mission critical areas of spacecraft operations. For
* Responsiveness: When operating within a closed-loop control system,
  issues related to responsiveness and balance between deliberation and
  reactivity become more and more important. So far we do not have good
  answers on how to coherently insert planning activities with different
  reactivity guarantees at the different levels of an optimizing,
  hierarchical control system.

* Validation: Validating the behavior of an automated planner/scheduler
  in an operational context is a major challenge. An automated planner
  makes it possible for a system to adapt its actions to changing
  execution conditions. However, we still do not know how to guarantee
  that a plan generated in a previously untested situation will indeed
  operate the system correctly and safely.

* Mixed-Initiative autonomy: As planning systems become an integral part
  of mission operation concepts, it becomes crucial to solve the problem
  of guaranteeing a seamless collaboration between automated schedulers
  and human operators. This includes support for variable levels of
  autonomy, representational formalisms for doing mixed-initiative
  reasoning, resolving conflicts between operator requests and existing
  plans or flight rules and providing the operator with explanations or
  insight into the behavior of the planning system.

* Mission acceptance: Gaining acceptance of planning and scheduling
  technology for real missions requires balancing the promise of
  advanced technology with the need for safety and reliability. The
  underlying representation, algorithms, interface with existing tools,
  and user interface all play important roles in the final usefulness
  and usability of the technology.

This workshop aims to debate these and other issues in the context of
space missions and applications involving both completely automated
systems and those with human intervention in the exploration of
space. Within this area, planning and scheduling is important in (but
not restricted to)

* Spacecraft commanding and payload operations;
* Operations of air, space and ground based scientific observatories;
* Scheduling of critical resources whether on the ground or onboard;
* Science data analysis;
* Design and analysis of spacecraft systems;
* Planning and scheduling of scientific experiments;
* Planning and scheduling for life support systems;
* Operations and payload scheduling for space transportation systems.

To guarantee a lively debate grounded in actual operational needs, the
workshop will bring together:

* Researchers addressing basic research relevant to realistic
  applications for space;

* Technologists working on planning and scheduling applications for

* Mission representatives that have direct experience with planning and
  scheduling technology or want to contribute in formulating problems
  and requirements for the area.

To foster a lively and intensive interchange of ideas between the
different groups, paper selection to this workshop will follow a
slightly different process than the previous workshop.

Papers will be submitted to the program committee by the submission
deadline. The program committee will perform a preliminary review of
papers for acceptance to the workshop and for each selected paper
suggest an additional commentator, explicitly selected from a different
community than that of the paper's authors. For example, a basic
research paper may be assigned to an individual who is active in the
development of applications or in mission operations. Authors should
therefore ensure that paper submissions are understandable and contain
adequate background material for the commentator. The commentator will
then be asked to write up a short write-up on the paper and encouraged
to have a dialogue with the paper's authors either via e-mail or through
a web-based posting system provided by the workshop organizers. At the
end of this phase, the program committee will select 22 papers for
inclusion in the plenary session of the workshop. The format of the
paper presentation will include the presentation of the paper, the
presentation of the commentary, a brief response by the author(s), and
time for questions from the floor. All other accepted papers will be
presented at the poster sessions. All accepted papers and commentaries
will be included in the workshop proceedings. The workshop will also
include invited talks and panel discussions.
