Abstract
System, method and computer product for baseline modeling a product or process. A service database contains process data. A preprocessor processes the data into a predetermined format. A baseline modeling component builds a baseline model from the preprocessed data, wherein the baseline model relates process performance variables as a function of process operating conditions.
Claims33
A system for quantifying baseline model quality, comprising:
- an engine service database containing engine data;
- a preprocessor for processing the engine data into a predetermined format, wherein the preprocessor includes a data segmenting component that segments the engine data into a plurality of groups based upon specific engines and further based upon specific time periods during which each data element was measured;
- and
- an engine baseline modeling component that builds an engine baseline model for each of the plurality of groups using a regression analysis, wherein the regression analysis relates engine performance variables as a function of engine operating conditions.
1 more element
A method for quantifying baseline model quality, comprising:
- storing engine data in an engine service database;
- processing the engine data into a predetermined format in a preprocessor, wherein the processing includes a segmenting the engine data into a plurality of groups based upon specific engines and further based upon specific time periods during which each data element was measured;
- building an engine baseline model for each of the plurality of groups using a regression analysis, wherein the regression analysis relates engine performance variables as a function of engine operating conditions.
A computer-readable medium incorporating instructions for quantifying baseline model quality, comprising:
- one or more instructions for storing engine data in an engine service database;
- one or more instructions for processing the engine data into a predetermined format in a preprocessor, wherein the one or more instructions for processing includes one or more instructions for segmenting the engine data into a plurality of groups based upon specific engines and further based upon specific time periods during which each data element was measured;
- one or more instructions for building an engine baseline model for each of the plurality of groups using a regression analysis, wherein the regression analysis relates engine performance variables as a function of engine operating conditions.
