Patent ID: 7457732

Claim:
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; an engine baseline modeling component that builds an engine baseline model from the preprocessed data, wherein the engine baseline model relates engine performance variables as a function of engine operating conditions; and a model diagnostics component that evaluates the performance of the engine baseline model, wherein the model diagnostics component includes: means for comparing engine data from a plurality of engines against the engine baseline model; means for generating engine trends for each of the plurality of engines; means for identifying correlations between the engine trends and various parameters; and means for calculating, for each identified correlation, summary statistics relating to the degree of correlation, wherein the model diagnostics component is configured to use the summary statistics to evaluate the performance of the engine baseline model, and wherein the system is configured to use the engine baseline model to perform at least one of monitoring engine status, predicting future engine behavior, diagnosing engine faults, determining engine performance, determining engine quality and designing new engine systems.
