1. An apparatus comprising:
- a memory to store a data structure representing a multi-echelon network having one or more service parts; and
a processor and logic executable thereon to, for each of at least a subset of the one or more service parts,calculate, for the service part, a location within the multi-echelon network, for which allocating the service part to the location provides a greatest gain in system availability per item cost, wherein system availability defines a probability that the multi-echelon network is functioning;
allocate an additional instance of the service part to the location,recalculate the gain in system availability per item cost based, at least in part, on the additional instance of the service part allocated to the location, andrepeat the process of allocating an additional instance of the service part to the location and recalculating the gain in system availability per item cost until an average gain in system availability per item cost decreases.

Abstract
Embodiments of the invention are generally directed to a system and method for service parts planning in a multi-echelon network having one or more service parts. For at least a subset of the one or more service parts, a calculation is performed to determine a location within the multi-echelon network at which allocating the service part provides the greatest gain in system availability per item cost. In one embodiment, the calculations take into consideration violations of incremental optimal allocation. In an embodiment, the calculations take into consideration violations of convexity.

5. A method for service parts planning in a multi-echelon network having one or more service parts comprising:
for each of at least a subset of the one or more service parts, calculating, for the service part, a location within the multi-echelon network, for which allocating the service part to the location provides a greatest gain in system availability per item cost, wherein system availability defines a probability that the multi-echelon network is functioning; allocating an additional instance of the service part to the location; recalculating the gain in system availability per item cost based, at least in part, on the additional instance of the service part allocated to the location; and repeating the process of allocating an additional instance of the service part to the location and recalculating the gain in system availability per item cost until an average gain in system availability per item cost decreases. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. An article of manufacture for service parts planning in a multi-echelon network having one or more service parts, the article of manufacture comprising an electronically accessible medium providing instructions that, when executed by an apparatus, cause the apparatus to:
for each of at least a subset of the one or more service parts, calculate, for the service part, a location within the multi-echelon network, for which allocating the service part to the location provides a greatest gain in system availability per item cost, wherein system availability defines a probability that the multi-echelon network is functioning; allocate an additional instance of the service part to the location; recalculate the gain in system availability per item cost based, at least in part, on the additional instance of the service part allocated to location; and repeat the process of allocating an additional instance of the service part to the location and recalculating the gain in system availability per item cost until an average gain in system availability per item cost decreases. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
