Problems associated with spacecraft operation have grown dramatically as more sophisticated and complex spacecrafts are being developed. The emergence of a maturing artificial intelligence technology base, coupled with the development of commercially available special-purpose symbolic processing hardware, have opened up the possibility of extending the limits of conventional computer programs. A most pressing problem in space exploration is timely spacecraft power system sequence generation, which requires the scheduling of a set of loads given a set of resource constraints. This is particularly important after an anomaly or failure. This paper discusses the power scheduling problem and how the software program, Plan-It, can be used as a consultant for scheduling power system activities. Modeling of power activities, human interface, and two of the many strategies used by Plan-It are discussed. Preliminary results showing the development of a conflict-free sequence from an initial sequence with conflicts is presented. It shows that a 4-day schedule can be generated in a matter of a few minutes, which provides sufficient time in many cases to aid the crew in the replanning of loads and generation use following a failure or anomaly.
