Model-based systems and methods for calculating raw material usage rates from dynamic inventory trend data
First Claim
1. A method for creating a model that can be utilized to calculate a material usage rate for a material from dynamic material inventory data, the method comprising:
- segmenting material inventory trend data into segments, wherein the segments comprise material inventory levels from one refill to the next refill;
serializing each segment so that each segment fits a unified time and inventory scale;
building an individual cubic regression model for each serialized segment; and
building a collective cubic regression model by combining all the individual cubic regression models together.

Abstract
Model-based systems and methods for calculating raw material usage rates from dynamic inventory trend data are described so that materials inventory may be monitored so as to allow for efficient use of the materials. These systems and methods also allow supply chain performance and operations management to be optimized. Materials inventory trend data may first be segmented into segments containing inventory data from one refill of a silo/storage vessel to the next refill. Thereafter, the data in each segment may be serialized to fit on a unified time and inventory scale. Models, preferably cubic regression analysis models, may then be created, and inventory levels on any dates within the models can be estimated therefrom. From these inventory levels, material usage rates may be calculated. These systems and methods may be accessible to users via web-based interfaces.
