Abstract: In an embodiment, a method for on-demand repair planning includes modeling for a repair location: a good parts buffer; a first buffer for unserviceable parts determined to be serviceable without repair; and a second buffer for unserviceable parts determined to be repairable. A forecasted demand, for a specified quantity of serviceable parts, is accessed. Parts available in the first buffer to help satisfy the forecasted demand is estimated. If a part is available, an operation plan is generated for a use-as-is operation. If the forecasted demand is not fully satisfied, a quantity of parts available in the second buffer to help satisfy the forecasted demand is estimated and, if one or more parts are available: the latest time at which a repair operation can begin is estimated; a repair order is planned; and an operation plan is generated for the repair operation.

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. Modeled for a location are: (1) an unserviceable buffer for parts inspected at the location and repairable at the location, and (2) a serviceable buffer for parts inspected at the location and serviceable without repair. 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.

Abstract: In one embodiment, a method for repair planning for a location in a repair network includes modeling: (1) an uninspected buffer for parts received but not yet inspected at the location; (2) a first buffer for parts inspected at the location and repairable at the location; (3) a second buffer for parts inspected at the location and not repairable at the location; (4) a third buffer for parts inspected at the location and not repairable at any location in the repair network; and (5) a fourth buffer for parts inspected at the location and serviceable without repair. The parts in the uninspected buffer are assigned to the first, second, third, and fourth buffers at corresponding rates according to an inspection operation.
