Managing an inventory of service parts
First Claim
1. A method implemented using a computer for generating a sampling, comprising:
- determining a total population of an inventory of members;
segmenting the total population into a plurality of segments;
determining a sampling error for use in analyzing the plurality of segments;
calculating, using the computer, a sample size for each of the plurality of segments based at least in part on the sampling error;
using a criterion measure for ranking members of each of the plurality of segments;
generating, using the computer, a set of random numbers for at least one of the plurality of segments, wherein the set is equal to the sample size for the at least one segment; and
extracting, using the computer, from the at least one segment the members whose rankings match the set of random numbers.

Abstract
An inventory of service parts may be managed by assessing a company'"'"'s capability, optimizing the inventory and implementing a management program based on the assessment and optimization. Optimizing target stock levels for the inventory of parts may be accomplished by calculating an inventory baseline for understanding information about the currently held inventory; developing a service strategy for a set of segments; quantifying a service level for each of the segments; analyzing the segments and their service levels for identifying at least one logistically distinct business; assigning each of the segments to a “best-fit” planning model for indicating each segment'"'"'s deployment, replenishment, forecasting and review characteristics; identifying a probability distribution function for estimating a demand process of each of the segments; and calculating a target stock level for each segment.
