Advanced Planning Technology Knowledge Engineering Tools Presentations
Mission planning is central to space mission operations and has benefited from advances in model-based planning software, but developing a planning model still remains a difficult task. Mission planning constraints arise from many sources, including simulators and engineering specification documents. Ensuring that these constraints are correctly represented in the planner’s model is a challenge. As mission constraints evolve, planning domain modelers must add and update model constraints efficiently using the available source data, catching errors quickly and correcting the model. We described an Interactive Model Development Environment (IMDE) to configure mission planning systems by integrating modeling and simulation environments to reduce model editing time, generate simulations automatically to evaluate plans, and identify modeling errors automatically by evaluating simulation output.
This work was presented at the International Workshop on Planning and Scheduling for Space, held at the European Space Operations Center in Darmstadt, Germany. It was also presented at the Knowledge Engineering for Planning and Scheduling Workshop, held in conjunction with the International Conference on Automated Planning and Scheduling, at the University of Frieburg, Germany.
BACKGROUND: The Enabling Technology Development and Demonstration (ETDD) Program develops, matures, and tests enabling technologies for human exploration. The objectives of the ETDD Program are to:
- Develop and demonstrate prototype systems to feed the Flagship Technology Demonstration Program, the Exploration Precursor Robotics Program, and to support other Exploration goals
- Develop long-range, critical technologies to provide the foundation for a broad set of future exploration capabilities
- Provide an infusion path for promising technologies developed by other NASA technology programs
- Assess the feasibility of system and operational concepts resulting from architectural studies by building and testing proof-of-concept systems
- Develop exploration technologies that may also have terrestrial applications for clean energy and protecting the environment
NASA will develop and demonstrate integrated systems capable of managing complex operations in space and on extraterrestrial surfaces with limited human guidance. Technologies will address operations in extreme environments, efficient ground-based and onboard avionics systems and operations, and cost-effective human-rated software development. The top priorities are, in order of priority:
- Develop crew-managed autonomous operations
- Increase reliability and the capabilities of onboard systems
- Increase effectiveness and reduce costs of ground-based operations
