Optimized Deployment of Parts in a Distribution Network
First Claim
1. A method for deploying parts, comprising:
- defining a plurality of locations comprising a plurality of supply locations and a plurality of demand locations, a supply location being operable to supply a plurality of parts to a demand location;
computing a demand for each part at each location;
estimating an availability lead-time for each part at each location;
computing a lead-time demand for each part at each location using the availability lead-times for the part;
computing a stock level for each part at each location;
determining a completely filled demand from the lead-time demands and the stock levels;
determining a partially filled demand from the lead-time demands and the stock levels; and
generating a coverage function for the parts at the locations from the completely filled demand and the partially filled demand.

Abstract
A method for deploying parts is disclosed. Locations that include supply locations and demand locations are defined. A supply location supplies parts to a demand location. A demand is computed for each part at each location. An availability lead-time is estimated for each part at each location. A lead-time demand is computed for each part at each location using the availability lead-times for the part. A stock level is computed for each part at each location. A completely filled demand is determined from the lead-time demands and the stock levels, and a partially filled demand is determined from the lead-time demands and the stock levels. A coverage function for the parts at the locations is generated from the completely filled demand and the partially filled demand.

22. A method for deploying parts, comprising:
-
defining a plurality of locations comprising a plurality of supply locations and a plurality of demand locations, a supply location being operable to supply a part to a demand location;
computing a demand for the part at each location by calculating a demand at a demand location operable to receive the part from a supply location, calculating a dependent demand at the supply location according to the demand at the demand location, calculating an independent demand at the supply location, and computing the demand at the supply location from the dependent demand and the independent demand;
estimating a lead-time demand of the part at each location by receiving an ordered list comprising at least a subset of the supply locations, and repeating the following for each supply location of the ordered list;
calculating a probability that a supply location supplies the part to the demand location, given that no other supply location has supplied the part; and
selecting the next supply location of the ordered list;
estimating the lead-time demand at the demand location from the calculated probabilities;
generating a completely filled demand from the demands and the lead-time demands;
generating a partially filled demand from the demands and the lead-time demands;
generating a coverage function for the part at the locations from the completely filled demand and the partially filled demand, the coverage function describing an expected backorder of the part at the locations;
minimizing the coverage function; and
determining an optimal deployment of the part at the locations according to the minimized coverage function.
