Pull Planning for Unserviceable Parts in Connection With On-Demand Repair Planning
First Claim
1. A method for planning repairs in response to demand in a multi-level repair network, each level within the repair network comprising one or more repair locations at which unserviceable parts may be repaired, the method comprising:
- accessing a forecasted demand for a specified quantity of serviceable parts at a specified future time at a repair location;
in a first phase, for each of one or more inspected unserviceable parts at the repair location that are not repairable at the repair location;
estimating the earliest time at which a repair operation can begin for the part at an upstream repair location; and
planning a move order for moving the part between the repair location and the upstream repair location such that the part can be available for repair at the upstream repair location at the estimated earliest time, the move order having a start time and a delivery time;
in a second phase, for each of the one or more inspected unserviceable parts at the repair location that are not repairable at the repair location;
according to the forecasted demand and the earliest time estimated in the first phase, estimating a latest time at which a repair operation can begin with respect to the part at the upstream repair location in order to help satisfy the forecasted demand at the repair location; and
planning a repair order for the part at the upstream repair location at the estimated latest time, the repair order having a start time;
in a third phase, for each of the one or more inspected unserviceable parts at the repair location that are not repairable at the repair location;
according to the start time of the repair order planned in the second phase, re-planning the move order by modifying the delivery time of the move order according to the start time of the repair order and modifying the start time of the move order according to the modified delivery time of the move order;
the start time of the re-planned move order being an estimated latest time at which the part can be moved from the repair location to the upstream repair location for repair in order to help satisfy the forecasted demand at the repair location.

Abstract
In one embodiment, planning repairs in response to demand in a multi-level repair network includes accessing a forecasted demand for serviceable parts at a repair location and, for each inspected unserviceable part at the location that is not repairable at the location: (1) planning a move of the part to an upstream repair location such that the part can be available for repair at the upstream location at an estimated earliest time; (2) estimating a latest time at which a repair of the part can begin at the upstream location to help satisfy the forecasted demand, according to the forecasted demand and the estimated earliest time, and planning a repair at the upstream location at the estimated latest time; and (3) re-planning the move, according to the start time of the repair, by modifying a move delivery time according to a repair start time and modifying a move start time according to the modified delivery time. The re-planned move start time is an estimated latest time at which the part can be moved to the upstream location for repair to help satisfy the forecasted demand.
