Abstract
A system, method, and/or apparatus is provided for production processes in which online frequently derived measurements are determined use existing online and/or offline reference measurements and real-time and/or historical data to model process variables and/or product properties to achieve enhanced production goals.
Claims24
A method of frequently deriving online measurements associated with a production process for a product, the method comprising:
- obtaining a plurality of process variables associated with the production process and/or product properties associated with the product;
- determining one or more intermediate variables based on the plurality of process variables and/or product properties;
- obtaining one or more reference measurements from the production process and/or the product that are associated with the one or more intermediate variables;
- modelling a relationship between the one or more reference measurements and the one or more intermediate variables;
- repeatedly deriving the online measurements based on the modelled relationship and the reference measurements;
- and
- implementing the derived online measurements with respect to the production process.
A computer system configured to frequently derive online measurements associated with a production process for a product, the computer system including at least one computer processor that operates during the production process to:
- obtain a plurality of process variables associated with the production process and/or a plurality of product properties associated with the product;
- determine one or more intermediate variables based on the plurality of process variables and/or the plurality of product properties;
- obtain one or more reference measurements from the production process and/or the product that are associated with the one or more intermediate variables;
- model a relationship between the one or more reference measurements and the one or more intermediate variables;
- repeatedly derive online measurements based on the modelled relationship and the one or more reference measurements;
- and
- implement the derived online measurements with respect to the production process.
