We present an algorithm for summarizing the metric resource requirements of an abstract task based on the resource usages of its potential refinements. We use this summary information within the ASPEN planner/scheduler to coordinate a team of rovers that conflict over shared resources. We find analytically and experimentally that an iterative repair planner(More)
The trend toward multiple-spacecraft missions requires autonomous teams of spacecraft to coordinate their activities when sharing limited resources. This paper describes how an iterative repair planner/scheduler can reason about the activities of multiple spacecraft at abstract levels in order to greatly improve the scheduling of their use of shared(More)
