Abstract
In one embodiment, a method is provided for planning repairs in response to demand in a multi-level repair network of locations at which parts may be repaired.

A forecasted demand, for a quantity of serviceable parts at a future time at the location, is accessed. In a push planning phase, for each inspected part in the unserviceable buffer, the earliest time at which repair can begin for the part at the location is estimated. In a pull planning phase, if the forecasted demand cannot be satisfied using parts in the serviceable buffer: (1) a quantity of parts in the unserviceable buffer repairable at the location and available to help satisfy the forecasted demand is estimated; (2) the latest time at which repair can begin with respect to these parts at the location to help satisfy the forecasted demand is estimated; and (3) repair for these parts is planned at the estimated latest time to pull these parts from the unserviceable buffer, from which they cannot be put …
