Abstract-- To generate plans for collecting data for data
mining, an important problem is information volatility during
planning: the information needed by the planning system may
change or expire during the planning process, as changes occur in
the data being collected. In such situations, the planning system
faces two challenges: how to generate plans despite these changes,
and how to guarantee that a plan returned by the planner will
remain valid for some period of time after the planning ends.
