Software for Planning in a Hierarchical Processing Environment

Decision-support software based on discrete-event simulation (DES) has been undergoing development for use in planning and scheduling work in the Orbiter Processing Facility (OPF) at Kennedy Space Center. The software is also suitable for adaptation to similar use in other facilities characterized by low-volume processing and by hierarchical processing environments with multiple subfacilities and with dependencies of tasks on resources and on the prior completion of other tasks.
