Systems, methods, and machine readable media are provided for slot capacity adjustment. A utilization rate of a facility for a plurality of time slots is determined. Slots having a utilization rate that can have an associated capacity increased are identified and the capacity for the slots having a utilization rate that can be increased is increased. Slots having a utilization rate that can have an associated capacity decreased are identified and these slots have their capacity decreased. A slot-to-slot capacity variance of greater than a smoothing threshold are identified and smoothed. A capacity schedule is produced based on the capacity increases, capacity decreases, and capacity smoothing.
