Coordinating a Distributed Planning System

DSIPE supports a human planner. Although their requirements overlap for this mission, they each have independent goals (other missions to be performed or supported), capabilities, and resources. We extended SIPE-2's internal plan representation Throughout the planning process, each planning system monitors the local cell's planning activity for constraints and subgoals that might be relevant to other planning cells and notifies the cells of this information. For example, the naval planning cell might notify the Marine Corps planner that a particular landing area will be swept of mines by a specified time. Currently, the only constraints that are monitored in this way are the postconditions.
