                      Final 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 space;

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

We encourage attendance from members of all three of these communities.

The conference will consist of technical paper presentations, a poster
session, invited talks, and panel discussions. The format of the paper
presentation will include the presentation of the paper, the
presentation of a commentary by a member of a different community from
the author, a brief response by the author(s), and time for questions
from the floor.
